In the rear of my truck i have 2" shackles, the 2" hangers, and no overload, and i have some -4 degree shims, but since the hanger install, ive had a slight vibration on take off and around 55-60, what shims are you guys running with this amount of drop?

 

I have about the same drop. I cut the leaf spring pads off and re-welded new ones on with the correct pinion angle

 

got ya, not up for that project right now, but great idea, im going to just shim this biieeetch

 

You'll need to measure the driveshaft to pinion angle that you already have, then see which shim you need(replace the existing shim) to end up at between 3-5 degrees.

 

i was changing my rear shocks tonight and notice my pinon is facing upward pretty bad. but i have no vibrations at any mph or take off. it doesnt hook even on a 15 mph roll so i cant even judge from a dig lol.

its werid how its so smooth for having such a bad angle.
