Product Details

This is a single forged piston from JE Pistons, specifically made for the Polaris RZR XP900. It features a 93mm bore and an 11.0 to 1 compression ratio, designed to give your RZR's engine a noticeable boost in power and responsiveness. If you're looking to rebuild or upgrade your RZR's engine for improved performance, this piston is a solid choice.

JE Pistons are well-known for their robust construction, and this forged piston is no exception. Forging the aluminum creates a stronger, more durable piston that can handle the increased stresses of higher compression and more aggressive riding. This means you can expect reliable performance even when you're pushing your RZR hard. The 11.0 to 1 compression ratio is a popular choice for a good balance between increased power output and pump gas compatibility, though you should always verify fuel requirements for your specific build.

Keep in mind that this piston is not CARB approved and cannot be shipped to California. Always consult your vehicle's service manual or a qualified mechanic for installation procedures and any other components you might need for your engine build.
