Restore your diesel engine's reliability with this all-in-one Duramax Head Gasket Repair Kit. Whether you are fixing a blown gasket or building a high-performance engine, this configurable kit includes everything required to get the job done right.
Product Overview:
This comprehensive kit eliminates the guesswork of sourcing individual parts. It features high-quality Upper Engine Gasket Sets and customizable options for head gaskets and fasteners, ensuring a perfect seal for your specific horsepower goals and budget.
What's Included:
• Upper Engine Gasket Set: Complete seals and gaskets for the top end of your engine.
• Grade C Head Gaskets: Select from GM or Mahle/Victor Reinz (Left & Right).
• Cylinder Head Fasteners: Standard head bolts or high-strength stud upgrades.
• Optional: Set of 8 Bosch Glow Plugs.
Customization & Recommendations:
• Gasket Selection:
• Mahle / Victor Reinz (Recommended): Due to recent GM price increases, we highly recommend these gaskets. They offer superior quality and durability at a better value than the OEM option.
• GM Grade C: Available for those preferring genuine General Motors parts.
• Head Stud Upgrades:
• Standard Head Bolts: Factory style replacement.
• Xotic Head Studs (Top Pick): Our team has used these on countless trucks. They provide strength and reliability nearly identical to ARP 2000 series studs but at a more accessible price point.
• DogBone & ARP Series: Upgrade to DogBone, ARP 2000, or ARP 625 studs for extreme performance builds.
