I saw a post in another thread about taking out the factory blocks. What does that do?

for the 99-06 Silverado/Sierras, the block is the only difference in the rear of a 1500. A 2wd does not have the block, and the 4x4 do. Take out the block, and the rear will sit about the same height as a 2wd.

you'll need 2wd u-bolts if you take it out.

I am looking for some nbs 2" blocks with ubolts if anyone has a set.

Sorry if I am threadjacking...
