Dobinson Coils for a Disco series2

[Piddler]

Hi,
a bi over the sagged OME 40mm lift HD coils with the steel bar, winch and 2 batteries

Rang Dobinson today and inquired about coils.
As all salesman do they sai their 45mm lift HD coils will not sag, sit higher and be the Ducks N*ts.

Any members had any experience with them?

Cheers

I have Dobinson springs and shocks. They have performed great. Excellent value for money. Under $800 for the lot, fitted myself.

I've fitted quite a few sets on defenders, and are a good thing. BUT they have , as you found out, pretty average 'cataloging' and sales info.

Give Andrew or John a call at LRA in Thomastown, 94644094. They have about 13 different rates for LR's, and these are the most common ones I use now.
I have them on my Rangie, and after plenty of outback tripping and offroading I'm very happy with them.

Here is an extract from D2Au



When I originally bought the OME779 front springs, they were
already slight presagged by xxxx, but I still netted a
healthy 1.5" lift with the ARB bullbar (no winch). Then I fitted a
winch and my nett lift was reduced to 1" and over time this sagged
more and I was back to factory ride height. So my rear was starting
to look high with the nose down look which I didn't like. So I
pulled the OME779 out and fitted a set of Dobinsons 220lb/in springs
and I got back to about 1.5" lift.


I did an extensive amount of research on suspension for the D2 a while back, and the thoughts are that suspension packages that are around 220-230lb/in are required for bar, winch etc to prevent sag.

also this from D2Au



Also what springs on the front of a 7 seater with SLS are a good
match? I think the Dobinsons I previouly had would be too high as
they gave about 70mm lift(550mm hub to guard).

These are pre-settle measurements though.

Correct, I have fitted 200 to 220 lb springs to discos with winch and steel bar etc and have great results. Also, recently fitted LRA orange fronts and purple/ orange rears to a D1 Tdi with steel ARB bar and warn 9000 winch. Good bumpstop clearances and ride quality.

Yes you are right JC could or would not tell me any spring rates I like the ride of the OME springs and am a little worried the Dobinsons may be a bit harsh.

Thinking I may try them any way I am open to suggestions if any one has any as to what they are running and are happy with.

I would like springs that work off road yet don't sag. I am not after scary height just want to run my 265/75 tyres without rubbing and keep the excellent drivability with out going to high or harsh.

D2 TD5 Auto with bullbar only weighs 1.1T front, and 1.2T rear with a full fuel load. This includes alxe weight.

Here is LRA's spring rate/length/ride height chart.

According to their website:

The springs LR Automotive supply are as follows.

Dobinsons springs all around in my 130. Seem to be good. However very dissapointed with customer service. To cut a long and drawn out story short the heavy duty 110 or 130 rear coils in their catalouge don't fit into 130 top spring mount , 22mm thick spring dosen't fit into a 19mm gap - result - spring dosen't seat into top of spring mount. After this was pointed out to them they made a redesigned set with tapered turns at the top to fit in correctly. I suspect 110 models may not be as "heavey duty" in the rear end as 130 models , there seems to be an extra piece welded into top spring mount on my 130.

Thanks Heaps Simon,
this looks like what I needed.

No probs at all. I've not had anything to do with LRA, but you may find that all of those springs are ground top and bottom, and that is fine for the D2 rear, but the front requires a cut and dog legged spring. I'm not sure if they will do that or if you'll need to run a D2 rear lower perch up at the front.

[Pedro_The_Swift]

my D2 runs WHITE fronts,,
and I HAVE just installed a front bar(no winch)

so these should'nt sag overly Slunnie?

They're stiff for a front bar, but I doubt they will sag at all after the initial settle, even with a winch and duel batteries etc.

[Pedro_The_Swift]

is WHITE usual on the front of a D2??

[Slunnie]

Many manufacturers are back at about 180-190lb/in for a Disco2 front and these in my opinion and from what I could research in the US and in Aus are fine for no bar, marginal with a steel bar and will return to standard ride height with a winch on the front.

There are a couple of manufacturers that have rates at about 220lb/in including Dobinsons I think and ARB have revised their 779 from a longer 180lb to a slightly shorter 220lb/in for their full load D2 front spring. I run a lovells 230lb/in and no problem there yet either.

270lb is pretty stiff, but I know of these being run in Defenders etc without problem, but not a Disco2 front. I'd say that they'd be a more typical rear spring.

[Pedro_The_Swift]

I suppose the next question is why?
as in install these (I'm guessing from the factory-- ) on a D2?

The D2 has always been harsher at the front than BUB91,, (even with Nitrochargers :D)

maybe its just me comparing it to the luxo ride from the back half:angel:

[Slunnie]

Oh... Are these LRA (Rangie Spares) springs or factory springs? Factory whites according the above data are 110 military springs.

To get the luxo ride back you could look at softer rates with the appropriate length and/or shocks with softer bump valving.

[cucinadio]

Hay mate,

my bro has dobbies on his gq and goes pritty hard hes wrapped in them, im thinking of doin a 3" lift with both dobbies spring and shocks on my disco but im not decided yet

cheers

"remember it dont make no never mind"

[HAK]

hay all I dont know if this is relevant but Dobinson recommend 220 front for a bar equiped Disco and 240-260 rear they recommended 240 front and 280 rear for a 4 inch lift
