Why This Kit Stands Out

This Bottom End Kit consolidates everything you need for a complete crankshaft installation in one box, saving time and reducing mismatch risks during reassembly . According to Hot Rods, these kits give engine builders and weekend mechanics everything needed to do a full bottom end rebuild in one convenient and complete box, ending the frustrating task of searching for part numbers or missing pieces .

The components are precision-engineered to match OEM specifications for smooth operation and reliable longevity . Connecting rods are shot-peened to remove residual stress and create a seamless finish on the crank forgings, ensuring superior dimensional consistency .


Always verify fitment using your machine's exact model, year, and serial number before ordering .
