Restore Compression and Top-End Performance

If your Polaris XPEDITION has developed low compression, cylinder wear, or piston damage, you don’t always need to rebuild the entire engine. This Complete Top End Rebuild Kit is designed for the 2024-2026 Polaris XPEDITION NorthStar ADV and XP equipped with the ProStar 1000 engine, providing the major components needed to restore top-end performance while keeping a serviceable bottom end in place.

By replacing the cylinder, piston, and sealing components during one repair, you can restore engine performance, reduce oil consumption, and get back on the trail with confidence.

Built for Efficient Engine Repairs

Replacing top-end components together helps reduce repeat labor, improves sealing, and restores engine performance more efficiently than replacing individual worn parts over time. Whether you’re rebuilding your own XPEDITION or servicing a customer’s vehicle, using matched components helps simplify assembly and supports long-term reliability. Every REV6 rebuild kit is backed by a 1-year warranty.
