Custom-fit ISR rails for the 2023-present Ford F250/F350 (aluminum bed). Bolt them in, then run any PullRite ISR fifth-wheel hitch up to 20,000 lbs.
Important Notice
Built specifically for 2023-present Ford F250 and F350 trucks with the aluminum bed. Earlier aluminum-bed Super Duty trucks take the #2766 kit instead — confirm your exact truck, year, and bed 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 2023-present Ford F250 or F350 with the aluminum bed. The brackets are cut for that truck's frame, so they meet up with the factory mounting points and the install goes in with no drilling. Once the rails are in, you have a set of Industry Standard Rails (ISR) rated to 20,000 lbs — drop on a SuperGlide, Super 5th, or SuperLite hitch of equal or lower capacity.
