BBC Main Stud Kit w/2-Bolt Mains

The BBC Main Stud Kit with 2-Bolt Mains (model 10525) is a crucial upgrade for big-block Chevrolet engine builders and performance enthusiasts. Designed for those looking to enhance their engine's reliability, this kit is particularly beneficial for high-horsepower applications, including stroker, turbo, or supercharger builds.

This kit replaces factory bolts with high-tensile main studs, providing superior clamping force and load distribution across the engine block. The 2-bolt main design is compatible with classic big-block Chevrolet architectures (427, 454, 502 families), addressing critical failure points where standard bolts may stretch or yield under load.

Ideal for engine builders, drag racers, and those performing marine or industrial engine swaps, this kit supports a range of applications. Proper installation with a torque wrench and anti-seize compound is recommended to ensure maximum longevity and uniform load bearing.
