Alright Searched a little couldnt find the answer I was looking for. Need some help on this one. Last year bought some 4" lowering leafs from someone on here (not saying th name) But they where junk! One leaf was welded the other leaf had half a axle shim and was falling apart.

well after making these leafs work I ended up with 3 inch's lower in the rear. Im using my old overload leafs also fyi

well the vibration I have, has gone from horrible to driveable, but not perfect. I was using the stock axle shims (2.5-3 degree) at first, that sucked. so I made 4.5 degree ones at work was better but still there.

My question is what are you lowered guys running for shims (degree)

the truck is ECSB 2wd with a 2 piece drive shaft. Im thinking 6 degree shims will do the trick, just need some back up on that decision.

 

With the 2 piece d shaft, it will be easier if you install a carrier bearing bracket to get the correct driveline angles.
Search ILUVDJM he has some pictures of his setup.

if you stay with the shims make sure that the fat side faces the front of the truck
