when ya say they have twisted do you meen one or two of the springs has come out of line with the others and can snag the tyre?

Aye its happened to 4 people i know who have had the pro comp cherry lift springs (bottom leaf swivvels and attacks the tyre) :?

[greggmo]

the sky jackoff ones do the same. the remedy is to get some of the clips that bend around the spring pack and keeps them in line. some springs come with em some dnt but thats all it takes to fix it.  

[garyf]

Still waiting for my replacements but got to say I will also be bringing this to their attention as i have just fitted new set of tyres and if they shred them I won't be 2 happy, obviously there is a problem with them and they need to be providing the goods to sort it out :roll: then the pimping film on the windows to finish it off.

[Sam]

Sam was it Dave Kirby who made you the bumper and rocksliders, I want to get rid of the chrome off of mine, got the lift on obviously, got the Mud boots on, snorkel is ready to fit when I have the balls to drill the wing     then the pimping film on the windows to finish it off.

no dave never made mine - i had mine done by a bloke in mansfield before dave started doing them. Dave will sort you out with anything you need though (its his new business now) hes done tony's (chickenlegz) and steves (revdoc's) cherries front and rear bumpers and sliders and he's cheap too give him a ring

This is what I mean by twisting


The bottom spring is a stop spring and not linked to others at all :?

[greggmo]

thats what i had in mind. the u bolts should be mega tight for a start(not suggesting they aint) also you could consider a little splat of weld near the spring perch to keep em in line. it is a pain though and like you have said it should not do this with a new kit and if it does it should come with a fix in the kit. have the guys at pro comp commented on this situation?

[The Smiths]

I like the idea of the weld on the seat  - should stop it twisting around.

Was thinking about making a strap to hold the leaves together near the perch so that it did not stop movement.

The U bolts are very tight.

Awaiting the next move from Procomp, I am saying that they are not fit for purpose - see what they come back with :?

[Mike Pavelin]

I would say it has something to do with the degree shim. If you look, it is turning as well.

The degree shim comes fitted in the pack.

The degree shim is twisting with the bottom leaf, these seem to hold together well, but they just pivot around the pin/bolt.

An extra spring clamp (Hendrick clamp??) will solve the problem.

Mine too, although they don't touch the tyre.  Maybe worth making some of these:

Had this problem with an old set of pro comps that did cut the tyre,got in touch with them and they sent me replacement springs no probs although it appears to be a design flaw and a clamp on the end would solve this.

[garyf]

The problem with the clamps like that are they need a securing point on the bottom leaf, the only way to do that is to drill a hole in the stop leaf, firstly have you ever tried drilling spring steel, secondly once you have done this they will reject any claim made a against them under warranty.

On the stock springs you are ok to use this type because all the spring leaves are close together, on the ProComp ones if you was to fit them without securing them they would walk up the leaf eventually and start to clamp the leaves together (if that makes any sense) hence you would loose the lift or suspension drop.

I have the idea of making a U bolt clamp similiar in design but then drilling a pair of holes and fitting the long bolt on top of the bottom leaf, hopefully this would keep the U clamp in place and then allow the leaves to rub on the 2 uprights that left, the only thing I am unsure about is how much pressure there is when they try and spin, if this is quite alot then it may bend the uprights and still have the same problem. This probably doesn't make a lot of sense to anybody else but I know what I mean.

[greggmo]

bit of a night mare. if you do go for a tack of weld just be careful with the heat that gets into the spring and that you only tack the bottom one to the one directly above it. i see what mike means about the shims but to be honest they never seem to be a great fit do they?

That sounds like it may work.  

It will need to be at least 8mm strip though - the bottom leaf creates a lot of force - I needed a 4lb lump hammer and a lot of effort to move the first lot back in place (and I'm not small).

The other thing I was thinking of was utilising the U bolts and using plates between them and the side of the springs and then perhaps bolting across the top and bottom to give more rigidity.

[garyf]

I've got some 8mm x 30 flat bar I will get bent tomorrow, I aren't using mine off road currently due to fitting snorkel, dis-connects, and a few other mods, don't know if you want to try on yours 'The Smiths' in the meantime PM me if you do

Been reading this thread with interest, as i have posted before i have ford escort van springs under the original top leaf on my xj, what may be useful to you is the bottom leaf overload leaf has a u shaped plate riveted to it  that stops the leaves from getting out of position , the problem you are having, have a look round your local breakers yards for a  y reg ford escort van and you will see what i mean. it would be easy to install under your springs also mine cost me £20 for 2 springs hope this helps...........

[dtooth]

I tried to drill the spring  :cry:  i have seen on the pro-comp web site some of the leaf pack have that clamp fitted .

[garyf]

Guy at Explorer contacted me has he said he would in relation to replacement lift springs and collected them today, they will hopefully get fitted tomorrow, while I was there I mentioned to him about the springs twisting and causing tyre damage etc.. they are fully aware and he is going to send me an e-mail that he has from the states. I will paste the email that is sent once recieved but I have seen it on his PC.

Got to say what it states actually makes sense, not saying that this is the problem but basically they are saying that there is a possibility that the spring centre bolt that locates in the axle case is bottoming out in the hole, possibly because the bolt is slightly too long or that the hole has a build up of muck/corrosion in it. If this is the case when you tighten the 'U' bolts up the spring is actually tightening on the bolt rather than the leaves.

I will check this on mine tomorrow to see how deep the hole is in relation to the length of the center bolt. if it is bottoming all that is required is to grind some off of the bottom of the center bolt.
