Description
Polaris RZR / Ranger 570 Master Engine Rebuild Kit (2018–2022)
If you’re tearing into your Polaris 570 engine, this is the kit that lets you do it right the first time. The REV6 Master Engine Rebuild Kit includes the critical top-end and bottom-end components—plus valves—so you’re not piecing things together or reusing worn parts.
Instead of guessing what to replace, you get a matched set of components designed to work together and restore proper compression, sealing, and reliability.
Why Choose a Master Kit?
A master kit goes further than standard rebuild kits. In addition to pistons and gaskets, it includes intake and exhaust valves—helping you restore the entire valvetrain while the engine is apart.
That means better sealing, improved airflow, and fewer chances of having to tear the engine back down later.
This Kit Includes
- New cylinder
- Oil seal set
- Timing chain
- Oil pump chain
- Crankshaft
- Ball bearings
- Complete gasket kit
- Moly upgraded piston
- (4) Intake valves
- (4) Exhaust valves
Built for DIY Rebuilds
This kit is designed for riders, mechanics, and shops handling their own engine builds. Because all major wear components are included, you can rebuild with confidence instead of mixing old and new parts.
As a result, your engine runs cleaner, holds compression better, and delivers more consistent performance after break-in.

All REV6 parts are backed by a 1-year warranty. If you need help before or during your rebuild, check out our FAQ or contact our team for support.
