Wiseco is an American designer and manufacturer of parts for 2-stroke and 4-stroke engines. Wiseco pistons are forged pistons with a microstructure that is exceptionally strong and tough. Wiseco pistons are the result of decades of testing and are designed to be reliable, efficient, and durable. Wiseco pistons are suitable for all types of snowmobiling. Wiseco pistons are also available as part of Northern Sledparts' own, self-designed and ready-made piston replacement kits.

Wiseco pistons are sold as piston kits, which include, in addition to the piston, high-quality piston rings, piston pin, and circlips. Most Wiseco pistons come with a ceramic, friction-reducing coating.
