These are Ferrea dual valve springs for the 2011 and 2012 Polaris RZR XP900. Valve springs are critical for keeping your engine running smoothly, ensuring the valves open and close at the right time.

Ferrea is known for making well-built engine components, and this set of eight springs is no exception. They feature specific outer diameters of 19.05mm and 25.30mm, with inner diameters of 13.95mm and 19.05mm. This dual spring design offers improved stability and control over valve motion, which is important for maintaining performance and preventing valve float under high RPMs or heavy loads. They are designed to be a direct replacement for your stock springs, making installation straightforward for someone familiar with engine work.

If you're rebuilding the top end of your RZR XP900 or looking to improve its engine's reliability and performance, this set of Ferrea valve springs is a solid option. Make sure to refer to your service manual for the correct installation procedure.
