      Description

      Exacting Fastener Engineering. The ARP Valve Cover Bolt Kit; 8mm Hex is the definitive solution for securing the top end of your 2011-2016 6.6L Duramax engine, providing a level of clamping force that far exceeds standard factory hardware. These bolts are manufactured from a high-quality 8740 chrome moly steel alloy and are heat-treated to a staggering 180,000 psi tensile strength, ensuring they can withstand the extreme thermal cycles and vibrations common to high-output diesel performance. By utilizing these premium fasteners, you eliminate the risk of bolt stretching or shearing, which is critical for maintaining a consistent seal on your valve covers during high-boost applications or heavy-duty hauling.

      Leak-Proof Sealing Reliability. Engineered with precision-rolled threads, this kit ensures optimal engagement with the cylinder head, preventing the loosening that often leads to messy and hazardous oil leaks in the engine bay. The 8mm hex head design provides a substantial surface area for your tools, allowing for more accurate torque application compared to recessed or smaller-diameter factory bolts. This consistent pressure across the entire perimeter of the valve cover gasket ensures that your 2011-2016 6.6L Duramax remains clean and efficient, protecting sensitive electrical components and injectors from oil contamination over the long haul.

      Installation. Putting this ARP Valve Cover Bolt Kit; 8mm Hex on your 6.6L Duramax Sierra 2500 HD takes 45 minutes to install.

      Application. The ARP Valve Cover Bolt Kit; 8mm Hex fits 2011-2016 6.6L Duramax Sierra 2500 HD models.
