ACL Race Series Performance Engine Bearings
The unique combination of design, metallurgy and engineering come together to deliver what drivers expect from high performance Tri-metal Engine Bearings.
Designed to withstand higher RPM conditions, ACL Race Series Engine Bearings are available for many of the popular 4, 6 & 8 cylinder applications and feature:
- High strength overlay plate with reduced thickness for improved fatigue properties
- Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing.
- Increased crush for improved bearing retention
- Elimination of flash plating on the back of the bearings to improve heat transfer through the bearing sand to maximize the grip between the bearings and its housing.
- Increased eccentricity to compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films.
- 3/4 grooved Main Bearings to optimize bearing load carrying surface area and oil flow to the con-rod bearings.
- Tight consistent wall tolerances to help you maintain consistent clearances.
- Enlarged ID chamfers on bearing edges where required to accommodate large fillet radius on performance crankshafts.
Applications:
4G63/4G64 7-Bolt DSM 2G 7-Bolt and EVO 1-4
