WISECO PERFORMANCE PISTONS

Wiseco is a leading manufacturer of piston kits, with their specially designed, forged pistons. A forged piston is lighter than a cast piston, thus reducing bearing and stress loads on engines, as well as improving the engine's acceleration potential.
NOTE: Other models available by special order.
