Scat

It's a fundamental engineering principle that lighter weights of rotating mass means improved engine performance, with better throttle response and quicker buildup to high RPMs. The trick is to develop lighter weight crankshafts that still have the strength and durability you need for extreme conditions and high performance. The team at Scat has been building a name for themselves with their lightweight forged and steel crankshafts for decades.

This is where you can find not only Scat cranks, but full rotating assembly packages: pistons, rods, rod bearings and main bearings. Select kits also include the flexplate and harmonic damper. Rotating assembly kits are designed to eliminate the guesswork from engine building: just QC the parts, wash and they're ready for assembly.

Forged connecting rods and cranks are fabricated from 4340 steel, with your choice of forged or hypereutectic pistons. Cranks are nitride-hardened for durability, with straight-shot oil holes and lighting holes for bearing journals. The end result is cranks and rotating assemblies that are designed to easily handle the power of high-compression, race or street applications. Make Scat crankshafts and Scat performance part of your next engine build and you won't regret it.
