This includes Main, Rod and Thrust Washers. Save more purchasing as a package. If you need individual bearings, please call or email us. email@example.com or 908-275-8560
- Designed to withstand higher RPM conditions.
- 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 conrod 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.
What is the maximum power rating of ACL Race Series bearings?The power rating of the engine can be tweaked in many ways that have correspondingly different effects on the load and stress borne by the bearings. All the methods below affect bearing loading:
- Increasing red line engine speed
- Increasing turbo boost / cylinder pressure
- Changed timing & cam profiles
- Using low viscosity oils and/or high engine temperatures
- Changing crankshaft / connecting rod / piston design
- Modifying cylinder dimensions (boring out, stroking, decking cylinder head)
