Custom-fit ISR rails for the 2017-2023 Ford F250/F350 Super Duty. Bolt them in, then run any PullRite ISR fifth-wheel hitch up to 24,000 lbs.
Important Notice
Built specifically for 2017-2023 Ford F250 and F350 Super Duty 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 is the rail base your fifth-wheel hitch bolts to on a 2017-2023 Ford F250 or F350 Super Duty. The Heavy Duty Custom Mounting Brackets are cut for that truck's frame, so they line up with the points already there and the install goes quicker than a universal kit. Once the rails are in, you've got a set of Industry Standard Rails (ISR) rated to 24,000 lbs — pair them with a SuperGlide, Super 5th, or SuperLite hitch of equal or lower capacity.
