The DART BBC Front Main Cap Steel is a precision-engineered component designed specifically for big-block Chevrolet engine builders and performance enthusiasts. This part is essential for those who demand OEM-quality reliability in their builds, whether for street engines, weekend racers, or classic muscle car restorations.

Manufactured from premium steel, the BBC Front Main Cap Steel is designed to work in conjunction with your crankshaft and block to evenly distribute crank loads across the main bearing saddle.
