BBC Main Stud Kit w/Windage Tray

The BBC Main Stud Kit w/Windage Tray is an essential upgrade for big-block Chevrolet engine builds that require enhanced reliability under extreme load conditions. This kit is ideal for builders working on high-performance street engines, race engines, or restoring classic muscle cars.

Designed to replace factory bolts, the main studs provide superior clamping force to prevent crankshaft movement during peak combustion pressure. Made from high-strength alloy steel, the studs feature precise thread geometry and controlled preload specifications, ensuring a secure fit. The included windage tray helps eliminate oil slosh in the pan, improving cooling and horsepower efficiency.

This kit is particularly beneficial for serious builders, machine shops, and vintage race teams working with BBC engine sizes of 396, 427, and 454 cubic inches. Proper installation requires following torque sequencing and using ARP fastener lubricant to maintain consistent clamp load across all studs, ensuring optimal performance.
