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 is the 20K SuperRail base for the 1999-2010 GM 2500 and 3500. The brackets are cut for this truck and these years, so they bolt straight to the frame and put the rails where they belong. Rated to 20,000 lbs.

It carries the #4400 Traditional Series SuperGlide, the 20K hitch this kit is built for. Drop the SuperGlide onto the rails and you're set. See the SuperRail line above for how the removable rails work.
