Height difference from Right to Left?

Just did the Rough Country Level and put on 18x9 18mm Offset with 265/65R18's.

couple of things are noticeable.

The rear axle appears to stick out on the right side about 1" further than the left.

There is also a difference of height from the left side to the right side. I did not measure before the lift so I'm not sure if the variation was there prior to adjusting the height.
With all four tires at 35PSI the center measurements are as follows;

LF 36 15/16 RF 37 9/16 +5/8"
LR 36 5/16 RR 37 1/16 +3/4"

Is this normal "within tolerances" or did the lift exaggerate this? Vehicle doesn't show any adverse handling characteristics.

My stock 2015 is 1in lower in the rear on the driver side then the passenger and I don't even have 25k on it yet. I plan on taking it into the dealer soon.

There's a dealer bulletin on this already. But no fix as of yet. I have it too.

I am trying to build a fix for it now as chevy seems not to care.

Not sure if any of you have tried this yet but I loosened the rear leaf spring end bolts and then bounced the truck pretty hard (my dad and I bounced on the rear bumper), his idea, then tightened the bolts.
It worked to get rid of the lean on my truck, it seems that the rear springs were either tightened while the truck was not sitting level or that the bushings twisted during transport.

It could be they're over torqued from factory....When they're over-torqued, they can't flex properly and certainly can't 'settle' when its first being driven.

Recommendation for anyone - is to find out what the proper torque is supposed to be (for all bolts - main eye, and shackles) and loosen and retorque. Or ask your dealer if they can check for proper toque on the rear suspension.

+1 on loosening and retorquing the spring bolts. It appears there's some binding in the bushings. Mine was about an inch off side to side when I got it but had worked itself to about 5/8 inch difference at 5000 miles. Redoing the bolts fixed the problem. And yes, you do both sides. Just for the record, Chevy says less than 1/2 inch difference is within specs.
