ARP Trick Flow Prostock 12pt head stud kit

Forged from 8740 chromoly steel, these ARP Trick Flow Prostock head studs are built to handle the increased cylinder pressures common in performance engine builds. The 12-point nuts offer a more secure and even clamping force compared to standard hex nuts, which is crucial for keeping your cylinder heads sealed under stress.

ARP is well-known for making strong, reliable engine components, and this kit is no exception. The studs are heat-treated and thread-rolled for improved fatigue life and easier installation, ensuring they thread in smoothly without damaging your block's threads. This kit is a solid choice for anyone rebuilding or upgrading their engine's top end, providing the clamping force needed to prevent head gasket leaks.

When installing these studs, it's important to follow ARP's recommended torque-to-yield procedure and use their Ultra-Torque fastener lubricant for best results. This ensures the studs stretch properly to achieve the correct clamping load without over-stressing the material.
