Rear SOA
By Kev on Mar 17, 2007 | In Dr Evil
Well What I did was a little more than redoing the shock mounts.
Follow up:
To start with we unbolted everything... and... then cut off all the stock leaf spring mounts and shock mounts.
Plasma Cut the Front Mounts off since they were a little bent and one side may have had a crack. We replaced with these 1/4" thick HD Leaf Spring Mounts for Yotas.
This allowed us to move the leaf springs up some and also got rid of the stock hanger I was always getting hung up on Rocks with. Now its all nice N smooth and I can hammer that mount all I want.
For the rear mount I used a setup for Yotas Also from All Pro. This uses what is called a Johnny Joint Setup. This allows the Shackles to rotate out with the springs giving a little more flex and not warping the leaf springs as much. This mount was pushed back also.
These also have greasable bolts... so they are always greased from the inside and the old nasty grease is pushed out by the new.
The next thing to tackle was the fact I always hated the spring under leafs... those damn plates were always hitting and the damn shock mount and ubolts were always bent.
So this involves New Perches New Plates and new Ubolts.
The new Perches were once again HD and extra long to help eliminate axle wrap.
The New plates were also long for the same reason and HD as well 1/2" thick.
Now if yo look at those 2 sets there are 3 sets of wholes... why? These are all drilled 1" apart and allow the axle to be moved forward or back depending on what is needed for fine tuning with out redoing the whole setup.
The plates needed new Ubolts as well so wome hardened 5/8th inch once replaced the thinner stock ones. plus that is what the plate needed to be correct.
OK now the springs are on... so if you look at the pic above you can see 2 additional things...
1. The brake line mount we cut off flipped and rewelded pointing up. THis gives alot of extra slack for the brake line during flex.
2. The new shock mounts on top of the axle picked up from a fab shop.
OK now the leafs were mounted... the axle is mounted the leafs and lower shock mounts done.
The upper shock mount we tried to use the stock crossmember there with some plate steel.... DONT DO THIS... it will not work or hold!!
Sow took some DOM Tubing bent it to give some better clearance for the stroke length of the shocks. Gusseted the top pretty heavy and added two bolt shock mounts. Located the spot directly above the axle shock mounts and welded it between the frame.
So the end result is Better clearance under the axle... the axle was pushed back 3" to make room for larger tires and better climbing.... Better flex... shocks are Rancho 9000s adjustable so the ride can accommodate the terrain, stiff on road and soft on the trail.... and everything is way over built so hopefully nothing breaks.
