Custom-fit ISR rails for the 2013-2025 Ram 3500. Bolt them in, then run any PullRite ISR fifth-wheel hitch up to 20,000 lbs.
Important Notice
Built specifically for the 2013-2025 Ram 3500. 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 2013-2025 Ram 3500. The Heavy Duty Custom Mounting Brackets are cut for that truck's frame and line up with the points already there, so the rails sit correctly over the axle and the install goes quick. Once they're in, you've got a set of Industry Standard Rails (ISR) rated to 20,000 lbs.
Pair it with any PullRite ISR hitch of equal or lower capacity — a SuperGlide, Super 5th, or SuperLite. American-built, and rated to carry real weight.
