Features
- 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 bearings and 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
