Description

If your Polaris IQ 600 snowmobile is starting to feel sluggish or run hot, the top end is often the culprit. Worn cylinders, aging pistons and tired bearings can reduce performance and shorten engine life. This Complete Top End Rebuild Kit gives you the high-quality parts needed to restore your engine’s heart.

The kit includes new Nikasil-plated cylinders, matched piston kits with rings, circlips and wrist pins, needle cage bearings, and a full top-end gasket kit. These components combine to restore proper sealing, sharpen throttle response and bring back full trail reliability. Riders often compare this kit with our IQ 600 Engine Rebuild Kit to see which best fits their build.

Designed for cold starts and long trail runs, each part is engineered for winter conditions. Snowmobile riders know that when the top end is refreshed correctly, the sled runs smoother, cooler and stronger. For quick fitment or install questions, visit our FAQ page.

This parts kit includes our 1-year, no-questions-asked warranty. You can review full policy details at our warranty policy. New to ordering?
