If you're looking to enhance the performance of your Nissan VG30DETT 3.0L-V6 engine, the ACL 4M2737H-.50 main bearing set is a solid choice. Crafted with a unique blend of design and metallurgy, these bearings are engineered to handle the demands of high RPM conditions, making them suitable for both street and track applications.

Features

  • High strength overlay plate with reduced thickness to improve fatigue properties, ensuring longevity.

  • Elimination of flash plating on the back of the bearings improves heat transfer and maximizes grip between the bearings and their housing.
  • Increased eccentricity compensates for bore distortion at high RPM, aiding in the formation of hydrodynamic oil films.
