What is the advantage of a forged piston over a cast piston?

Forged pistons are made by heating and hammering aluminum into shape, which creates a denser, stronger grain structure. This makes them significantly more durable and resistant to deformation under high cylinder pressures compared to cast pistons.

What does a 12.0 to 1 compression ratio mean for my RZR?

A 12.0 to 1 compression ratio is higher than stock, meaning the air-fuel mixture is compressed more before ignition. This generally leads to increased horsepower and torque, but requires proper engine tuning to avoid detonation.

Can this piston be shipped to California?

No, this piston is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

If you're looking to rebuild or upgrade the engine in your Polaris RZR XP900, a new forged piston is a critical component. This single piston from JE Pistons is designed for a 93mm bore and features a 12.0 to 1 compression ratio, which is a notable bump over stock for improved performance.

JE Pistons are well-known in the performance engine world for their robust construction. This piston is forged, meaning it's made from a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable part than cast pistons, making it ideal for high-performance applications where increased cylinder pressures are common. The 12.0:1 compression ratio is achieved through the piston's dome design, which helps increase the power output of your engine when paired with appropriate tuning.

Keep in mind that this piston is not CARB approved and cannot be shipped to California. For optimal results, ensure your engine is properly tuned to take advantage of the increased compression.
