RACE BIG END BEARING SET - std

Designed to withstand higher RPM conditions these race bearings 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 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.
• Tight consistent wall tolerances to help you maintain consistent clearances.

Use with steel cranks COM237 and COM238.
