Suspension
Front Suspension



This is an image of the front suspension. On this particular suspension type, it consists of 2 radius rods, a spindle, a trailing arm and a shock with a spring coiled over it.

Rear suspension



This is an image of the rear suspension. It consists of many parts which will be described below.



The rear suspension consists of 2 shock absorbers. This image is the shock typically referred to as the front track shock. It has a spring coiled around it, and is the first to absorb impact from objects.



This is the second shock in the rear suspension. It is the one that takes most of the shock from hitting objects such as drifts or jumps.



This is the hifax, typically called "sliders". It is basically plastic that is installed on the bottom of rails so the track clips are not running on the steel or aluminum that the rails are constructed of.



These are idler wheels. They are bolted onto the rails of the suspension to help prevent wear on the hifax.



This is the track. You have the option of adding studs to a track for added traction on ice. The track is what goes around the suspension and it is what makes the snowmobile move. When installing studs, you need some sort of tunnel protection.



These are the heat exchangers. They contain coolant that cools the engine. I put them in the "suspension" section because on many newer Polaris snowmobiles they are also the tunnel protectors for studs.
