Description:
This rear block kit is specifically for use with 2011 - 2024 GM HD trucks with the factory overload springs which are on top of the leaf pack. If your truck has the overload springs it will have two bump stops mounted to the frame, one at the front of overload spring and one at the back of the overload spring. We did include an image in the listing which shows what these overloads look like. From what we can tell these overload springs were factory on 3500HD trucks and a paid option on 2500HD trucks. This kit features 2" tall fabricated / welded steel blocks rather than cast iron which can crack and break under extreme loads. It also includes new longer u-bolts to accommodate the extra 2" and very nice serrated & flanged nuts.

Contents:
2" Fabricated / Welded Blocks
New Longer U-Bolts (4)
Serrated / Flanged Nuts (8)

If your truck does not have the factory overload you will need BDS011218
