HOT RODS 4079 Stroker Crankshaft

The HOT RODS 4079 Stroker Crankshaft is a complete, installation-ready alternative to a costly OEM crankshaft. It includes proven Hot Rods connecting rods, top-end bearings, and crankshaft webs, providing a factory-assembled and trued package built to OEM specifications.

Designed with increased stroke for added displacement and horsepower, this crankshaft is a drop-in replacement requiring no modification in most applications. It is CNC machined and dynamically balanced to suit the increased stroke, and it uses the stock piston in most applications. The crankshaft can also be matched with Cylinder Works Big Bore cylinders for significant displacement and horsepower gains.

The HOT RODS 4079 crankshaft is fully rebuildable with genuine Hot Rods connecting rods and bearings. Its gears are manufactured to a quality level of DIN Class 9 or higher. It fits select 2007–2010 Yamaha YFM700G Grizzly Fi 4WD [IRS] and 2014–2016 Yamaha YXM700 Viking and Viking EPS applications.
