ARP 230-4301 GM Duramax Head Stud Kit - 6.6L L5P

The ARP 230-4301 head stud kit is engineered specifically for GM Duramax 6.6L L5P diesel engines, providing superior clamping force and reliability for high-performance and heavy-duty applications. Manufactured from ARP2000 material, these studs offer exceptional tensile strength of 220,000 psi, significantly outperforming factory head bolts in durability and resistance to stretching under extreme cylinder pressures.

Key Features:

• ARP2000 alloy construction with 220,000 psi tensile strength for maximum reliability
• Precision CNC-machined threads rolled after heat treatment to prevent fatigue failure
• Optimized for both stock and high-boost forced induction applications
• Allows for even and consistent clamping force across the head gasket surface
• Includes premium-quality parallel-ground washers and ARP Ultra-Torque fastener assembly lubricant
• Designed to be torqued and re-torqued without loss of clamping force

This complete head stud kit is ideal for Duramax L5P owners building engines for increased boost, towing, or racing applications where head gasket sealing is critical. ARP studs eliminate the possibility of head bolt failure and provide a more secure cylinder head-to-block connection than factory torque-to-yield bolts.
