S/S Timing Cover Bolt Kit - 6pt. LS1/LS2

The ARP S/S Timing Cover Bolt Kit - 6pt. LS1/LS2 is a premium fastener solution engineered for GM LS-series engine builders and performance enthusiasts who demand reliability under sustained operating conditions. Built from stainless steel with polished hex-head design, this eight-piece bolt kit addresses a critical weak point in LS engine architecture: the timing cover fastener interface. OEM bolts frequently corrode or loosen due to thermal cycling and vibration, compromising engine sealing integrity. This kit eliminates those failure points through superior material selection and precision manufacturing.

ARP's stainless steel construction resists corrosion far more effectively than factory hardware, particularly in high-heat engine bays or marine/automotive environments where salt exposure accelerates degradation. The six-point hex-head geometry distributes clamping force more evenly across bolt shoulders compared to traditional 12-point designs, reducing the risk of bolt stretch or stripping during installation. Polished finish not only enhances appearance in visible engine compartments but also serves as a visual indicator of bolt condition during maintenance inspections. The kit's lightweight profile (0.4 lbs total) makes it suitable for weight-conscious builds without sacrificing strength or durability, and the compact dimensions ensure seamless integration into tight engine bay layouts typical of LS swap applications.

This timing cover bolt kit is essential for LS1 and LS2 engine builders performing complete rebuilds, restoration projects, or high-performance modifications where OEM fastener reliability is unacceptable. Street and track applications benefit equally from the improved corrosion resistance and consistent clamping force, which prevents oil weeping around the timing cover gasket—a chronic issue in modified LS engines subject to elevated boost or cylinder pressures. Installation is straightforward: remove factory bolts and replace with the ARP kit using standard torque specifications for the engine platform. Compatible with all standard LS1/LS2 timing covers and requires no additional modifications or spacers.
