Stud - Crankshaft Rear Main Seal Retainer

The Chevrolet Performance Stud - Crankshaft Rear Main Seal Retainer (part number 14101058) is a precision-engineered fastener designed for secure assembly of the rear main seal retainer on Chevrolet performance engines. This 1/4-20 threaded stud measures 2.188 inches in length and is manufactured from hardened steel with black oxide finish, providing corrosion resistance and reliable thread engagement in critical engine locations.

The black oxide coating serves dual purposes: protecting against oxidation in the engine bay environment and reducing friction during assembly. The 1/4-20 thread specification ensures compatibility with factory Chevrolet Performance engine blocks and rear main seal retainer housings. At 0.03 lbs, this individual stud is lightweight yet engineered to withstand the vibration and thermal cycling inherent to engine operation. Proper torque application is essential when installing these fasteners to achieve the clamping force necessary for an effective seal without stripping.

This fastener is critical for engine builders, performance shops, and enthusiasts performing rear main seal service or engine block work on Chevrolet Performance platforms. The rear main seal retainer must be secured with the correct fasteners to prevent oil leakage at the crankshaft flange—a failure point that can compromise engine durability if improperly assembled. Ordering individual studs ensures replacement of damaged or stripped fasteners without requiring full retainer hardware kits, reducing downtime and cost during engine rebuild or maintenance intervals.
