Custom-fit ISR rails for the 2016-2019 GM 2500/3500. Bolt them in, then run any PullRite ISR fifth-wheel hitch up to 20,000 lbs.
Important Notice
Built specifically for 2016-2019 GM 2500 and 3500 trucks. Confirm your exact truck and year in the fitment finder before you buy.
A custom mounting rail kit is the rail base your fifth-wheel hitch bolts to. It is not the hitch — once it's installed, you have a set of mounting rails in the bed, and the matching PullRite hitch drops onto them.
What sets these apart from a universal kit is the brackets. Instead of generic hardware, PullRite cuts the Heavy Duty Custom Mounting Brackets to fit your truck's make and model, so they line up with the points already there. That means less drilling and a quicker install than the brackets most brands hand you. Pick the kit that matches your truck, bolt in the rails, then add the PullRite hitch built for them. American-made.
This kit is the rail base your fifth-wheel hitch bolts to on a 2016-2019 GM 2500 or 3500. The brackets are cut for that truck's frame, so they line up with the factory mounting points and the rails sit where they should over the axle. Once they're in, you have a set of Industry Standard Rails (ISR) rated to 20,000 lbs.
Pair it with a SuperGlide, Super 5th, or SuperLite hitch of equal or lower capacity. Install instructions ship with the kit (see the "2762 ISR Chevy Install" guide).
