Product Details

JE Pistons is well-known for making strong engine components, and this single forged piston for your Polaris RZR XP900 is no exception. If you're looking to rebuild or upgrade your RZR's engine, this piston is built to handle the demands of performance riding. It's designed to fit your RZR XP900 with a 93mm bore and a 11.5 to 1 compression ratio, which is a notable bump over stock for improved power.

This piston is forged, meaning it's made from a solid piece of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast ones, making it ideal for high-performance applications where heat and pressure are significant. The 11.5 to 1 compression ratio is a specific tuning choice that raises power output, especially when paired with appropriate engine management and fuel.

Keep in mind that this piston is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
