Hawks Motorsports offers our clients this 234-3603 LSA 6.2L Supercharged Head Bolt Kit, ARP2000 6-Point Hex Head, Black Oxide, ARP for GM LSA 6.2L supercharged engine applications. This Pro Series cylinder head bolt kit is specifically designed for the LSA engine and includes ARP2000 fasteners with a 6-point hex head, black oxide finish, and hardened parallel-ground washers for even load distribution and accurate torque readings.

If you're pulling the heads on an LSA, this is the kind of hardware you want going back into the engine. Whether you're freshening up a CTS-V, building a Camaro ZL1, or putting together an LSA performance build, upgrading the head fasteners is part of doing the job right. These ARP bolts are built for the kind of cylinder pressure an LSA can make, giving your engine build serious performance-grade hardware where it matters.

The 234-3603 kit uses ARP2000 material and is rated at 190,000 psi tensile strength by ARP product references. The bolts are cold-forged, heat-treated before thread rolling and machining, and supplied with hardened parallel-ground washers. The kit contains 30 bolts and is intended specifically for the GM LSA 6.2L supercharged engine.
