Namura Top end kits are made of high-quality components especially the MOS2 (Teflon/Molybdenum) coated skirts that is 10x stronger than other coatings! Namura top end kits also use a hypereutectic casting process, that provides higher silicon content for reduced expansion rates and additional wear resistance; it also has an ability to withstand higher cylinder temperatures.

Features
- Top End kit includes: piston, rings, wrist pin, clips, top end bearing, and gasket kit
- MOS2 (Teflon/Molybdenum) Coated Skirts - A rolled on application process provides a bond that is 10 times stronger than other spray on coatings. Benefits include increased heat transfer, reduced friction and helping to eliminate cold seizures
- Hyperdryve pistons are composed of a new hypereutectic aluminum alloy developed for use in the space industry
- Engineered to maintain its high tensile strength up to 700�F
- This revolutionary alloy, combined with our already existing features of machined smooth anodized heads (for better heat reflection) & MOS2 coated skirts (giving you smoother startups & break ins) meets the demands of today's 4-stroke engines.
- Hypereutectic Casting Process - Provides higher silicon content for reduced expansion rates and additional wear resistance; it also has an ability to withstand higher cylinder temperatures
- Piston Size: 94.95mm
