The Hot Rods 4430-1 Stroker Crankshaft is a complete, ready-to-install performance replacement for select Polaris 850 ATV applications. Designed as a premier alternative to a costly OEM crankshaft, this assembly includes proven Hot Rods connecting rods, top-end bearings, and crankshaft webs. It is factory assembled and trued to OEM specifications to provide dependable performance, durability, and consistent engine operation.
As a stroker crankshaft, the Hot Rods 4430-1 increases engine stroke for greater displacement and horsepower. It is designed as a drop-in replacement that requires no modification in most applications and uses the stock piston in most installations. The crankshaft is CNC machined and dynamically balanced to accommodate the increased stroke. For additional performance, it can be paired with Cylinder Works Big Bore cylinders to achieve substantial displacement and horsepower gains.
