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 is the SuperRail base for the 2007-2019 GM 1500 with the 5'8" short bed. It bolts in to create Traditional Series rails sized for that truck, then the rails unpin and twist out when you want the bed back. The line story above covers how Clean Bed Technology works.
It's built for one hitch: the #3100 Traditional Series SuperGlide, rated to 12,000 lbs. That auto-slide hitch is the reason this base exists, since the GM 1500's 5'8" bed is a super short bed and needs the slider for cab clearance in turns.
