Detailed Description

GBR 522-035 is a valve cover gasket kit for GM heavy-duty diesel truck applications. It is engineered to support consistent sealing performance where the valve cover meets the cylinder head, helping reduce oil seepage caused by aged or heat-cycled gasket material. For Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500, GMC Sierra 2500 HD, and GMC Sierra 3500 models in the listed years, this kit provides the sealing components specified for one side of the engine.

The GBR Valve Cover Gasket Kit line focuses on durable sealing materials and stable adhesion to the gasket base, which is important in high-temperature engine environments. If you are servicing a 2001-2005 Chevrolet Silverado 2500 HD or a 2001-2004 GMC Sierra 3500, 522-035 is a direct fitment-based option to match the OE application.

What It Helps Fix

• Oil leaking from the valve cover area
• Seepage at the cylinder head sealing surface
• Gasket shrinkage after repeated heat cycles
• Hardening or loss of flexibility in the sealing material
• Injector line connector seal wear on the listed applications

Clean the valve cover and cylinder head sealing surfaces thoroughly before installation. Inspect the cover for warpage and replace any damaged sealing surfaces before fitting the new gasket.
