CL Race Series performance engine bearings are manufactured to exacting tolerances. Micron tolerance machining supported by precision measurement systems delivers consistent accuracy to key characteristics like wall thickness and crush. This ensures a reliable fit and helps maintain consistent clearances.

• High-strength overlay platewith reduced thickness for improved fatigue properties
• Hardened steel backson all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing.
• Increased crushfor improved bearing retention
• Elimination of flash platingon the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and their housing.
• Increased eccentricityto compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films.
• 3/4 grooved Main Bearingsto optimize bearing load carrying surface area and oil flow to the conrod bearings.
• Tight, consistent wall tolerancesto help you maintain consistent clearances.
• Enlarged ID chamferson bearing edges were required to accommodate a large fillet radius on performance crankshafts.
