Coated Cam Bearing SBC 2.120 +.010

The Coated Cam Bearing SBC 2.120 +.010 from DART is a precision-engineered component designed for small-block Chevrolet engine builders and high-performance enthusiasts who demand reliability in demanding applications. This cam bearing serves as the critical pivot point where your camshaft rotates, and any wear or inadequate coating compromises valve timing precision and overall engine efficiency.

DART's reputation in the racing and performance engine market stems from their commitment to manufacturing bearings that withstand sustained RPM and load cycles that stock components simply cannot handle. This bearing features a proprietary coated surface that reduces friction and extends service life compared to uncoated alternatives, particularly critical when running aggressive cam profiles, high-lift valvetrain components, or extended power bands beyond factory specifications.

Serious small-block Chevrolet builders—whether assembling a 350, 383, or stroker variant—recognize that overlooking bearing quality directly impacts camshaft longevity and overall powerplant durability. The 2.120-inch bore diameter with +.010-inch oversize tolerance accommodates worn or reamed cam journals, allowing you to restore proper clearance without complete block rework.
