SuperRail ISR rail base for the 2020-present GM 2500/3500. Bolt it in, then run any PullRite ISR fifth-wheel hitch up to 24,000 lbs.
Important Notice
Built specifically for 2020-present 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 kit is the SuperRail base your fifth-wheel hitch bolts to on a 2020-present GM 2500 or 3500. The custom mounting brackets are cut for that truck, so they line up with the factory points and go in with no drilling. Once they're set, you have a set of Industry Standard Rails (ISR) rated to 24,000 lbs — pair it with a SuperGlide, Super 5th, or SuperLite hitch of equal or lower capacity.
