Header Bolt Kit - GM LT1 6.2L 6pt

The Header Bolt Kit - GM LT1 6.2L 6pt from ARP is an essential fastener upgrade for serious LT1 engine builders and high-performance enthusiasts. This kit is designed to withstand the thermal cycling and combustion pressures that factory hardware cannot handle, making it ideal for those looking to maximize power in GM's 6.2-liter small-block platform.

Manufactured from premium alloy steel, ARP's 6-point fasteners are engineered to maintain clamping load across repeated heat cycles, reducing the risk of header gasket failure and fastener stretch. The six-point design ensures even stress distribution across the fastener shank, which helps prevent galling and ensures consistent torque retention.

This kit is particularly beneficial for engine builders, forced-induction shops, and track-focused mechanics who prioritize reliability during power adders or long-duration dyno pulls. Installation is straightforward—simply replace your factory header fasteners with these ARP units and torque to specification using a calibrated wrench for optimal performance.
