LS Head Bolt Kit - 04-Up (1-Head)

The LS Head Bolt Kit - 04-Up (1-Head) by Brian Tooley Racing is designed for LS engine builders and enthusiasts who require reliable fastening under high cylinder head pressures. This kit is essential for those constructing high-performance street engines, race-prepped long-blocks, or restoring classic models like the fourth-generation Camaro or Corvette.

Engineered to address the limitations of OEM bolts, this kit ensures proper head bolt torque and clamping force, which are critical for maintaining gasket sealing integrity and long-term engine reliability. The fasteners are designed to withstand extreme conditions, including boost, nitrous, and high-RPM operation, while maintaining clamping force through thermal cycling.

Ideal for builders of dual-quad carb LS setups, LSx swap projects, or turbocharged applications, this kit provides the confidence of superior fastener quality. It is compatible with both stock and aftermarket cylinder heads rated for 2004 and later LS variants, ensuring versatility in various engine builds.
