If your engine has higher mileage, don't neglect rod bearing replacement! These bearings are sandwiched between the connecting rod and crankshaft journal and are prone to failure due to overheating, lack of lubrication, or general wear. Replace your rod bearings and prevent a spun bearing.

Starting with ACL’s high-performance bearing shells, our Race Series bearings are built to withstand extreme RPMs and stress. Utilizing a "Duraglide" tri-metal construction and a high-strength overlay plate, these bearings offer superior oiling and heat resistance for high-RPM operation.

Our WPC-treated bearings take ACL’s already impressive design and enhance it even further. The WPC treatment process strengthens and smooths the bearing surface by firing high-speed, ultra-fine particles at the bearing shells, reducing friction and improving durability. This advanced surface treatment ensures smoother operation and improved heat dissipation, which are critical for any high-performance engine.
