Snowmobile enthusiasts, this Ski-Doo tunnel protector kit is essential insurance for your machine! Specifically designed for REV Gen4 and Gen5 models with 137-inch Ice Cobra, Ice Attak XT, or Ice Ripper XT tracks, this kit protects your bulkhead and heat exchangers from damage caused by studs. The patent-pending design gives you proper protection for stud installation on pre-studded tracks, preventing those expensive repairs that can ruin your riding season. Installation is straightforward if you're mechanically inclined, and once it's on, you can ride with confidence knowing your sled's vital components are protected. Whether you're hitting groomed trails or venturing off-piste, this protector ensures your studs do their job without damaging your machine. The quality is exactly what you'd expect from Ski-Doo - durable materials and precise fitment. If you run studded tracks or are planning to add studs, this isn't an accessory - it's a necessity. The peace of mind alone is worth the investment, not to mention potentially saving hundreds in repair costs down the line.
