Product Description
This surplus OEM main bearing is designed to support the engine's crankshaft while providing a smooth, low-friction surface for rotation under heavy loads. As a critical component of the engine's bottom end, the main bearing helps maintain precise crankshaft alignment, reduce friction and wear, and ensure proper oil clearance for reliable lubrication. This helps protect the crankshaft and engine block from premature wear while promoting smooth engine operation and long service life.
- Item is in new old stock condition. Bearings have minor surface rust.
