Valve Cover Bolt Kit GM LS1/LS2 12pt

The Valve Cover Bolt Kit GM LS1/LS2 12pt from ARP is designed for LS-platform engine builders and performance enthusiasts who require reliable fasteners with superior clamping force. This kit is essential for those assembling high-performance street engines, forced induction builds, or track-focused LS powerplants, addressing common issues with factory valve cover retention.

Manufactured from premium-grade steel alloy, these fasteners are engineered to resist corrosion and ensure long-lasting performance even in harsh engine environments. The 12-point design enhances the contact surface area between the bolt head and wrench, allowing for more even torque distribution and reducing the risk of rounding during installation or removal. This design also permits the use of smaller wrench sizes, enabling finer torque increments for precise control.

Compatible with both LS1 and LS2 engines, this kit is suitable for a variety of applications, including most fourth-generation Corvettes, fifth-generation Camaros, and first-generation CTS-V models, as well as LSx swap projects into older vehicles. Both professional builders and DIY enthusiasts will appreciate the reliability and performance that ARP fasteners provide.
