Description

The Cometic Gasket C5751-120 is an MLS head gasket designed for GM LS Gen-3/4 small block V8 engines from 2014 to 2017. It features a 4.060-inch bore and a 0.120-inch compressed thickness.

Constructed from multiple embossed layers of stainless steel coated with Viton rubber, this gasket offers maximum sealing performance without the need for additional sealants. Its multi-layer design is suitable for aluminum head to aluminum block applications and aluminum head to cast iron block configurations, effectively handling shearing forces.
