Rear u bolt size 2inch lift block

[zack89]

I'm looking to get 2 inch rear lift blocks. How do I figure out what size of u bolts I need? I was looking on zone but have no idea what to look for.

A "kit" should come with new u-bolts. If it doesn't then look at another kit. I may do a small 2-3" lift. If I do I was going to get Motofab. Their kits are cheap and come with all hardware including u-bolts.

Order the u bolts from GM that come with a regular cab regular box Z71 (or 4x4). These trucks (mine) had the aluminum blocks standard (which I removed)

You can always purchase extra-long ubolts, mock them up with the new blocks and cut them to your preferred length. I'd paint them black before installing them as well.

 

As a side note, I wouldn't hurt to double up on nuts just in case.
