6572-C Manufacturer: ARC SKU: 6572-C Price: $275.00 Quantity:

This crankshaft is machined from a solid bar of Chromoly steel and will give you .175" more stroke than the stock crankshaft with far superior strength. You will need at minimum, our connecting rod #6265 and a Wiseco 10813P2(includes circlips,wrist pin and rings)or larger piston to run this crank. The crank is properly balanced when run with these parts. Other modifications to the engine are up to you.

*The stock bore will need to be honed approximately .004" to fit the piston that goes with this crank. Also, this piston has a thick dome which is designed to be cut down to your engine's deck height. We can pre-cut the piston to standard height and you can use stacked head gaskets of various thicknesses to obtain proper clearances, OR you can test-install the parts and measure to see how much needs to be taken off the top of the piston and have it cut yourself.

*ALL of the compression release components (including the rivets) on the cam must be removed for clearance purposes, but otherwise, the rod and crank are pre-clearanced for this cam. This means that an electric starter will be necessary.

*The only way a non-adjustable flywheel can be used with this crank is WITHOUT a flywheel key.
