Ohlins PB662 is a rear shock absorber kit designed for Polaris IQ 440 snowmobiles. It features adjustable compression and rebound damping, allowing you to fine-tune the suspension to your riding style and conditions. The low-speed compression adjuster lets you control the initial plushness of the suspension, while the high-speed compression adjuster helps prevent bottoming out on big hits. The rebound adjuster allows you to control how quickly the suspension rebounds after being compressed, affecting the stability and handling of the snowmobile.
