Main Bearing Set Coated Nissan 6-Cyl RB25/RB30

The Main Bearing Set Coated Nissan 6-Cyl RB25/RB30 from ACL Bearings is a precision engine component designed for builders and enthusiasts who demand reliability in high-performance Nissan inline-six applications. This bearing set is ideal for those restoring classic RB-series engines or building turbocharged street machines, providing essential support for the crankshaft.

These coated bearings are specifically engineered for the RB25DE, RB25DET, RB30DE, and RB30ET engine platforms, known for their durability and tuning potential. ACL's innovative coated bearing technology applies a thin, friction-reducing layer to the bearing surface, enhancing load distribution and heat dissipation during operation. This coating minimizes metal-to-metal contact during cold starts and warm-up cycles, extending bearing life in rebuilt or modified engines.

Mechanics and engine builders working on RB25 or RB30 mill rebuilds will appreciate the consistent quality and proven track record of ACL bearings. The -.025 undersizing designation indicates that these bearings are designed for use with slightly re-bored crankshafts, ensuring a proper fitment. This Main Bearing Set includes the necessary components for crankshaft installation, making it a reliable choice for performance applications.
