Build Your KitYou're almost there! This kit has an option or two for you to select. Let us know which options you want for your new kit.
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.
