Chevy S/S W/P Pulley Bolt Kit

The ARP 430-6802 Chevy Stainless Steel Water Pump Pulley Bolt Kit is designed for small-block and big-block Chevrolet engine builders who prioritize reliability in high-RPM environments. This kit is essential for those who modify their engines or use forced induction, as water pump pulley bolts are subject to significant stress from engine vibrations and thermal cycling.

By replacing factory fasteners with premium ARP hardware, this kit helps prevent bolt stretch and loosening, which can lead to coolant system failures. The bolts are made from high-quality stainless steel, offering superior tensile strength and corrosion resistance compared to OEM bolts. This ensures that the fasteners maintain their clamping force even through repeated heat cycles.

This bolt kit is ideal for anyone rebuilding or modifying a Chevy engine, from street performance enthusiasts to serious racing teams. Its lightweight design, weighing just 0.16 lbs, has no negative impact on engine balance or accessory drive function, making it a practical upgrade for both street and race applications.
