I have some leftover 1"x2" high grade billet aluminum stock that I have cut down to leghth for lowering blocks. These are great for fine-tuning your rear ride height for coil-sprung rearend trucks without affecting ride characteristics. These blocks will need to be drilled for u-bolts. A set(2) of blocks are $20 shipped and will lower your truck 1" in the rear. Please email Robert.Noe@xerox.com
