Timing Cover Bolt Kit - 6pt. LS1/LS2

The ARP Timing Cover Bolt Kit for LS1/LS2 engines is a premium fastening solution designed for serious engine builders and high-performance LS platform users. This set of eight chromoly bolts with hex heads and integral washers delivers the critical clamping force and reliability required when securing the timing cover on General Motors' legendary LS-series powerplants. ARP's timing cover bolt kit is engineered to withstand the thermal cycling and vibration loads inherent in forced-induction and high-RPM applications where factory fasteners fall short.

The chromoly construction provides superior tensile strength compared to standard OEM bolts, while the black oxide finish offers corrosion resistance and a professional appearance in engine bay applications. Pre-installed washers eliminate the need for separate hardware sourcing, simplifying the assembly process and ensuring proper load distribution across the timing cover gasket surface. These bolts are torque-to-yield engineered, meaning they reach their design load at specific torque values—critical information for builders working with ARP's published specifications for LS-series engines.

This kit serves engine builders, performance shops, and LS swappers who demand fasteners that won't fail under sustained boost, nitrous, or naturally aspirated high-rev conditions. Whether you're assembling a street machine, track car, or marine application, ARP timing cover bolts are the standard choice when OEM fasteners are identified as a reliability risk. The hex head design works with standard wrench and socket tools, and the complete eight-piece set eliminates the need for partial substitutions or mixed fastener sourcing.
