Product Details

The Terra Alps Racing tunnels for the Mtn Max or Viper chassis. Are designed for aggressive boondocking and hillclimbing. The footing position is kept low to lower your mass weight and centre of balance. This will make it easier for carving and making quick manouvers on the hills. We also changed the foot toe area with an air vented bracket to protect you from blowing a belt. Especially if you have a sled with a drop and roll. The rear section of the tunnels are tapered in so they don't drag in the snow like others. So when your carving it doesn't slow you down.  A better designed tunnel keeps you from less fatigue through out the day.

Tunnels come with a strong grab bumper and snow flap.

Reinforced cooling extrusion on the running boards for extra strength and keeping the footing area clean from ice build up.

Proper tunnel thickness, design and bend radius's keep our tunnels strong and last thru lots of hard riding.
