ACL 5M2964H-.50 Main Bearing Set

The ACL 5M2964H-.50 is a high-performance main bearing set designed specifically for those looking to enhance the durability and efficiency of their Nissan SR20DE/DET engines. These bearings are crafted with a unique blend of design and metallurgy that caters to the demands of high RPM conditions, making them an excellent choice for both street and track applications.

Features
