Namura Technologies NA500196R Piston Ring Set Powersports - 100.44mm

The Namura Technologies NA-50019-6R is a precision-engineered piston ring set sized at 100.44mm, designed for powersports engines including ATVs and UTVs. Each ring set services one piston and is engineered to restore proper compression, oil control, and engine efficiency during top-end rebuilds.

Key Features:

• Gas-nitrided steel top compression ring for superior hardness and wear resistance
• Cast iron second ring acts as a wiper, keeping oil away from the combustion chamber
• Three-piece oil control ring — two scraper rails of highly ductile cast iron or stainless steel alloy with chrome, nitride, or phosphate coating, plus a stainless steel expansion ring
• Compression rings composed of highly ductile cast iron or stainless steel alloy providing excellent wear resistance and a gas-tight seal
• Application-specific design ensures precise fitment and optimal performance for the intended engine
• Meets or exceeds OEM specifications
• Each kit services one piston

Namura Technologies piston rings are engineered with materials carefully matched to each specific application, accounting for cylinder sleeve type, sleeve coating, engine displacement, and engine stroke. The result is a ring set that restores compression, reduces oil consumption, and delivers long-lasting durability in demanding powersports environments.
