Add extra traction to your snowmobile ramp with the 6-foot Black Ice Ramp Extension. Made from high-strength, lightweight aluminum, it is designed to lie flat on the ground to add grip for snowmobile tracks as they prepare to climb the ramp. It can support up to 800 pounds when used properly flat on the ground. Compatible with several of the Black Ice tri-fold ramps, it comes with user-installed stud protectors to prevent rung damage from studded tracks and hooks underneath the lowest rung to eliminate bumps during the loading process.
