Description
Competition exhaust valve for the 2011–2012 Polaris RZR XP900, offering precise dimensional consistency for improved reliability during repeated high-RPM operation.
Manufactured by Ferrea, a recognized supplier of performance valve hardware, this set of four exhaust valves is engineered to the specified head and stem dimensions to maintain consistent valve timing and seating characteristics.
- 33mm head diameter — ensures the intended sealing surface area for the RZR XP900 exhaust valve seat.
- 5.47mm stem diameter — provides the specified fit within the valve guide clearance for consistent valve movement and longevity.
- Set of 4 — complete quantity to service all exhaust valves on the engine when replacing as a set.
- Application — specifically for 2011–2012 Polaris RZR XP900, matching the OEM valve form factor.
Why these details matter:
- Exact head diameter — a correct head size preserves proper combustion sealing and prevents seat leakage that can compromise performance and reliability.
- Specified stem diameter — correct stem sizing maintains designed guide clearance, reducing wear and ensuring repeatable valve motion under load.
- Complete set — replacing all exhaust valves together avoids uneven wear and simplifies valve lash and timing adjustments.
- Ferrea quality — sourcing from an established valve manufacturer supports consistency across parts, aiding predictable engine behavior after installation.
