Review SBT Top End Kit 1.0mm Oversized Polaris 777/800 Octane for POLARIS 800 2002–2004

The SBT 60-310-2 Top End Kit is a high-performance upgrade for Polaris snowmobiles with 777/800 octane engines produced between 2002 and 2004. This top end kit is designed to deliver enhanced power, improved throttle response, and increased durability to your snowmobile.

The heart of this kit is its oversized 1.0mm intake and exhaust valves, which are larger than the stock components. These larger valves allow for more air and fuel to flow into the engine, resulting in increased horsepower and torque. The intake valves are made from a high-strength steel alloy for added durability, while the exhaust valves are constructed from a heat-resistant material to withstand the extreme temperatures of the engine.

The SBT 60-310-2 Top End Kit also includes new pistons, rings, and cylinder bore liners. The pistons are designed to provide better compression and cooling, while the rings ensure a tighter seal between the piston and cylinder walls. The cylinder bore liners are machined to a precise fit and provide a smooth surface for the piston to slide on, reducing friction and wear.

Additionally, this kit comes with new valve guides, which are designed to provide better support for the valves and reduce valve float. The valve springs have also been upgraded to provide more consistent valve control and improved throttle response.

The SBT 60-310-2 Top End Kit is a direct replacement for the stock components and is easy to install. It is designed to work seamlessly with your Polaris snowmobile's existing engine management system. This kit is ideal for riders who want to get the most out of their Polaris snowmobile and are looking for a high-performance upgrade.

In summary, the SBT 60-310-2 Top End Kit is a comprehensive upgrade for Polaris snowmobiles with 777/800 octane engines produced between 2002 and 2004. It includes oversized valves, new pistons, rings, cylinder bore liners, valve guides, and valve springs, all designed to provide enhanced power, improved throttle response, and increased durability.
