Polaris 027-720-11 Top End Rebuild Kit for Indy 500 Trail Snowmobiles (86-99) with 72.25mm x 0.25mm Cylinders

The Polaris 027-720-11 Top End Rebuild Kit is specifically designed for the Indy 500 Trail snowmobiles manufactured between 1986 and 1999. This kit comes with all the necessary components required to rebuild the top end of the engine, ensuring optimal performance and longevity.

Included in this comprehensive kit are new piston rings, cylinder compression rings, cylinder scrapers, piston pins, piston pin bushings, cylinder head gaskets, valve guides, valve seals, and valve springs. Each component is meticulously engineered to restore your engine to factory specifications and provide reliable operation in even the most challenging snow conditions.

The piston rings in this kit are designed to provide a snug fit in the cylinder bore, minimizing blow-by and maximizing compression. The cylinder compression rings, on the other hand, ensure efficient combustion and excellent power output. The cylinder scrapers, which come with this kit, help remove carbon buildup, allowing the engine to burn fuel more efficiently.

The piston pins and piston pin bushings are responsible for maintaining the piston's position within the cylinder, ensuring smooth engine operation. The cylinder head gaskets seal the combustion chamber, preventing coolant and oil from mixing and ensuring proper engine function. The valve guides and valve seals work together to control the flow of air and fuel into the combustion chamber, while the valve springs ensure the proper opening and closing of the engine's valves.

By investing in the Polaris 027-720-11 Top End Rebuild Kit, you can rest assured that your Indy 500 Trail snowmobile will be in top shape, delivering superior performance and dependability on the snow. Whether you're an avid snowmobiler or simply looking to keep your vintage sled in tip-top shape, this kit is an essential investment for any Polaris Indy 500 Trail owner.
