Introducing the Namura Atto-PO595675-33 Top End Rebuild Kit, specifically designed for the Polaris 350L Trail Boss ATV models produced between 1990 and 1994. This comprehensive rebuild kit ensures a perfect fit and efficient functioning of your ATV's engine.

The kit includes all the essential top end components required for a successful engine overhaul.

Additionally, the kit includes a set of new piston pins. These pins are essential for connecting the piston to the connecting rod, enabling the reciprocating motion of the piston. The pins are made from strong, heat-treated steel, ensuring their ability to withstand the rigors of off-road riding.

The Namura Atto-PO595675-33 Top End Rebuild Kit is also equipped with a set of new gaskets. These gaskets are designed to provide a tight seal between the engine components, preventing the loss of coolant, oil, or air and ensuring the efficient functioning of the engine. The gaskets are made from high-quality, heat-resistant materials, ensuring their ability to withstand the extreme temperatures and pressures generated within the engine.

In conclusion, the Namura Atto-PO595675-33 Top End Rebuild Kit is an essential tool for maintaining the performance and reliability of your Polaris 350L Trail Boss ATV. This kit includes all the necessary components required for a successful engine overhaul, including cylinder liners, piston rings, piston pins, and gaskets.
