The #4500 OE Puck Series Heavy Duty SuperGlide is designed specifically for 2020 and newer GM trucks with factory pucks. Accurately tested to exacting SAE J2638 standards, this fifth wheel hitch tows a gross trailer weight of 24K and easily out-performs other foreign-made hitches of the same class. With even beefier components to accommodate heavier loads than the other OE Puck SuperGlides, the 14" of travel quickly and easily moves your trailer away from your cab during turns and backing up with ease! This direct attachment hitch mounts directly to your truck's OE puck mounting points, no rail adapters needed. SuperGlide is the only real solution to safely and efficiently regain that 90º turning capability. It's fully automatic, so there's no getting in and out of your truck to throw levers before and after turns like you have to do with other manual slide hitches. SuperGlide quickly moves your trailer away from your truck cab without you having to do a thing! No anticipation...just get in and drive!
