The ARP BBF Main Stud Kit 12pt. is designed for big-block Ford engine builders and performance mechanics who require reliability under extreme cylinder pressures. This kit is essential for those rebuilding 427, 428, or 429 big-block Ford engines, especially when running high boost, nitrous, or extended RPM levels.
Constructed from premium alloy steel, this kit features precision-manufactured studs and hardened 12-point nuts that enhance clamping force consistency compared to factory bolts. The 12-point nut design allows for six contact points per rotation during installation, which improves torque accuracy and minimizes the risk of fastener galling.
Ideal for high-performance applications, this kit is perfect for builders preparing engines for street performance, drag racing, marine service, or industrial use where main cap integrity is crucial. Each stud is individually packaged and inspected to ensure quality, making it a reliable choice for serious engine builders.
