Description

A worn top end on the Polaris IQ 600 snowmobile can cause fading power, poor throttle response and difficult cold starts. Because these engines rely on tight sealing and proper piston fit, refreshing the top-end components often restores the performance riders expect. This Top End Rebuild Kit includes the essential parts needed to bring your 600 CFI engine back to life.

Inside the kit, you’ll find matched piston kits with rings, circlips and wrist pins, along with new needle cage bearings and a complete top-end gasket kit. These components work together to help rebuild compression, reduce friction and improve overall engine response. Riders planning a deeper rebuild often review our IQ 600 full rebuild option for comparison.

If you need installation help or fitment clarification, our FAQ page offers quick guidance. Every parts kit includes our 1-year, no-questions-asked warranty. Full details can be found in our warranty policy. First-time customers can also visit the Help Center for shipping advice and rebuild preparation.
