Key Features:

• Standard size bearings for OE crankshaft journals
• Oil grooves extend around both halves for enhanced lubrication
• Ideal for engine rebuilds with demanding use including heavy duty, motorsports, and street performance applications
• Superior conformability, embedability, and fatigue resistance compared to bi-metal bearings
• Versatile replacement suitable for most OE applications with increased load capacity
