The MAHLE GS33784 Engine Cylinder Head Bolt Set contains all the head bolts necessary to replace one cylinder head during engine rebuilding or head gasket replacement. This application-specific bolt set is engineered to deliver the precise clamping force required to seal combustion chambers, oil passages, and coolant passages—even under extreme temperatures and pressures.

Key Features:

• Complete cylinder head bolt set for single head replacement

MAHLE Original is a trusted OEM supplier manufacturing world-class sealing and fastening products. Torque-to-yield bolts undergo permanent deformation during installation and cannot be reused—always replace head bolts during cylinder head service to ensure reliable engine sealing and prevent gasket failure.
