BBC Main Stud Kit - Fits 4-Bolt- No Windage Tray

The BBC Main Stud Kit - Fits 4-Bolt - No Windage Tray (ARP 135-5601) is a precision fastening solution designed for big-block Chevrolet engine builders and high-performance mechanics who require exceptional reliability under extreme cylinder pressure. This stud kit is essential for ensuring superior clamping force on 4-bolt main bearing caps, particularly in applications where factory bolts may fail under high-stress conditions such as boost or nitrous oxide use.

Manufactured from premium alloy steel and heat-treated to stringent specifications, ARP studs provide consistent tensile strength and preload retention that surpasses standard fasteners. The kit is specifically designed for engines without a windage tray, simplifying the assembly process and ensuring a perfect fit. ARP's controlled-stretch technology allows for accurate torque-to-yield performance, minimizing the risk of cap distortion or stud fatigue during high-output operation.

This BBC Main Stud Kit is ideal for anyone building a 427, 454, or 502 big-block engine intended for racing, street performance, or marine applications where reliability is critical. Installation requires basic hand tools, making it accessible for both professional mechanics and dedicated enthusiasts.
