Important Notice
Fits the 2019-2021 GM 1500 with a super short bed (under 6'). Confirm your exact year and bed length before ordering.
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.
This SuperRail base bolts into the bed of the 2019-2021 GM 1500 and gives you a clean set of Traditional Series rails to drop the #3100 Traditional Series SuperGlide onto. Rated for 12,000 lbs, it matches the #3100 hitch it's built for.
It's cut for super short beds under 6 feet, where cab clearance is tightest and the auto-slide does the most work. See the SuperRail line story above for how the removable rails clear your bed when the hitch comes off.
