Complete Duramax LB7 Head Stud Kit and LB7 Head Gasket KitsThis kit is designed to fit the 2001-2004 Duramax LB7 engine and includes the following:
- LB7 ARP Head Stud Kit (ARP2000)
- Grade C MLS LB7 Head Gaskets by Mahle Motorsports
- LB7 Cylinder Head Gasket Kit by Mahle Motorsports
ARP head studs are cold-forged for molecular uniformity and then heat treated before machining for a clamp load rating of 220,000 psi. With a clamping force greater than factory bolts, ARP head stud kits ensure seal integrity between your cylinder head and engine block to protect against the engine damage that can result from head gasket failure. LB7 ARP Head stud kits also include nuts and hardened washers for even clamping force and accurate torque readings during assembly.
Also included are Grade C LB7 head gaskets from Mahle Motorsport that are 1.05mm thick to compensate for any material removed from the aluminum Duramax cylinder head during resurfacing. Each Mahle LB7 head gasket is manufactured to OEM specifications from multi-layered spring steal. Gaskets are stamped with beading around each combustion chamber to increase sealing pressure and then given additional polymer coatings around the oil and water passages to ensure leak-free performance and a proper seal against micro-imperfections in the head or block surfaces.
Each Duramax LB7 head stud kit also comes with a complete gasket set for every engine component that seals against the cylinder head. The set contains gaskets for the exhaust manifold, up pipe, upper and lower valve cover, along with valve cover grommets, valve seals, and turbo drain seals.
Each Sinister Diesel Heads Up Kit for the LB7 Duramax engines also comes with a complete gasket set for every engine component that seals against the cylinder head including the exhaust manifold, up pipe, upper and lower valve cover, along with valve cover grommets, valve seals, and turbo drain seals.
