Heavy duty. Nice finish. Perfect pin size.
I searched all over for the proper blocks and bought these 1.5" ones for my 2002 Silverado 1500 Base 2WD Extended Cab. Added a leaf and 2 degree shim for proper pinion and rear drive shaft angle. Lifted the front 2.5" with Eibach Coils as spacers were a pain. These blocks are thick metal and baked with a tough finish. Wish they came pinion-angle tapered in this design. Leaf pack center pin fit exactly into block top with no play. Block pin into axle spring pad had just a little play.

Hole not aligned correctly
Just installed the lift blocks and noticed both holes to be aligned with the leaf spring is OFF.I'll have to remove them and RETURN them.

Great lift blocks
Blocks are great. They do not come with U bolts. I bought some from auto zone that worked. They were 12.5in. Long by 2 5/8in. Wide I think.
