ACL Race Series Engine Bearings - 5M1633-.75

If you're looking to push the limits of your Nissan Pulsar (1987-2005) or Sentra (1982-2018), the ACL Race Series Engine Bearings are a must-have upgrade for your performance build. These high-performance trimetal bearings are engineered to handle the demands of high RPM conditions, ensuring your engine runs smoothly and efficiently under pressure.

Why Choose ACL Race Series Bearings?

These bearings are designed with a unique combination of advanced metallurgy and engineering, delivering the durability and performance that serious drivers expect. Here’s what sets them apart:

  • High-strength overlay plate with reduced thickness enhances fatigue resistance, allowing for extended performance during high-stress conditions.
  • Hardened steel backs on all rod bearings provide superior support for the bearing lining and help retain the bearings securely in the housing.
  • Increased crush improves bearing retention, ensuring they stay in place even under intense driving conditions.
  • Elimination of flash plating on the back of the bearings enhances heat transfer, maximizing grip between the bearings and their housing.
  • Increased eccentricity compensates for bore distortion at high RPM, aiding in the formation of hydrodynamic oil films for optimal lubrication.
  • 3/4 grooved main bearings optimize load-carrying surface area and oil flow to the connecting rod bearings.
  • Tight and consistent wall tolerances help maintain precise clearances for improved engine performance.
  • Enlarged ID chamfers accommodate larger fillet radii on performance crankshafts, ensuring a proper fit.
