ACL Race rod bearings with Calico CT-1 coating use a dry film lubricant that reduces friction and abrasive wear. The coating provides intermittent dry lubrication and is not affected by dust or dirt.
CT-1 is engineered for the demanding conditions of high-performance engines. The bearings offer increased embedability, oil and fuel resistance, and corrosion protection. The set includes ACL Race Series rod bearings with Calico CT-1 coating.
