Pacific Performance Engineering Main Stud Kits

PPE main stud kits are engineered to provide superior bottom-end strength and reliability for high-performance diesel and gasoline engines. Manufactured from premium chrome-moly alloy steel and independently tested to deliver over 230,000 psi tensile strength, these main stud kits help secure main bearing caps, maintain precise crankshaft alignment, and reduce the risk of cap walk, bearing wear, and catastrophic engine failure under high horsepower and boost conditions. Each kit features precision centerless-ground, thread-rolled studs with a durable black oxide finish, along with hardened washers, high-strength nuts, and assembly lubricant for accurate torque loading and consistent clamping force. Designed for popular Duramax, Cummins, Power Stroke, and GM LS engine applications, these main stud kits from PPE provide the strength, durability, and confidence demanded by performance enthusiasts, engine builders, and heavy-duty towing applications.
