Just got Tuff Country 2" rear blocks, been on my truck for about a month now. I misjudged the amount of lift the rear springs had (2" less then I thought), and I need 4" blocks to compensate.

The 2" blocks do have an angle on em to get the pinion angle right, and you will get the blocks with 2 sets of u/bolts- one set of used round top u-bolts for aftermarket setups, and one set of brand new square top u-bolts for the stock setup- both for the 12 bolt.

Looking for 4" blocks with decent u-bolts for a straight across swap.

Thanks!
