ACL Race series bearings are precision manufactured to a wall thickness of ±0.0040mm giving engine builders close control of vertical oil clearance.
What is the purpose of ACL Race series bearings?
ACL Race bearings help to, optimise high pressure oil film generation for better bearing load transmission and increased durability. They also help to provide predictable and consistent oil pressure and flow through the engines' oil galleries.
Some benefits of the ACL Race Series Bearings;
Tighter control of bearing clearance, which often leads to improved bearing load transmission and increased durability, this reduces stress on other vital engine components.
ACL race bearings are well proven for their durability and toughness in the most demanding of performance environments.
For Pre A+ and early A+ 1275/1300 engines, Standard size.
