ACL Bearings is an Australian manufacturer known for producing precision engine bearings for original-equipment, replacement and high-performance applications. The company has manufactured bearings in Launceston, Tasmania since 1949, developing extensive experience in metallurgy, machining and engine bearing design. ACL’s motorsports involvement dates back to the 1960s, including bearings produced for Brabham Formula 1 engines, and its products have since been used in drag racing, drifting, rally, speedway and touring-car competition. Today, the ACL Race Series is its best-known performance line, offering main bearings, connecting rod bearings, thrust washers and related engine components for a wide range of Japanese, American, European, Australian and Korean engines. This combination of manufacturing history and racing experience has made ACL a trusted choice for professional engine builders and performance enthusiasts.

For Nissan Skyline GT-R and Nissan GT-R applications, ACL offers performance bearing solutions for the RB26DETT used in the R32, R33 and R34 Skyline GT-R, along with the VR38DETT found in the R35 GT-R. ACL Race Series bearings are designed to support stable oil control, accurate bearing clearances and dependable crankshaft operation under the higher cylinder pressures, engine speeds and temperatures produced by modified turbocharged engines. Depending on the application, available features may include tri-metal construction, strengthened overlays, hardened steel backs, optimized oil grooves and tightly controlled wall thicknesses. Select standard-size, undersize and additional-clearance options also give engine builders greater flexibility when setting up an RB26 or VR38 for street, competition or high-horsepower use.
