Product Details

Mahle GS33287 is built for engine rebuilds and head gasket service where accurate clamping force matters. Mahle gasket and sealing products are used by OEMs and technicians worldwide, and this cylinder head bolt set follows that same service-focused approach. It is a direct-fit hardware solution for many Chevrolet C10, C20, Camaro, Corvette, Impala, and GMC truck and van applications, along with additional GM passenger and commercial models.

Installation Notes

Follow the factory torque sequence and tightening procedure for the specific engine being serviced. Clean the cylinder head and block mating surfaces before installation, and verify thread condition before final assembly. Because this is a hex-head steel bolt set with no washers required, confirm the engine’s original hardware specification before installation.
