Product Details

If you're looking to rebuild or upgrade the engine in your 2011-2013 Polaris RZR XP 900, this Wiseco forged piston kit is a solid option. This kit is designed to replace the stock piston and offers an 11:1 compression ratio, which can help increase power output for your off-road adventures.

Wiseco has been a leader in performance parts for a long time, and these pistons are built with their forged material. Forging the aluminum makes it stronger and more durable than cast pistons, giving you improved tensile strength and a better strength-to-weight ratio. This means the piston can handle more stress and last longer. Each piston is made for specific 4-stroke engines, ensuring it fits right and performs as intended. The kit comes complete with high-quality piston rings, wrist pin(s), and circlips, so you have the essential components for installation.

These pistons are forged and machined in the USA. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
