                Callie's solid modeling abilities provide a great  advantage in product  development. They’re able to precisely locate  material where it will  yield the greatest advantage in terms of both  strength to weight, and  balance ability.

    Beginning with properly placed counterweights that not only improve balance but reduce bearing loads, every aspect of these highly stressed components has been analyzed. The forgings are rough machined in a process that includes double stress relief operations that make these crankshafts very dimensionally stable.

    Hardened with a deep nitride, Compstar cranks are ideal for all types of abusive racing environments. All rod journals are drilled and counterweights are profiled for piston clearance. With a consistent grind and polish, along with precise stroke and index, you will see why we say these crankshafts are Compstar Correct!

    Speedway introduces forged rotating assemblies, with an optional balance job. Includes new 2-pc rear main seal crank, rods and pistons. Cranks are new so they use standard size bearings.

    All Scat 4340 cranks are 2-piece rear main seal, internally balanced and weigh approximately 51-55 lbs.  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. These rotating assembly engine rebuild kits may require additional charges for heavy metal.

    If you are going to run this crank in a sprint car motor, you must have the crank flange turned down prior to balancing the crank to allow it to go through the motor plate. 

    NOTE: A balance rotating assembly option is currently not offered for this package but the proper balancing service can be determined after your order is placed.  If you would like our balancing option service for 395 and 421 engine builds, please call 1-800-979-0122 when placing order.

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