Race Series Construction
Multi-layered tri-metal copper alloy construction combines strength with seizure resistance. Precision manufacturing helps maintain consistent clearances, while design features include extended grooves, increased crush, bearing eccentricity, and enlarged inside-diameter chamfers.
Before Ordering
Confirm the part number, engine application, journal dimensions, and required assembled clearance for your build. This listing is for the standard-size 5M429H-STD set. Extra oil clearance is not the same as a crankshaft undersize.
