About the SuperRail

A SuperRail kit is the rail base your fifth-wheel hitch mounts to — not the hitch itself. What makes it a SuperRail is Clean Bed Technology: when you're not towing, you unpin the hitch, unpin the rails, give the mounting posts a twist, and lift the whole thing out. That leaves you a flat, fully usable truck bed instead of fixed rails you have to work around.

Every SuperRail kit is cut to fit your exact truck, so the rails sit where they belong and the hardware lines up the way it should. Pick the kit that matches your truck and bed, then pair it with the PullRite hitch built for it — the finder sorts out which kit and which hitch fit your setup. American-made, every one.

About This Model

This SuperRail base fits the 2011-2019 GM 2500 and 3500. Custom brackets bolt to factory points with no drilling, and the rails carry a 20,000 lbs rating. It's built for the Traditional Series SuperGlide #4400, which drops straight onto the rails once the base is in.

The removable rails work the way the SuperRail line story above describes, so you get a clean bed when the hitch comes out.
