Top End Repair Kit for Yamaha 700 Grizzly, Kodiak, & Wolverine - Standard Bore 103mm (2016-2018)

The Top End kit includes a piston, rings, wrist pin, clips, top end bearing, and gasket kit. The MOS2 (Teflon/Molybdenum) Coated Skirts utilize a rolled-on application process to create a bond that is 10 times stronger than other spray-on coatings. This coating provides benefits such as increased heat transfer, reduced friction, and helping to prevent cold seizures.

The Machined Smooth Heads reflect combustion heat and reduce carbon buildup, which helps protect the top of the piston. Tests have shown that this feature can increase horsepower and fuel economy by up to 6%.

Anodized Domes are included in the Top End kit to increase heat resistance and durability. Pistons with anodized domes are 75% stronger than non-anodized pistons.

The Hypereutectic Casting Process used in the Top End kit provides a higher silicon content for reduced expansion rates and additional wear resistance. This process also allows the pistons to withstand higher cylinder temperatures.
