ARP 4300202 GM Duramax LLY-LMM Stainless Steel Head Stud Kit - 6.6L

The ARP 4300202 head stud kit is engineered specifically for 2004.5-2007 GM Duramax LLY and LMM 6.6L diesel engines. This premium fastener solution delivers the clamping force and reliability needed for high-performance and heavy-duty applications.

Key Features:

• Custom age 625+ stainless steel construction for superior strength and corrosion resistance
• 12-point head design for easier installation and removal in tight engine compartments
• Rated at 200,000 PSI tensile strength for maximum clamping force
• Precision-machined threads rolled after heat treatment to prevent fatigue failure
• Includes premium-quality parallel-ground washers and multi-use ARP Ultra-Torque assembly lubricant
• Prevents head gasket failure in boosted, performance, and towing applications

ARP head studs provide significantly better clamping force than factory torque-to-yield bolts, making them essential for modified engines running higher boost pressures or increased power output. Each kit is manufactured in the USA to ARP's strict quality standards and includes complete installation instructions with proper torque specifications.
