Lower Main Bearings Only 24pcs. Coated

The Lower Main Bearings Only 24pcs. Coated are essential engine internals designed to support crankshaft rotation and manage critical loads in high-performance and heavy-duty applications. These bearings are crucial for mechanics who are rebuilding engines or upgrading tired powerplants, ensuring that factory bearings are replaced with quality OEM-equivalent options.

Engineered to restore proper clearance and reduce friction, these coated bearings ensure reliable oil film strength during both street and track duty. The tri-metal construction features a steel backing, an intermediate copper-lead alloy, and a hard overlay, creating a protective barrier that resists micro-welding and extends bearing life under stress.

Engine builders, restoration specialists, and performance enthusiasts rebuilding LS, big-block Chevy, small-block Ford, or similarly configured powerplants will rely on this 24-piece set to achieve factory-correct clearance and bearing preload. This set provides complete lower main coverage for full-block rebuilds, ensuring matched bearing geometry and consistent oil clearance specs.
