Thread: Range Rover Classic 93 coil springs

oops

I would use a 150 to 160 lb spring with spacers to achieve desired height, say standard RRC fronts for example, unless you would like to get some soft custom ones made up. Standard height for RRC is 470mm measured from centre of rim to centre of guard lip, same measurement front and rear.

Is 150-160lb still a bit firm? Or will the 133lb be too soft & body roll?

Okay, I did a quick measurement; 500 mm from centre of rim to centre of guard lip for the front & 510 for the rear;

So this means I have 30mm lift front and 40mm rear.

No 160Lbs was used by LR as the HD spec.
Usually you swap the green stripe rears to the front.
This gives 40MM lift.
LRA do a green strip which is 1/2 inch shorter. ( I use these as with a load in the back and the trailer on it goes nose high and loses caster)
Or you could go LRA blue stripe.
Unless you have stocK LR branded shocks specced for roll bar, the 133Lb springs IMHO are far too soft and result in much bump stop kissing. Any other shocks will not give you a better ride as they are valved stifffer than the LR ones.
Have a look here

mmmmmm, Having a 40mm lift in the front & back means any load I put in the rear will point nose in the sky. I think the perfect combo would be 25mm lift front with 150lb/160lb springs and 40mm lift rear using my existing springs.

Now how to achieve this?, I need about a 15.6" @150lb?

Check local rwc rules as to legality of spacers, when I do a conversion I use Disco rear springs of the desired height due to no load leveller on a Disco as in air suspension Classic. Disco springs are a heavier rating than Classic springs. Check out Dobinsons suspension out of QLD they have an online catalogue

I should check out Dobinsons, I only live a few km from their factory lol

Something to be said for the EAS?
None of these problems. Just the usual EAS ones!
I had some unidentifiable fault in EAS about 3 /1 years ago, even with my Rovacom diagnostics. Made a "manual" switch box from an old EAS CPU box so still going well; this runs compressor with pressure/temp cutout, then manual up/down of each corner. So always control height/level depending on the load of the day! Even drop front and raise back when shovelling out the trailer!
"Öne of these days" job is to pull out driver's seat and replace EAS wiring loom/computer and memory seat CPU that also deceased about 2 yrs ago.

I went thru coils 2 RR's ago, a 1985 that I fitted a Mitsubishi 3.3L turbo diesel.
Engine weight doubled that of V8 + bullbar, dual batteries, etc.
I sent all weights /specs to King springs, told them I wanted 75mm Fr/120mm Rr bump stop clearance and that's exactly what I got from them after a few weeks "bedding in". Those springs got a hammering for 2 years and only sagged about 10mm in that time.

240lb for the rear and 195lb for the front. I got this setup because I was going to have the dual batteris bullbar winch etc and was recommended this. I do have 140l longrange tank and an arb rear bar. I'm happy with the rear springs, quite soft and articulates very well. The front however is horrible. I removed the front stabilzer to help things but hasn't helped that much. Having no bullbar and an aluminium radiator has made the front quite light. I've also had to use 2 rubber spring isolators for each rear spring to stop the front being higher than the back even with no load in the back.

My plan now is to try and use around the 133lb pound springs in the front for now only trouble is the conversion I've done has around a 2" lift I think has 2" lowered shock mounts at all 4 corners using standard boge shocks + 50mm bump stops. This is the part I want to confirm. I've done some measuring; tyre profile at the moment is 245/70/16.

From bottom of tyre to the guard on the fronts is 84cm
the rears have measured 85cm.

I would prefer about 82cm for the fronts so I can add some weight in the rear so it doesn't point to the sky when loaded.

Can I have suggestions as to what springs/height size I would need. I want to fit around a 260/75/16 all terrain tyre in the near future as well, but the main thing at the moment is the harsh crappy ride from the front end + ride height.

It may be a while before I go winch bar/bull bar etc as I like the look of the front with nothing except the aluminium Bearmach steering guard. Looks sexy at the moment

Cheers
