What is a stroker crankshaft and what does it do?

A stroker crankshaft increases the engine's displacement by altering the stroke length. This generally results in more torque and horsepower because the engine can burn more fuel-air mixture with each revolution.

Does this crankshaft come with everything I need for installation?

This Hot Rods stroker crankshaft is sold complete and includes proven connecting rods, top end bearings, and crankshaft webs. However, you may need additional items like gaskets and seals, which are not included.

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

For most applications, this crankshaft does not require modifications and can be used with your stock piston. It's always recommended to consult your vehicle's service manual for specific installation details.
