Info

These rotating assembly engine rebuild kits are designed for street use and include Keith Black forged pistons, Scat 4340 Pro-Comp I-beam rods and a Scat 4340 forged crankshaft.

All Scat 4340 cranks are 2-piece rear main seal, internally balanced and weigh approximately 51-55 lbs.

These assemblies will require balancing either by us or your machine shop. All kits can be internally balanced.

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.

Rings and bearings not included. Journals are standard size. Due to larger journal side radius on this aftermarket crankshaft, you must use Clevite H-series, King bearings or equivalent.

NOTE: Piston rings are not included and must be purchased separately.
