Namura Technologies NA-40006-2 Piston Kit - 0.50mm Oversize to 83.50mm, 8.6:1 Compression

Bore: 83.50mm Compression: 8.6:1 Compression Sizing: 0.50mm OversizeMOS2 (made with Teflon/Molybdenum) Coated Skirts - A rolled on application process provides a fits Bond that is 10 times stronger than other spray on coatings. Benefits include increased heat transfer, reduced friction and helping to eliminate cold seizures. Machined Smooth Heads - Reflects combustion heat and reduces carbon buildup, protecting the top of the piston. Some tests have shown this feature can increase horsepower and fuel economy by up to 6%. Anodized Domes - Increases heat resistance and durability; pistons with anodized domes are 75% stronger than non-anodized pistons. 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.2000-2004 fits YAM YFM400 Big Bear 2x4 2000-2006 fits YAM YFM400 Big Bear 4x4 2007-2012 fits YAM YFM400 Big Bear IRS 4x4 1993-1999 fits YAM YFM400F Kodiak 4x4
