What is a stroker crankshaft and how does it improve performance?

A stroker crankshaft has a longer stroke than a stock crankshaft. This increased stroke effectively increases the engine's displacement, allowing it to burn more fuel and air with each cycle. More fuel and air means more power and torque, giving your ATV a noticeable boost in performance.

Does this crankshaft come with everything needed for installation?

Yes, this Hot Rods stroker crankshaft is sold complete and ready for installation. It includes proven Hot Rods connecting rods, top end bearings, and crankshaft webs, all factory assembled and balanced.

Will I need to modify my engine to install this stroker crankshaft?

In most applications, this stroker crankshaft does not require modifications to your engine. It is designed to be used with your stock piston, simplifying the installation process.
