The Reese Kwik-Slide, slides a full 10-inches with the fifth wheel attached to allow for a greater turning radius during low speed maneuvering. This slider is designed for shortbed trucks to prevent damage to truck and trailer in tight spaces. For low-speed maneuvering simply release the high-leverage handle, set your trailer brakes and pull forward to slide it into position. It is compatible with Reese base rails and fits both 15K and 16K model fifth wheel hitches.
