I recently did a U-bolt flip along with the Deaver 8s. I used APs "long" lower shock mounts and had the welding done at a shop I have used extensively. I wanted to be able to use Bilstien 5100s and this required relocating the stock upper shock mount back about an inch ("boxed" frame at this point to allow relocation) and the D side leaf is able to fully compress to stock bump stop (the factory rubber piece is welded to the plate on top of the leaf pack) with the 5100. The P side, however, would only compess to the point where there is about 3/4" before the rubber hits the contact point on the frame. Ideally the P side stock upper would have been relocated like the D side, but the guy I was having do all this said it would be OK; that the 5100 have internal bump stops. Well several (dozens) full comps on the P side now and the shock is toast (entire force of compression on the shock and the stock upper mount has bent up a bit). Two questions I need help with are: 1) Is it Ok to compress Deaver 8s to slightly neg arch as D side set up allows? 2) Should I just raise the P side bump stop so that it takes the load before the shock or go ahead and try and find someone to help relocate the upper shock mount? (No longer live in Tucson where work was done) I very much notice the extra travel and hang wheels much less now. On the + side it is set up so that full droop does not pull the shocks on either side.
