Namura Technologies Piston Ring

Namura Technologies piston rings, also sold as piston ring sets or ring kits, are replacement engine rings for powersports engines. Namura has been making pistons, rings and accessories from its Minnesota headquarters since 2001. Its rings are intended to restore compression and seal the combustion chamber on worn engines.

Key Features:

• Compression rings are made from ductile cast iron or a stainless steel alloy. Both materials resist wear and help create a gas-tight seal.
• Chrome, phosphate or nitride coatings are used where the application calls for them.
• Three-piece oil ring design. Two scraper rails work with a stainless steel expansion ring to control oil on the cylinder wall.
• Each ring set is engineered for its specific application, with the material and fit matched to the engine.
• Made in Taiwan.
• Rings are made to Japanese specifications.

Whether you are rebuilding a top end or freshening a worn engine, Namura piston rings help restore compression, engine efficiency and durability. Select the child item that matches your engine's bore and application.
