Clevite Main Bearing Set

This Clevite main bearing set is 0.030 inch undersize, meaning it's designed to fit crankshafts that have been machined down by 0.030 inches during an engine rebuild. Main bearings are critical components that support the crankshaft within the engine block, allowing it to spin smoothly while handling significant loads. When you're rebuilding an engine, especially one that's seen a lot of miles or is being performance-tuned, ensuring you have the right bearings is key to a long-lasting build.

Clevite is a well-known name in engine bearings, and this set is built to support your engine's rotating assembly. The 0.030 inch undersize specification is important because it indicates these bearings are intended for a crankshaft that has been ground down to a specific size to clean up wear or damage. Using the correct undersize bearing ensures a proper fit and oil clearance, which is vital for lubrication and preventing premature wear. This set is suitable for a wide range of Ford and Mercury vehicles from the late 60s through the 90s, including popular models like the Ford Bronco, F-150, and E-Series vans.
