Race Series Construction
Multi-layered tri-metal copper alloy construction combines strength with seizure resistance. Precision manufacturing helps maintain consistent clearances. Design features include extended grooves, increased crush, bearing eccentricity, and enlarged inside-diameter chamfers.
Before Ordering
Confirm the part number, engine application, journal dimensions, groove specification, and required assembled clearance for your build. This listing specifies .001 in. crankshaft undersize, not .001 in. extra oil clearance. Choose bearings based on the crankshaft measurements and your build requirements.
