Product Description

The ARP 234-3710 Pro-Series Head Bolt Kit is specifically designed for GM's Gen V 6.2 L LT-series small block engines (LT1 and LT4), where the M8 corner bolts are not used. By replacing the factory torque-to-yield bolts with ARP2000 alloy bolts, this kit greatly improves clamping force, durability, and long-term reliability, especially under high-performance or track conditions.

Cold-forged and heat-treated for maximum strength, these 12-point bolts with wide flanges and hardened washers ensure even load distribution and precise torque control. This makes the kit ideal for performance builds, forced-induction setups, or any application that demands reusable, race-quality head fasteners. Proper installation requires following ARP's recommended torque procedure using the supplied assembly lubricant.
