Race Series Main Bearings to suit Nissan RB25 / RB26 ( 7M2428HC-STD )

Our coated bearings combine ACL’s tough RACE Series lining and overlay metallurgy with Calico’s well renowned CT-1 coating.

CT-1 is a Dry Film Lubricant coating that helps reduce friction and abrasive wear. It provides intermittent dry lubrication and is not affected by dust or dirt. CT-1 is specifically engineered to withstand the extreme conditions of today’s high performance engines. Professional engine builders enjoy a higher level of confidence with increased embeddability, strength and durability.

ACL Race Series performance engine bearings are manufactured to exacting tolerances. Micron tolerance machining supported by precision measurement systems delivers consistent accuracy to key characteristics like wall thickness and crush. This ensures reliable fit and helps maintain consistent clearances.
