SuperRail ISR base for the 1999-2010 GM 2500/3500, rated to 18,000 lbs. Bolts in, then any PullRite ISR hitch up to that drops on — and the rails twist out for a clean bed.
Important Notice
Built specifically for 1999-2010 GM 2500 and 3500 trucks. Confirm your exact truck and year in the fitment finder before you buy.
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 kit is the Clean Bed Technology rail base for a 1999-2010 GM 2500 or 3500. It is the base your fifth-wheel hitch bolts to, not the hitch itself. The brackets are cut for that truck's frame so the rails sit where they belong, and once they are in you have a set of Industry Standard Rails (ISR) rated to 18,000 lbs.
Run any PullRite ISR hitch up to that capacity on it — a SuperGlide, Super 5th, or SuperLite. When you want the bed back, unpin the hitch, unpin the rails, twist the posts, and lift it all out. American-made.
