how do you get rid of chevy lean in the rear? my driver side rear is sitting lower then passenger side

 

leaf spring pack spacer.....
Raise and support the vehicle.
Support the rear axle.
Remove the U-bolt nuts, remove the U-bolts and anchor plate. Discard the U-bolts. DO NOT discard the nuts or anchor plate.
Remove the lower shock nut and bolt.
Raise the vehicle or lower the axle enough to allow for installation of the spacer. Install the spacer, P/N 15872657.
Lower the vehicle or raise the axle.
Install the lower shock nut and bolt. Rear U-Bolts P/N 15872657


and this is a section of another "fix"
Recommendation/Instructions:
Measure front trim height keeping in mind that the trim height tolerance is .5" difference side to side. Verify that the vehicle is equipped with the correct production front springs. You should measure the standing height of both front springs to ensure that they are equal height. Check "z" height measurements as per SI. After determining that the above checks do not influence the concern, install a front spring upper insulator, P/N 15756770 in the lower control arm spring pocket. Install 1 insulator at a time and measure the change between installations. A maximum of 2 insulators per spring pocket may be used.

I did both on my '06 and now it's almost dead level

 

When I took care of my lean in thefront, the rear leveled out. There's no sway bar back there, so whatever the front does, the rear will follow. My lean was bad almost 7/8". I ended up triming the pass. coil twice. First a half a coil, then a third. Now it measures 15" from fender to hub center, plus or minus an 1/8".

 

I have the Belltech 2/4 drop with the alignment kit. I haven't had any problems with the shocks, enjoying the ride all the same. I'm sure I or Eric will find something else.

 

did you use the Belltech alignment kit to fix negative camber issues? if so how did you like it and would you recomend it?

 

The issues that I was having was the vibration the DS was making. Yes the allignment kit corrected the vibration. I made the call to Belltech directly to have them listen to my situation, and the gave me my resolve.

 

does anybody have any idea if a 255/45/20 will rub up front on my 4/6? or am i going to have to go with a 40 profile?

 

I am running 275/40/20 with no issues!

 

well according to my tire size calculator your tire height from top to bottom is about 28.7 and a 255/45/20 is about 29.1 so if you have no problems at all i should be ok with the 255/45 no?

 

What wheel width and offset/backspace do you have?
