TPR017 – Drop In Pistons – Pro R

Fuel your Polaris Pro R engine with the forged TPR drop in pistons, designed to unlock enhanced performance and versatility. Crafted by TPR and manufactured by CP/Arias, these pistons offer a seamless replacement with a range of benefits:

• Options for different compression ratios
• Capability to accommodate larger cams and oversize valves
• Compatibility with race prepped cylinder heads and other aftermarket heads
• Gas ported ring lands and gas nitrated steel rings as standard features

With compression ratio options ranging from OE 12.25-1 to race fuel 13.5-1, these pistons are meticulously designed to optimize the performance of your Pro R engine.

Please note that these pistons are not recommended for use with boost, but stay tuned as we are developing a turbo version to meet your needs.

It’s important to consider the impact of using a ported head with a CNC profiled combustion chamber, as this can significantly affect your target compression ratio. Our 13.5-1 piston, with an increased dome volume of 4.41cc, is tailored to counteract this effect and help you achieve a compression ratio close to stock.

Compatible with the Polaris RZR Pro R 2.0L engine, these drop in pistons are engineered to elevate your driving experience.
