Before you stud your snowmobile track, you'll need to make sure you have tunnel protection. Tunnel protection normally consists of a plastic slide or aluminum tube that is adhered to the top of the tunnel. What they do is limit the height the track can travel and giving a bottoming out protection so the studs do not hit the tunnel. Some sleds have tunnel protection built in while others require a kit to be installed.
We recommend installing the OEM tunnel protectors for your snowmobile.
