MX5 NA/NB ACL Race Main Bearings (New) (Aftermarket)

ACL Race Series performance engine bearings are meticulously crafted with precision in mind. They are manufactured to exact tolerances, ensuring consistent accuracy in critical characteristics such as wall thickness and crush. This attention to detail guarantees a reliable fit and the maintenance of consistent clearances, contributing to the bearings’ high strength and excellent seizure resistance.

These bearings are designed without flash plating, which not only enhances bearing retention but also maximises heat transfer. Adjusting oil clearances is a common practice, achieved by mixing bearings of adjacent grades. If your crankshaft requires regrinding to an undersize it’s essential to measure the assembled bearing IDs first and then have the required journal sizes ground to match the bearing measurements.
