Info

These rotating assembly engine rebuild kits are designed for street use and include Keith Black Hypereutectic pistons, Speedway 5140 I-beam rods, main/rod bearings and a Speedway Cast Steel crankshaft. Rings not included. Journals are standard size.  Includes spacers for main bearings.

Due to larger journal side radius on this aftermarket crankshaft, you must use Clevite H-series, King bearings (included in kit) or equivalent.

These assemblies will require balancing either by us or your machine shop.

All balancing is done with our state-of-the-art Hines balancer by race mechanics with over 30 years of experience!  A kit purchased with the optional balance job will ship in 24-48 hours.
