I have a new 2500HD 4x4 ordered. I tow a lightweight 5th wheel with it so would like it to set a little lower. Also, it is easier to get in and out of a truck that sets lower. So, I have a set of lowering shackles ordered (the GM dealer told me that won't void my warranty as I only am lowering the rear by about 2"). They told me that once those are installed, I can decide two things - do I need to install pinion shims, and does the front need to be dropped by 1/2" to 1" by simply uncranking the torsion bars and realigning.

My question is: Are there any negatives to uncranking the torsion bars to lower the front end a small amount such as 1/2"-1"?

I have had my torsion bars uncranked for about 18 months with no ill effects at all. I lowered the front of mine ~1".

I also removed the lifting blocks in the rear and had no problems with that either. You won't need any shims. The pinion angle will be fine if you just remove the blocks.

I would get that statement in writing from the dealer about them not voiding your warranty. Who knows what kind of crap they might try to pul....
