Product Description

NEW 6577 ARC Billet Crankshaft  3.100" X 1"  Splined
The ARC Splined Crank utilizes a 10 tooth straight sided spline that creates a much greater load displacing area than a normal keyed crank. No more broken PTO shafts and makes clutch removal a breeze. A must for todays high horsepower Junior Dragsters. CNC machined toughest material ever used for small 4 stroke engines. Features a true 1/8" journal radius for strength and durability. Also feastures airplane wing style counter weights that are proportionaly designed for superior balance. The #6577 crankshaft was designed for aftermarket flathead blocks that have extra spacing between the crank and cam. Will not fit the Briggs Raptor and Blockzilla blocks. Requires splined clutch post and large gear set.
