Before Installing Your Pro S Piston Set

Proper piston and ring setup matters during engine assembly. Review the REV6 Piston and Ring Installation Guide before installation. You can also use our piston ring gap guide when checking ring clearance.

Looking at a Top End Rebuild?

If your engine work requires a parts package rather than the piston set alone, compare the 2025-2026 Polaris Pro S Top End Rebuild Kit. That kit has its own specified piston and gasket package, so check the exact contents before choosing between the listings.

REV6 Engine Rebuild Option

You can also send your engine core to REV6 for a 2025-2026 Polaris RZR Pro S Engine Rebuild if you want our team to handle the engine rebuild in-house.

Parts Warranty and Support

This piston set carries a 1-year REV6 parts warranty. Talk with REV6 if you need help confirming fitment before ordering.
