In the process of putting on disco axles, for those who have succeded; did you have to tilt the axle up a little to get the track rod over the leafs, would it go better with parabolic springs? Tis not as easy as it seams.:violin: The standard pivot arms on the springs are 100mm long what do you think the maximum size could be? 200mm?

With mine i put extended shackles on as it angles the spring down at the back slightly which helps with clearance,plus you will lose a bit of height because you need to space the axle away from the spring about 2" so the steering bar clears. You can't just angle the axle up to clear the steering from the spring because the diff will be miles out of line for the propshaft and the castor angle will be out too causing the steering to be all over the place.

Thanks again V8jon, I have been playing today with different settings and so far have come up with the axles lifted off the spring about 40mm the shackle extended about 40mm, this leaves the castor angle approx verticle; I have removed 3 lower leafs just for setup but I think I will be looking for some parabolics as the ubolts will now be too short, also think I will need a spacer for the prop as it feels tight, but the chassis is raised from the ground so when on tarmac with engine in will all change, I'm hoping for the better.

maybe before welding you should bolt it all together tight and then ratchet strap the front axle down tight (bumpstops) to ensure your trackrod clears the spring

i'm guessing it's a compression problem that is the risk as i've not messed about with this conversion

Fitting a RRC axle to my 80 inch trials vehicle. I have raised the axle with blocks approx 45mm and the track rod clears the spring keeping the diff raised slightly as per RRC installation keeping kingpin angles as designed on RRC. Problem on max lock the track rod fouls the shocks as they are too close to the track rod at full lock. I will be swapping the spring plates around front to back because the rears will bring the shocks furthur forward (which they couldnt before because the swivels were too close) now with the wider axles there is room to move them forward just enough to clear the trackrod from hitting the on full lock.

could have sworn I uploaded some pics on my website but theyre not up.

www.reconrovers.com there ars some pics. I have used swb rims on the front to keep the wheels inboard as muc h as possible and used offset rims on the back to keep the track the same front to back seems to be ok ish

Thanks for your replies, jai landrover, what were the kingpin angles in the rrc; is it slightly rear fron vertical, with my setup at the moment (nothing bolted) I have allowed 15mm on the track rod for the drop on full lock. Nitemare, thats a good idea, rachet them down will try that before completion.

I had the same problem with the trackrod hitting the shocker but i ran it for 10 months like that because even with the disco axle not getting quite full lock it was still better than a series axle.
I've replaced the shocks now for disco +2" shocks and fabricated some new mounts to get more articulation and to stop the trackrod fouling the shock,i've also cut the bottom mount off the spring plate as it wasn't needed anymore so it isn't acting as a plough in the ruts

This is it before with standard series shocks

And this is it now with disco shocks and modified mounts

Looks grand however I don't think the regulations for my club wil allow me to do such a mod infortuntly. Kingpin angles are very similar to the angle as fitted to a rrc
Disco or defender I.e the diff pinion has the same angle as a coil sprung
