Did a quick search on this and couldn't find any info. Is anyone out there running this setup and ifso what do you think of it, thinking of doing this on mine so i can runn off the shelf shocks instead of getting revalved ones all the time.

Front or rear?

Mainly the front due to the extra weight over it, but will probably do both

Graeme Cooper does a rear conversion for Range Rover Classic and Disco using a set of Bilstiens and the standard shocks, whatever they are., and three people in our club have them. They swear by the lack of fade on corrugations, and reckon that it doesn't affect the ride!
As they all have quite strong springs and 2-3inch lifts also, one with 19mm wire, I find this a bit hard to believe, but there you go.

Don't know of any front conversions but should be simple enough using an air suspension turret.
I wonder whether using premium shocks with reservoirs doesn't accomplish the same result with no insurance or engineering implications.

Max has a dual front setup that seems to be pretty good.

I've gone the revalve approach, running single rear, but had Bilstein alter them to stiffen them right up. Bilstein by design dont fade.

QT Services in the UK make a kit. It doesn't seem to complicated to fab up the mounts.

Yep I've got the MJ Lee fronts in, been a year now. Can't see them anymore on the MJ Lee Engineering site, but thay are a good thing. PM me if you want a pic.

We installed them to offset the kneel and understeer that comes with Sam's holey bushes. They help in the turn-in phase of a corner. Makes the ride a bit pitchy though.

And the front/front shocks connect to the radius arm bolt, i.e. they act through the bush, not directly on the axle housing. They've chopped out a set of holey bushes in 6 months, we've just gone to std bushes in the front of the radius arm, and holeys in the back, as a compromise.

Had dual rears on the last car, the Disco. This was to help the fade on a tail heavy car on long trips. GC's conversion worked very well.

But whether f or r, it does make a difference to the ride. You'll get told it shouldn't coz each shock is only doing half the work, but it does.

what is needed is 1 rebound shock and 1 compression shock on each corner.riding dirt bikes you learn how much difference a good set up makes.if you can tune your comp and rebound to suit the vehicle you drive it would make things so much better.with a rancho or other shocks you can adjust ,you gain a bit but no where near what you could get with a comp and rebound set up. who makes a rebound and compression shock set up because i want one.

Hi All

Just done my Third rear twin shock conversion, (A Disco 1 and two 110's.) The results are fantastic.
I use Dobinson shocks for some of these conversions, as they seem to last really well for the money, and in a twin application cost about the same as 1 Bilstein.
All the vehicles have been done to remove fading at high speeds, loaded on corrugations, and / or towing offroad in the dunes etc in high temps etc.
I have found that front shocks seem to be a non issue if you use single Bilstein, DeCarbon, Koni etc. I haven't seen a need as yet for twin front for these abovementioned vehicles, although 1 of them has a heavy bar and winch fitted, and could possibly benefit from some more control if pushed hard.
I've also fitted twin DeCarbon's to the rear of a Disco 1 with Scorpion EVO suspension, this vehicle being used to tow an Ultimate Camper through the Simpson and the Canning etc, and being used for serious off road when at home.
I find the DeCarbons to be absolutely the best ride quality for all coil sprung RR or LR.
If you want any, even +2" front and rears, I have a steady supply secretly into this country, PM for info etc...

I have an extra 110kg over the front axle due to the motor, plus winch and bar, that is why i'm looking at doing this front and rear

Sorry 6.5 RR, I'd forgotten about the weight of the big block over the front!
I have a 4BD1 Isuzu Turbo, and this as yet hasn't caused too much of an issue with handling, using single DeCarbons and RAngiespares Orange rate springs. I have a 40Kg steel TJM winch bar with no winch though, and second battery is in the back.

Any pics when you're done??

Yeah if i could post them i would, will see what i can do. I'm running RS purples in the front and until i put the bar and winch back on i can't measure the bump stop clearance. but i'm just curious about the shockers handling the extra weight, i know the springs hold the weight but surely the shocks have some affect on it!

Purples are the next one up from orange, youve got 220psi but about 1/4" less free length.
I would say that single bilstein or koni would easily handle this rate/weight if you arent into competition work ...

The rear of a RR, DEF or Disco does a lot more work than you think, even if you have more 'weight' over the front, the back end does get SLAMMED into the ground when coming down off even a small bump or through a small dip.

I had toyed with the idea but I tested it out on a horror bit of road fully loaded , 330km corrugated bulldust etc and found no evidence of fading from the front or the rear for that matter, so I'll stick with the spring rates and shocks I have for now.
