Snowmobile Track Information

Snowmobile tracks vary in size and shape depending on their intended use. Improper track selection for certain machines or snow conditions can impair performance and create a safety risk.

Length and Width

Snowmobile track length is measured by circumference. The most common snowmobile track size is 121 inches long and 15 inches wide. Machines designed for passengers or powder snow conditions use longer and wider tracks. Some performance models use narrower tracks. Larger tracks require more engine power to propel.

Paddle Depth

The traction paddles on a snowmobile track can be up to 3 inches long for gaining traction in deep powder conditions. Trail and racing tracks typically use 3/4 inch to 1-1/4 inch paddles. Asphalt racing tracks are smooth and have no paddles.

Paddle Stiffness

Tracks designed specifically for powder use soft paddles that can flex in soft snow. Most other tracks use stiff paddles for maximum traction on firm snow.

Studs

Studded tracks are used in icy or very firm snow conditions. Metal spikes are installed between the paddles to improve acceleration and braking on icy surfaces. The number of studs installed varies based on the need for increased traction and the added weight of the studs.

Driver Pitch

The track pitch is the distance between the inside driver lugs.The most common pitch is 2.52, but other sizes exist. The track pitch must match the snowmobile drive axle pitch.
