Chevy S/S Lower Pulley Bolt Kit

The ARP Chevy S/S Lower Pulley Bolt Kit is designed for serious engine builders and performance mechanics who are upgrading or rebuilding Chevy small-block and big-block engines. This dedicated bolt kit is essential for anyone installing aftermarket crankshaft pulleys, balancers, or dampers, as factory bolts cannot match the load-bearing capacity required in high-horsepower applications.

ARP's engineering emphasizes superior tensile strength, precision thread geometry, and consistent clamp load across all fastening points. The bolts are manufactured to exacting tolerances and feature ARP's proven metallurgy, which resists vibration loosening and fatigue failure under continuous high-RPM operation. This design eliminates weak points found in original equipment fasteners, ensuring uniform load distribution and preventing premature wear or failure.

Ideal for engine builders, performance shops, and experienced DIY mechanics, this kit is compatible with Chevy small-block and big-block platforms equipped with upgraded pulley systems. Installation requires standard socket and wrench tools, along with proper torque specifications for optimal performance.
