'05 GMC Sierra Lowering? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I've got an '05 GMC Sierra 4x4, 4.3L, regular cab. I don't want to go crazy, just take up some of the slack in the rear. If I remove the stock lifting blocks in the rear will I need angles shims to keep the pinion angle in good shape?

Also, supposedly with a torsion bar front end, people say I can just loosen the adjuster bolts to lower the front. Is this true for my truck?

Thanks.

I moved your post to 4x4. Maybe you will get a response here.
