Polaris Ranger 1000 98mm Big Bore Top End Kit

This Polaris Ranger 1000 Top End 98mm Big Bore Kit fits 2017-2026 models. It gives you the cylinder, forged pistons, and gasket coverage needed when your Ranger top end is ready for more than a basic refresh.

The 98mm big bore cylinder pairs with 98mm forged big bore pistons for a matched top-end parts setup. As a result, shops, mechanics, and hands-on Ranger owners get the main components needed to move the rebuild forward without piecing together the core parts separately.

What This Kit Includes

• 98mm big bore cylinder
• 98mm forged big bore pistons
• Complete top end gasket set
