Before you start studding your snowmobile track, be sure you have tunnel protection. Snowmobile Tunnel Protector is often comprised of a plastic slide or metal tube affixed to the tunnel’s top.
Buy quality Snowmobile Tunnel Protector from CBMG. They limit the track’s height and provide bottoming-out protection, so the studs do not strike the tunnel. Some sleds have tunnel protection, while others need the installation of a kit.
