CJM x P1 Mfg S220, 14mm Head Stud Kit

Exclusive CJM x P1 Mfg UltraStud - 14mm Head Stud Kit 

Designed by Can-Jam Motorsports, Produced by P1 Manufacturing.

We have partnered with P1 Manufacturing, a leader in Formula 1, NASCAR, and NHRA head stud technology. Their S220 material and high-accuracy heat-treat process produce an exceptionally strong and reliable head stud 

The CJM x P1 MFG 14 mm Head Stud Kit is engineered for high-horsepower Subaru builds that demand absolute reliability. The oversized 14 mm studs offer significantly increased clamping force, helping to prevent cylinder head lift and the head-gasket failures that follow in extreme power applications.

Built for serious performance engines, this kit provides the strength and stability needed when pushing Subaru powerplants far beyond factory limits.

The S220 stud provides equivalent or greater strength compared to ARP 2000, offering a superior option for demanding engine builds.

Their Torque Point™ lube has been carefully developed to reduce clamp-load variation, ensuring consistent and high clamp loads.
