DescriptionTop 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.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.This item fits the following vehicle applications:compatible with Yamaha YFM700 Grizzly EPS 2018compatible with Yamaha YFM700 Grizzly EPS LE 2016-2018compatible with Yamaha YFM700 Grizzly EPS SE 2018compatible with Yamaha YFM700 Grizzly FI 4x4 Auto 2016compatible with Yamaha YFM700 Grizzly FI 4x4 Auto EPS 2016-2017compatible with Yamaha YFM700 Grizzly FI 4x4 Auto EPS SE 2016-2017compatible with Yamaha YFM700K Kodiak 2016-2018compatible with Yamaha YFM700K Kodiak EPS 2016-2018compatible with Yamaha YFM700K Kodiak EPS SE 2016-2018compatible with Yamaha YXE70 Wolverine 2016-2018compatible with Yamaha YXE70 Wolverine EPS 2017compatible with Yamaha YXE70 Wolverine R-Spec 2016compatible with Yamaha YXE70 Wolverine R-Spec EPS 2016-2018compatible with Yamaha YXE70 Wolverine R-Spec EPS SE 2016-2017
