Wiseco CS-Type Piston Ring Set

The Wiseco CS-Type Piston Ring Set is a replacement piston ring set made for use with Wiseco forged pistons. These rings are built for powersport engines, including motorcycle, ATV, snowmobile and similar two-stroke and four-stroke applications. They restore ring seal and help the engine make consistent power.

Key Features:

• CS-type design uses chrome-faced, high-temperature steel alloy compression rings with an internal notch
• Made to Wiseco's own specifications to seal well and perform consistently with Wiseco pistons
• Suitable for cast iron, nickel ceramic plated (Nikasil), boron composite and Electrofusion cylinder bores
• Made in the USA
• Model- and bore-size-specific sets, so the ring type matches the piston it goes with

Important Notes:

• For use with Wiseco pistons only. Do not use them with OE or other aftermarket brands of piston.
• The ring type and bore size (in mm) are stamped on the piston dome. Use them to choose the correct replacement rings.
• Ring styles cannot be interchanged.

Wiseco CS-type ring sets are a dependable choice when you rebuild a top end or refresh a Wiseco piston. They help the engine hold compression and keep running reliably, on the trail or at the track.
