P1 | K033-S01S CHRYSLER GEN III HEMI ROCKER STUD KIT - FOR MANTON ROCKER ARM SYSTEM, 12PT NUTS, S220 SERIES, BLACK OXIDE FINS

P1 Chrysler Gen III HEMI Rocker Stud Kit – For Manton Rocker Arm System, 12pt Nuts, S220 Series, Black Oxide
PN# K033-S01S

The P1 Chrysler Gen III HEMI Rocker Stud Kit (PN# K033-S01S) is engineered for high-performance HEMI builds utilising the Manton rocker arm system, delivering exceptional strength, precision, and long-term reliability in extreme valvetrain applications. Designed to handle the demands of high-RPM, high-lift camshafts and aggressive spring pressures, this kit ensures consistent rocker arm alignment and secure torque retention under the toughest conditions.

Manufactured from S220 Series high-strength alloy, each stud delivers an ultimate tensile strength of 220,000 psi, providing unmatched resistance to stretch, fatigue, and high-heat cycles. The premium alloy ensures a higher clamp load than standard hardware, maintaining precise valve geometry and reducing the risk of rocker arm movement during extreme operation.

A durable black oxide finish enhances corrosion resistance while maintaining a clean, professional appearance. The kit includes precision 12-point nuts, engineered for accurate torque application and consistent clamping, completing a valvetrain fastening solution built for serious performance builds.
