ACL Bearings Race Series Main Standard Size Engine Bearing Kit

The ACL Bearings Race Series main bearing kit is a performance crankshaft main bearing set (also called an engine main bearing kit) for high-output street, track and competition engines. Race Series bearings are made for the loads, RPM and oil film conditions that stock-style bearings are not designed to handle. These kits are supplied in standard size.

Key Features:

• Race-focused design: Built for high-load, high-RPM engines such as forced-induction, nitrous and endurance builds.
• Multi-layer construction: Uses a steel backing with a bearing alloy lining for strength, fatigue resistance and conformability.
• Precision manufacturing: Made to tight dimensional tolerances for consistent crush, fit and oil clearance.
• Standard size: Intended for crankshafts at standard journal dimensions.
• Application-specific kits: Each part number in the product line is made for a specific engine family.

ACL Bearings has a long motorsport heritage, and its bearings are widely used in engine rebuilds and performance builds. For best results, check crankshaft journal size and oil clearance with proper measuring tools during assembly, and follow the engine manufacturer's torque specifications.
