PPE Head Studs - GM, Dodge/RAM, Ford

Engine builders know the importance of strong, precise fasteners for high-performance diesel engines. The PPE Head Stud Kit surpasses industry standards, with center-less ground accuracy and Mil-S-8879 rolled threads for added strength and reduced stress.

Designed for highway, off-road, strip, or street, these Head Studs are recommended for boost levels of 45 psi and above. With a tested tensile strength of over 231,900 psi, they outperform even top manufacturers. Each kit includes hardened washers, nuts, and special assembly grease for uniform load distribution and accurate torque readings.

PPE Main Studs - GM, Dodge/RAM, Ford

Main cap bolts are a crucial component in maintaining crankshaft alignment and ensuring proper seals at the main bearing caps. Stock main cap bolts often yield in performance applications or even in stock conditions as stress cycles cumulate, which can lead to catastrophic engine failure. The PPE Main Stud Kits are designed to address this common failure point.

The PPE Main Studs are constructed of premium chrome-moly alloy with over 215,000 psi yield strength and over 230,000 psi tensile strength. Each stud is heat treated before being centerless ground and thread rolled, which effectively reduces stress concentration and results in a much higher fatigue resistance. Broaching of studs is performed via EDM to ensure top-level precision.
