ACL Bearings 7M2428H-.25 Race Series Main Bearings 0.25mm Undersize

The ACL Bearings 7M2428H-.25 Race Series main bearings are engineered for high-performance and racing applications where durability and precision are critical. These main bearings feature a 0.25mm undersize specification, designed for use with crankshafts that have been machined or require tighter clearances for optimal performance.

Key Features:

• Race Series construction for enhanced durability under extreme conditions
• 0.25mm undersize dimensions for precision fitment on modified crankshafts
• High-quality bearing material with superior load capacity
• Engineered clearances for optimal oil flow and heat dissipation
• Designed for competition and high-performance street applications

ACL Race Series bearings are manufactured to strict tolerances and use advanced materials to withstand the demanding conditions of high-RPM operation, increased cylinder pressures, and extreme temperatures. The undersize specification allows engine builders to restore proper bearing clearances when crankshaft journals have been ground during rebuilds or performance modifications.
