Rhino Backbone

[LandyAndy]

I was in an ARB store today,found an assistant happy to talk Land Rover.
Was looking at roofracks.
Told him I dont like the mounts on most of the D3/D4s except the very expensive imports.
Showed me (on his computer) the newish Rhino Bachbone mount.Looks a million bucks,low profile too.Anybody seen or got them,would love to see a real pic.

I like the Rhino stuff, looks neat. The only comment I would make is it looks like the black plastic trim has been removed underneath it. This would make it a permanent installation which to me would remove one of the real benefits of the Rhino rack - its very light and easy to take on and off.

Cheers,
Jon

[irondoc]

Looks good. Would certainly lower the height of the pioneer rack - I currently sit one on top of some Rhino bars which sit on the factory rails and it is pretty high.

Only negative I can see is that in the past when I have mounted stuff really low to the roof I get a lot more wind noise than when they are a bit higher.

Very interesting. Looks to be an alternative to the rails, to which different rack products (such as Pioneer) are then fitted.

So looks like these Backbone rails are effectively permanent but the Pioneer Platform or cross bars or whatever else they have would be removable, similar to their current stuff.

Would love to see one in real life.

In my case the fitment would be permanent.Love the low profile look.There are 2 widths availble too.

Great to see an off-road shop happy to talk Land Rover,it was ARB in Wangara for you WA folk.Earlier in the day I had 2 failed to be impressed by service by OL dealers,funnily enough both disapointed when I was getting bull bar prices.The second OL dealer was serving a D4 owner,he almost sounded rude,I walked out remembering him saying he wasnt interested in fitting a D4 bar.Was in there to buy an OL tyre deflator,ARB got the sale and into the future possibly a roof rack.

Using that mechanism voids the ability to mount anything below the roof rack for easy access, imho.

I have a front runner extended 2.2m, it is low profile and I mount a long handle shovel, spare HF whip and eye hooks underneath for securing loads.

Access is gained from the sides, this system would limit the ability for access and also washing the roof when needed once a roof rack lattice system is bolted to it.

[l00kin4]

I saw one of these with a Pioneer platform on a D4 a few weeks ago and was getting around to investigating what it was.


Looked very neat, nice low profile.

[strydes]

Certainly different to the other options kicking around and would look good with the Pioneer rack as a permanent fixing.

Even if I was in the market now though I'd still go for the Rhino tracks, it's really fast to put the Pioneer on and off, and when it's off, they're virtually invisible.

LandyAndy, which OL's did you go to, and what sort of difference in the ARB and OL pricing did you find? I have heard Welshpool OL are good and find their 2014+ bar looks just that bit better than the ARB one.

[LandyAndy]

They are both in suburbs that start with a W!!!!
Didnt get the roofrack price from them,when its time I will probably get one from OL Bunbury where I bought my bar.

I've found the same. I also have the full length Front Runner rack, and I have their camping table mounted on slides in under the rack. Because the rack is left permanently on my Disco, I like to have access under it for mounting accessories / washing / polishing etc - so I'm happy with the mounting arrangement on mine.

Speaking of Land Rover friendly 4WD accessories shops - the new Kalgoorlie ARB shop is owned by a family of Land Rover fanatics. :D They have a couple of ex military Defenders, a County wagon and at lest one Series LR. He often leads trips etc for the local 4WD club in his FFR Defender. Very happy to talk Land Rover and to find / sell products suitable to LR (including the full range of Front Runner racks and accessories). The Kalgoorlie OL store on the other hand - well, we won't go there. ;)

Today's projects in the shed while it's raining - picked up a housing for the Anderson Plug yesterday at Ashdowns, so I can mount the plug under the rear bumper and plug things into it without the need to take off the plastic cover over the towing plugs all the time - and I got some rubber clip-on strips and door seal from Clark Rubber down in Perth the other day so that I can tidy up the wheel flare cut-off above the ARB bullbar (one of the original rubber trims fitted by ARB us falling off) as well as fill in the gaps between the guards / headlights and the main channel of the bar. Then if I still feel active, I hope to fit new wiring and a fusebox under the dash for accessories so that I can free up the cigarette lighter sockets for SWMBO to keep her iPad etc charged up while travelling next month. https://www.aulro.com/afvb/images/imported/2015/12/271.jpg

Send some rain here Brian.
Its stinking hot in the shed.Went to do a couple of jobs on the camper trailer,couldnt trick myself into it.
Andrew

[BMKal]

Rained here on & off for a couple of hours this morning, and has been quite cool since. More rain / storms forecast for tonight and showers / storms for the next couple of days. :D

And only a couple of days ago, we got the hot spell that has since gone through SA with better than 40 degrees for a couple of days. :o

Just reading the forecasts for this year's Sydney to Hobart - looks like it's going to be a rough one - there's even talk of delaying the start.

I left my Engel in the back of Debs Territory whilst I had the windows tinted.I just swapped it back an hour ago.Temp gauge on the Engel was reading 65degC inside the fridge:eek::eek::eek::eek::eek::eek::eek:
Been bloody hot here today.

[LandyAndy]

People.
I drove past a 4x4 shop south of the river today.
They had a 200 Series and a FJello(or what ever they call them) with the Backbone racks on.They even looked good on them.When you see one on a FJello you will see why they needed to sort the backbone system,their roof is shaped like a banana :D:D:D:D:D:D:D:D:D:D:D

[irondoc]

Has anyone got a Rhino Backbone on their car that they could send me some photos of? I'm thinking of swapping...

Does anybody else not like the look of it?

You're not alone. I have only seen pictures, maybe it looks better in the flesh?

Same here. Jury is out until I see one in the flesh I suppose, but the pics I've seen so far don't do anything for me.

[AnD3rew]

I have a half length pioneer on short legs. It is very neat and as low as you can get I prefer it to the look of this backbone system. The rated weight for the roof is only 70kg total including the rack so there is not much point in having a huge rack up there. I reckon a spare wheel and four camping chairs and a camp table plus a foxwing pretty much maxes it out, and all of that fits on the half length Pioneer platform.

[Bytemrk]

I quite like the look.....

But i can see it being painful cleaning under the rack or getting tie down straps around some things.

[Magic]

I had a Frontrunner rack fitted to my D4 initially. We broke 4 out of 6 mounts on the road up to Mitchell Falls on our Kimberley trip. With hindsight, the mounts were never going to be strong enough for that kind of road.

I've just had a Rhino rack platform fitted with the backbone mounts through TJM. It is a permanent install, and so far, we've been very happy with it.

[irondoc]

Hi Magic

Any chance you could post some pictures of the backbone - in particular close up near the front so I can see what the track looks like without the protective rubber strip.

Cheers

Hi Lucas,

I'm out and about today, but will get some up tomorrow.

[RovingS]

First post here on the site and found the back bone system because of this thread, so thank you all.
I've posted some shots of it with out the rack, I'm making my own up.

It was easy enough to install, but in some spots it didn't quite fit as easy as I thought it should. The center 2 bolts are too high and have to be pulled down to meet the car, and the front one had to be pulled over 5mm to be located. The instructions said to remove the black tracking, which I did at first, found it looked like crap, drilled the holes in the black track a bit bigger and it fits just as good as if it wasn't there. Over all a very good product, thicker steel than I expected and I really like the look. A very slight wind noise, but with the ac or stereo on, and you would never know.

Steven

[LRD414]

Welcome Steven. Good feedback. What type of roof rack are you planning to fabricate? I guess you couldn't find what you wanted with a Rhino product.

Scott

Thanks Scott, nar the Rhino rack pioneer rack looks quite ok, but I'm a cheap skate at heart and I'll be damned if I can see the value. The backbone almost didn't happen, but I really like the look and I don't think I could replicate it.

I'm making up a platform trying to keep it all very low. I'm a landscape photographer so I want to be able to stand up there with a tripod, and camp up there with a swag when I'm on a long run. Still working out what I'm going to use for the base of it, but It currently looks like I'll be cutting off the tabs that come with the backbone so I can run a rail right along the side for better support.

Steven

[LandyAndy]

Looking forward to seeing the finished job.If it looks good I may do something similar.
I like the look of those backbones.
Andrew

[irondoc]

I put a backbone on today and took my factory rails off. I'm trying to get everything on my roof a bit lower.

I'm still undecided. It didn't fit as well as I thought it would - one side seemed to fit better than the other and one side is a bit bent inwards towards the roof compared to the other. The roof channels are exposed unless you put the Trim back on like RovingS did, so they don't look very good.

The rack sits on the nuts, so I am not sure about the weight limit - the original factory rails had a broad base that spread the load across the whole rail, these have four legs which sit on the nutsert things, so the weight is concentrated.

Time will tell...
Cheers
Lucas

[RovingS]

Well time for an update :)

Ive completed the platform and I'm happy enough with how it came out. I'm not a metal fabricator, so it took me way too long to do. But my time is free right.

I used one piece of channel (50mmx25mmx1.6mm) around the edge, then put in 4mm weld mesh. The cross braces are (25mmx25mmx3mm ) angle. They are only about 300 apart which has made it heaver, but as I want to stand up there, it was needed. If you didn't 450 would probably be fine. Cut the holes, painted then put on the roof for a test drive... found it to be way way way to noisy. Pulled it off and welded every where the mesh touches the cross members. re painted, mounted and its super quiet now. Really you have to turn everything off and focus on listening for it even at 100. Its 2.3m long and tapers from the front 1.17m to the back 1.1m following the backbone

Steven

[LandyAndy]

A job well done:cool::cool::cool::cool:.

I commend how you've carried the design holes in the backbone over to the platform frame. Clever.

Still not fussed personally about the backbone, but you have done well indeed.

Ron

[LandyAndy]

I like the backbone mounts,now to decide wich way to go,custom rack like that or Pioneer Platform.
My boy is getting pretty handy with a tig so may well go for a custom alloy rack.

It was something I wanted from the start, but wasn't prepared for the time that it took to drill those bastards lol, 12 holes in only 2 hours :)

[shanegtr]

just ordered a pioneer platform and backbone this afternoon. Should arrive Monday all going well

[rhinosm]

:mad:I ordered mine 5 weeks ago. Still waiting.
Keep getting told next week.
Rhino Rack have said the shipment has been delayed again and now due mid next week.
So that probably means to me a week later.
Not happy Jan!

[LandyAndy]

I saw a backbone rack on a D3 the other day,I really like it.
Seen lots on those fugly tojo abominations.They need it as the roof is shaped like a banana:D:D:D:D:D

Bugger, I ordered mine and 2 days later it was in the shop.

[rhinosm]

Now I'm really jealous.
I ordered a tradie rack.
Maybe if I ordered from W.A. and get it shipped to Vic it would be quicker.
I could take the D4 for a quick spin across to WA to collect.
Still be quicker, these clowns can't even give me a confirmed date.

[shanegtr]

Well, I didn't get the tradies rack just the largest platform they have

Shane that looks a million bucks.Im guessing you are happy with it???
That is the largest platform,correct???
Much increased wind noise????
Let us know how it effects your fuel economy when you have had it for a whilst.

Hi Shane
Can you please advise which width yours is? 1426mm or 1236mm

I've just purchased a 2011 D4 SDV6 HSE with e-diff.
However it doesn't have any factory roof rails ( not standard on the HSE back then)
I had the pioneer platform on a NW Pajero and its been excellent.
Unfortunately its a little to short to match up with the back bone rails hence a new complete platform, all rack accessories will be transferred over.

My concern with the wide rack is will the overhang be to large with an awning on the side.

Rhino are also stating 100kg load is this correct?

Craig

[LRD414]

My concern with the wide rack is will the overhang be to large with an awning on the side.
The standard width recommended by Rhino is 1376
No issues with awning, this is mine (on legs not backbone):
https://www.aulro.com/afvb/images/imported/2016/06/281.jpg

The narrow version is 1236, which used to be DIY fit only (width not recommended by Rhino) but this may have changed.
Awning can be fitted with this one too.
This is the one Jon had (on legs not backbone):
https://www.aulro.com/afvb/images/imported/2016/06/282.jpg

Other details and info here:
http://www.aulro.com/afvb/l319-discovery-3-4/195993-platform-vs-tray-vs-basket.html


Rhino are also stating 100kg load is this correct?
Yes for the rack but not for the vehicle, which is 75kg or to be more specific:

Maximum roof load is 71.8kg (less the weight of the roof rails & cross bars) for "Factory Roof Rails & Cross Bars".
For the Expedition Rack it lowers again to 54.3kg (less the weight of the rack & rails).
IIRC it's in the manual but also Sniegy's post here:
http://www.aulro.com/afvb/d3-d4-rrs/...f-loading.html (http://www.aulro.com/afvb/d3-d4-rrs/145885-discovery-4-roof-loading.html)

These are dynamic figures. Sniegy's comment from the same thread:
"While the vehicle is stationary it can increase, but i do not have a load reference for it"

Same for me with the 1376, no issue with the width. Mine's on the factory long rails:

Mines the 1426mm width. I can get a front on pic if you like to show the overhang

[jon3950]

As Scott said, I had the 1236 wide rack which was a nice neat fit. I also fitted a small Rhino awning to it which fitted below the rack and neatly over the curve above the doors.

This is the only photo I have to hand of it at the moment but I can probably find something clearer if you want it:

https://www.aulro.com/afvb/images/imported/2016/06/270.jpg

I liked this as it was a very compact set-up. However, if you wanted a bigger awning like a Foxwing you may have clearance issues. I have just bought a Rapidwing for the Defender and I don't think I could have mounted it the same way as the bag is much bigger and would probably foul the body. Can't be certain about that but you would want to check it out carefully before committing to it.

Cheers,
Jon

[jon3950]

Found another photo that shows it a little more clearly:

Since March I've done quiet a few trips to Perth and back to Tom Price, but mostly its been towing a car trailer so a bit hard to compare.

[LRD414]

Not missing it somewhat are you? [emoji6]

[hv_man]

Thank you for the additional pictures

I think I've decided I'm going to go with the 2128mm x 1236mm backbone system.

I'm really surprised by the low offical weight limits especially when you see the factory expedition fit outs LR have done.....

75kg is less than the Pajero's 100kg :mad: ....

[jon3950]

We had some great trips in it and it was such a brilliant vehicle that of course its hard not to miss it to some degree. I am having so much more fun with the Defender though I haven't regretted the decision at all.

Hi Steve, great photos of the backbone mounts. I was wondering if you had any photos of the plastic drilled out bigger??
As I've just bought the same and don't want to remove the plastic either.
Many thanks Michael.

Hi Mate, Just came across this comment, I'll get some photos later today If I can and let you have a look.

I had the Rhino Aero bars - just used the same legs and attached the small pioneer tradie - not sure the backbone would go lower

Hi Gub
Did you use std LR roof rails?

[LandyAndy]

Can somebody with a Rhino Backbone take some measurements for me please.
I'm wondering if I can mount a Land Rover Expedition rack to them.
The Expedition rack is wider at the front than the rear.1200mm front and 1130mm rear(its current used bolt holes).
Was wanting to know the same measurements on the Backbone.ie width of backbone at roof rack mount front and rear.
I'm thinking if the expedition rack is too noisy,or not suitable I can simply put a platform on later.
Thanks
Andrew

[Leyland1980]

Does anyone have any height measurements for the back bone with the pioneer platform (D4).

In access height and std if possible.

Cheers

John

[hv_man]

I'll take some measurements later this afternoon.
In normal with the maxtrax on the roof I'm <2.1m

[shanegtr]

My D3 from the floor to top of the platform is 1970mm at normal height and 1920mm in acess height

Hi guys
For my roof platform I used rhino tradie bars (3 of them) and had a local security door manufacturer make a "door" to fit less the insect mesh. Bolted it to the bars with 6 mm mush head screws into flat nuts which slide into roof racks
Works really well with light weight and a fraction of the cost of proprietary platforms only adds 25 mm to the height of the bars and gives lots of tie down points to the mesh (even came powder coated in black)

Can anyone with the backbone let me know how high it sits from the roof at the rear? I have a sunroof at the front and the DAB antenna at the rear. I reckon that I'll need 60mm to clear both items, but the backbone looks lower than that.

Lowest part of the platform to the roof is 50mm

[bakerdavid]

Thanks Shane - really appreciate it. I had no luck finding specs online, and the guys at the shop didn't inspire confidence (they were more interested in how "mad" the backbone would look).

Which it does, of course, but mad looks won't necessarily make it fit.

[Redback]

All I can think of with those backbone rails is wind noise, the platform is bad enough, those holes would make it worse wouldn't it:confused:

[shanegtr]

The rack that I had on my old 80 series landcruiser was significantly noiser - but that also had significantly worse sound deadening. I don't really have that much of an issue with wind noise from the rack as a whole

[Victim]

Lowest part of the platform to the roof is 50mm

Excellent - I've been curious about this too. I'd originally assumed the DAB antenna wouldn't be an issue as it only needs approx 40mm to clear it. My concern arose due to this statement in the online Rhino specs:

"Vehicles with options satellite aerial will require extra components (sold separately). See fitting chart for details."

So I checked their fitting chart, and it lists in addition to the standard fit kit (1x RD4B1) for satellite aerial you also require: 3x LHS2PAIR and 3x B103-BP

Is the "Satellite aerial" is something different to DAB antenna...?

[CU55TM Disco]

Sorry for the bit of a grave dig, but I am considering manufacturing a "Backbone" style rail for my D2.
Could somebody tell me what thickness material the backbone is manufactured from, the rhino site only states "steel".
From the previous pics it looks to be between 4 and 6mm.

Thanks.:thumbsup:

[gofish]

There is one on ebay ATM with a rhino platform for $650 ONO for those interested. I would love to buy it, but after just buying a kayak my chances of getting it past the financial officer are zero [bawl]

[Victim]

Could somebody tell me what thickness material the backbone is manufactured from, the rhino site only states "steel".

A rough check with a steel ruler in the dark looks like it's 3mm. I can check it properly tomorrow with a vernier (and my reading glasses...) [bighmmm]

[Victim]

Checked again today in the light (and drizzle...), Rhino Backbone is 3mm steel. A couple of pics attempting to show Backbone mounting detail:

120828120829

[CU55TM Disco]

That's awesome, thanks for that. I wonder why mild steel, and not aluminium???

[DiscoJeffster]

I fitted my newly purchased Backbone and 2100 x 1400 (odd) platform. Lovely and sturdy, able to climb all over it. Add two c-channel cross bars to it to mount the rook box to when I want to use that. Also added a 6" work light to the rear. I'll post up photos soon.
