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

Forged pistons are made by shaping aluminum at high temperatures, which creates a stronger and more durable component. This improved strength allows them to withstand higher cylinder pressures and temperatures compared to cast pistons, making them ideal for performance applications.

Can I buy these pistons individually for my RZR XP?

Yes, this listing is for a single JE Ultra Series forged piston. This allows you to purchase only the pistons you need for a specific repair or rebuild, rather than a full set if only one is required.

Why can't this piston be shipped to California?

This piston is not CARB (California Air Resources Board) approved. This means it does not meet California's emissions standards for aftermarket parts, and therefore cannot be legally shipped to or sold within the state of California.
