i have rough country 4.5 full leaf packs with stock shackles. when going over bumps im hearing a thud from the rear. i though it was the shocks so i pulled out and hit some bumps and it still does it. from what i can tell nothing it hitting anything.
im thinking it could be my shackles. im just kinda stumped and its a really annoying sound. its a pretty good thud.

shackles you need extended ones for the RC leaf pack. when the leaf compresses the stock shackle smacks the frame. JKS has good shackles that have a bend in them so it takes a lot for them to contact the frame

Re check your u bolts? I'm not to sure. There's not much back there. Maybe rear sway bar?

Crazythingsido2

then why would they have me use the stock ones

Crazythingsido2

what swaybar? lol i think ive only heard of one person keeping the rear swaybar

Irongrave

dont know but when I did my friends we couldn't even use the stock shackles because the pack is too short end to end. if you look at the shackle angle on a RC pack is like / with the shackle pointing towards the front of the rig. you really want the shackle like \ pointing towards the rear.

i have the same problem after doing my 4.5" RC leafs...its the only negative thing I have found with the lift.

Mine did the same after my lift. Mine is the bushing on the shackle. Its gonna thud for a while becuase I dont have the time to take it off.

I just dont want to put a shackle in the back and have the back sit an inch higher
