Clevite MB2580AL30 Main Bearing .030 Oversize

The Clevite MB2580AL30 is a precision-engineered individual main bearing designed for high-performance engine applications. This bearing features an aluminum construction with a .030 inch oversize specification, making it ideal for engine rebuilds where the crankshaft journals have been machined or require additional clearance.

Key Features:

• Tri-metal construction combining steel backing, copper-lead alloy layer, and electroplated babbitt overlay
• .030 inch oversize for machined crankshafts or custom clearance requirements
• Hardened steel back provides superior strength and durability
• Babbitt overlay delivers excellent conformability and reduced friction
• Engineered to exceed OEM standards for high-performance and racing applications
• Compatible with medium to high RPM engine builds

Clevite bearings have set the standard in precision engine components since 1929, offering proven performance in racing and high-performance applications. The aluminum bearing design provides specialized characteristics for specific engine building requirements where traditional tri-metal bearings may not be optimal.
