iirc the 3" kit requires the removal of the block. its a 2" shackle and removing the block gives you the other inch.

:word: but it also includes some spacers that go between the u-bolt nut and saddle so the u-bolts have enough thread....nice kit.

This has the block removed, shackles, leaf spring clamps and 2" spindles
