Description
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.
Additional Note
Namura's Top End kit is ideal for replacing worn parts and making some upgrades. Machined Smooth heads, available for certain models, can increase horsepower and fuel economy while reducing carbon buildup.
