6" lift vibrations

Brantly · Jul 22, 2020

Just installed 6" rc on my 98 k1500, i have stock gearing in the rear end which i believe is 3.83. not sure if its gearing causing the vibration but at any speed it feels like rear end is bouncing. Im unsure if something is loose, the gearing is just causing weird tire rotation, my tires are unbalanced, or if it's the new add a leaf settling in? any suggestions

go through the rear setup and make sure everything is tight before changing anything - u-bolts, spring perches, lug nuts, etc. If everything is tight maybe your tires need to be balanced or you need shocks, or both

Pinion angle's probably outa whack.

Not just pinion angles, driveline angles as a whole are likely out of sorts.

The lift blocks in the rear end have a short side and a long side for drive shaft pinion angle. Make sure the tall side is to the back

Sounds like serious axle wrap.
