Clevite Main Bearings Undersize

Clevite undersize main bearings are engine crankshaft main bearings. They are made for engines with a reground or machined crankshaft. They support the crankshaft and keep it turning smoothly in the block. Undersize bearings are also called under-size main bearing sets. They restore correct oil clearance after the crankshaft journals have been ground.

Key Features:

• Made for rebuilds with ground crankshaft journals, so oil clearance can be restored to specification
• Clevite is a long-established engine bearing brand, widely used in engine rebuilding and performance applications
• Precision-manufactured bearing shells made for consistent fit and durable service
• Surface materials and construction are chosen to resist wear and fatigue under load
• Made to help keep oil flow and pressure at the main journals during normal operation

Measure your crankshaft journals and confirm the correct bearing size before installation. Check oil clearance and follow the engine manufacturer's assembly procedures. Clevite main bearings are a dependable choice for a complete engine rebuild or crankshaft refresh.
