ACL Rod Bearings BMW E9X M3 S65

Designed specifically for the BMW S65B40 engine, our Custom ACL Race Rod Bearing Set is engineered to achieve an ideal bearing clearance of 0.0023"–0.0025". Unlike OEM BMW and standard ACL Race bearings, which typically run tighter clearances, our proprietary sizing delivers improved oil film stability and reliability for performance and rebuilt engines.

Manufactured from genuine ACL Race Series bearings, this set offers exceptional wall thickness consistency, increased bearing retention, and enhanced eccentricity for improved lubrication and protection under high-RPM operation.
