4340 Wedge-Mated Crank/Lightweight Flywheel, Chevy Journals

Engineered for high horsepower engines, whether it’s for off-road, street or race applications. If you’re punishing your motor with hi-revving launches, or sustained RPM exceeding 6500, you’re going to want to take a serious look at this setup.

We start with our Super Race Crankshaft (forged from 4340 Chromoly billet) and pair it with one of our Lightweight Chromoly Flywheels featuring eight 11/32″ dowel pins. Next, they’re machined with a high-tolerance matching taper which delivers maximum contact area for a high-friction conical fit. This ensures superior strength and stability for increased durability and reliability.

NOTE: Once the crank and flywheel are fully assembled and torqued, the fitment is so strong that a special tool is required to separate them later. CB recommends the Ron Lummus Racing Wedge-Mate Flywheel Removal Tool. Endplay shims sold separately.
