Clevite Main Bearing Set

This Clevite Main Bearing Set features a 0.020 inch undersize. Main bearings are critical for supporting the crankshaft and maintaining proper oil clearance within the engine block. When rebuilding or repairing an engine, ensuring these bearings are precisely sized and well-built is key to a healthy, long-lasting powerplant. Clevite has been a trusted name in engine bearings for a long time, and this set is made to meet those standards.

The 0.020 inch undersize specification means these bearings are intended for crankshafts that have been machined down by that amount to correct for wear or damage. Proper installation is crucial; these bearings must be installed into a clean engine block and crankshaft, with the correct oil clearance maintained according to manufacturer specifications. Using the right bearings helps ensure the crankshaft spins freely while being adequately supported, which is essential for smooth engine operation and preventing premature wear.
