Modifying a Perentie...

given they are not "ordered with 50mm lift" they were built to a specification...

More than happy to go Toe to Toe with both the DOT and an insurance company...

again, in fact... :)

its a pretty simple fight really... see the fording depth marker on the fuel tank.. just measure to the bottom of that... or you could just qoute emei Veh G 101 or even the UHB probrably right around say section 2 page 11 para 28 under the heading of

overall height
laden 1953mm
unladen 2040mm

height of cargo tray from ground
laden
710mm
unladen
825mm

towing pintle height
laden 520 mm <-- changed this on edit.. I miss read the look up table
unladen 640mm

Having recently had a Defender certified, whilst there are plenty of vehicles running 35's , no engineer will plate the vehicle above the allowable specs.
It will get knocked back, so submit the vehicle on allowable tyres..

That's fair enough. Don't bring that tow rating up again, we'll end up having that argument again too! :p

I guess the thing to remember is that if you want to add any more lift to a Perentie - suspension wise - you'd better have deep pockets!

I reckon for what Dauntless is after, he's probably better getting a single cab 130 and putting a 4bd1 in it. It would work out a bit cheaper and less engineering/certification hassle than modding a Perentie.

Of course he could get a tray back 6x6. That would fill most of his needs except for ease of parking!

Thanks for these:

overall height
laden 1953mm
unladen 2040mm

height of cargo tray from ground
laden
710mm
unladen
825mm

towing pintle height
laden 710 mm
unladen 640mm __________________

I might go out and measure mine tomorrow, I think mines come out a bit higher than it should be with the new suspension fitted. Hopefully the springs settle down a bit in the next few months.

I'm not sure you've thought a great deal about this. Putting a 4bd1 into anything costs a huge amount, after which you end up with basically stock Perentie.

Unless you want to do the mod project because you enjoy projects, I'd recommend just buying something that already will do the job.

As for me - I'm halfway through my project so I cant talk!. I do have an engineer working on a certified tow bar tho

Umm why? you can add 2 inches of lift without any re-engineering.

in fact clever people just go and grab the suspension and spec list for the rsv or rfsv and use that as the stock heght measurements or grab the RFSV springs and shocks.

because while para 28 of its UHB says Tray body load area

para 29 has this..

height of cargo tray from ground.
laden 770mm
unladen 870mm

towing pintle height
laden 610mm
unladen 710mm

and last time I checked the RPS's the springs and shocks have different part numbers...

Hrmmm...

something about

"so long as it was available in the model range at thetime of production" might ring a bell...

someone very cleverer could put forth the argument that as its in the same family that you could, in fact put suspension in that gave you say 110-120mm of lift over the stock GS/FFR and have it be legal...

and my appologies for the edit on the previous post of mine to correct the pintle hook height, landies are good and all but generally the loaded pintle height is going to be lower than the unloaded one.

Umm why? you can add 2 inches of lift without any re-engineering.

I meant adding 2" to a Perentie from where it is now, which would mean 4" from a stock 110/Defender.

As far as I can tell from what I gleaned when I was looking at the suspension, due to it's design, the perentie is pretty much about as high as you can go before you start having to replace the drive shafts with double carden jointed ones ($1500-2k ea)
you also need to replace the drag links and radius arms as the stock onees will be too short/the wrong angle, the steering linkages will need to be replaced with longer/adjustable ones as well (panhard rod?).

Everything I read said that going higher that a 2" lift on a defender would require those additional changes; which i take to mean adding any further suspension height to a Perentie would require them.


I could be (and quite possibly am) wrong though.
RE: getting part nos from the RFSV etc. It is higher than the the GS? I thought it might have a heavier spring rating, but from the 2 I've seen in the flesh, they seems the same height as my GS.

I'd be careful relying on user generated documents emei xxxx or uhb xxxx ;) but base your decisions on the land rover part numbers.

Agree - you'll be much happier with a coil cab GU patrol ute and a readily available rear coil brace. Ticks all your boxes and then some.

Yes, I currently own a Perentie and a Patrol. Love my Perentie but it is what it is...
