Bearing Spacer Set Sbc 400 Cid

The Bearing Spacer Set SBC 400 CID by COMP CAMS is designed for serious small-block Chevrolet builders who require precise crankshaft alignment and reduced bearing wear. This set is essential for those assembling street engines, weekend cruisers, or high-performance rebuilds, as proper bearing spacing is crucial for long-term durability and optimal oil distribution.

This spacer set addresses common challenges in 400 CID applications, where factory tolerances can lead to inadequate crush loads and premature bearing failure. COMP CAMS manufactures these components with a focus on consistency and reliability, ensuring that the spacers control radial clearance between crankshaft journals and bearing bores. This maintains the correct interference fit and ensures uniform load distribution across the engine.

Ideal for rebuilding or upgrading any 400 CID small-block Chevy platform, these precision-machined spacers eliminate guesswork and achieve the exact crush loads specified by COMP CAMS—typically 0.0015 to 0.002 inches of interference per journal. By stabilizing oil wedges within the bearing pocket, they improve film strength under sustained RPM and reduce parasitic friction loss, making them a valuable addition for both professional engine shops and DIY enthusiasts.
