REDSS2NV Posted January 25, 2007 Report Share Posted January 25, 2007 I lowered my AWD with Spindles and Shackle/Hanger kit, and installed a 2 Degree Shim. It lowered it 2 in Front and 4 in Rear. I had NO Vibrations but it was too Low in the rear. I Installed the 1 " Belltech Shackles and took out the 2" Shackels and I got a small Driveline Vibration only underload or foot on gas. My Question is the 2 Degree Shim too much and need a 1 Degree??? Does the Hangers have any Effect on the Pinion Angle?? Thanks for your help.

CHEVY6000VHO Posted January 25, 2007 Report Share Posted January 25, 2007 You need to go with a 3* shim. That is if you were placing the shim in with the fat side to the front. Then again....with all the problems I've been having with vibrations......what do I know. Jim Quote Link to comment Share on other sites More sharing options...

Then again....with all the problems I've been having with vibrations......what do I know. Jim why do you say he needs a 3 degree shim? 1 or 2 degrees off will not make any huge difference. it may cause a little vibration but not much. what i tell everyone is to get their pinion angle measured . this will tell you how far out of wack your pinion angle really is instead of guessing. i had mine checked after i put in 6 degree shims and it was off about 2 degrees still. so it actually needs to have the leaf spring perches moved or an 8 degree shim ( 8 degrees is a little much for a shim ebut it can be done) . however everyones truck will not be exactly the same but dam close. if i were you i would get it measured and order a correct shim. mr p also had his measured with no shims and a 3 or 4 inch drop and i remmeber him saying he was 8-9 degrees off. so that tells you how well the kits were designed.

Today I put the Stock Hangers back on the truck but left the 2" Shackles with a 2* Shim and it rides Graet no Vibrations. I think I'm going to leave it like that for now. It was a Belltech Kit Thanks for your Help Quote Link to comment Share on other sites More sharing options...
