About this part

Product Details

When you're rebuilding the top end of your 2007-2011 GMC Sierra 2500 HD with the 6.0L or 6.2L LS engine, this Cometic Street Pro gasket kit gives you the essential components to seal it up right. This kit is specifically designed for the Gen-4 small block V8, featuring a 4.100-inch bore size and .051-inch thick Multi-Layer Steel (MLS) cylinder head gaskets.

Cometic builds these kits in the USA using materials manufactured domestically.
