Vortex offers several accessories to maximize your cooler's performance. Mud, sand, snow and rough terrain? No problem! Sold per pair (two wheels plus one axle), this quick-change beach wheel kit will turn your 55-quart or 78-quart Elite Series cooler into a serious off-roading machine. Easy, tool-less on/off installation allows you to go from rolling free to packing neatly in a snap. Unlike other wheeled coolers, there is NO loss of capacity - it's the best of both worlds! You can purchase 1 set to pull your cooler behind you luggage-style or purchase two sets to pull your cooler behind you wagon-style. The 78-quart allows three axles for the ultimate ride! Rely on Vortex for all your cooler accessory needs.
