Features to know about

Solid Foundation for Heavy Towing: Semi-Custom Brackets Provide Secure Mounting

This kit includes semi-custom brackets that mount beneath the truck bed to create strong attachment points for the fifth-wheel rails. The brackets work with your truck’s frame for a tight, dependable connection that can handle the weight and torque of towing a fifth wheel trailer. The setup gives you a sturdy platform for your hitch without major modifications.

Smooth Setup with Complete Hardware: Everything You Need in One Kit

The Curt Semi-Custom Fifth Wheel Installation Kit comes with base rails, semi-custom brackets, and all the mounting hardware you need to get the job done. Since it’s a complete kit, you don’t have to track down extra parts or worry about compatibility between brackets and rails. The included gloss-finish rails sit cleanly in the bed to hold your fifth wheel hitch securely.

Flexible Hitch Compatibility: Industry-Standard Rails Fit Popular Brands

The base rails use the standard fifth-wheel mounting pattern, so they’re compatible with hitches from Curt, Draw-Tite, Hidden Hitch, Reese, Valley, and Husky. That gives you flexibility if you already own a hitch or plan to change brands in the future. It’s a practical setup that keeps your options open no matter which hitch you run.

Clean Look and Strong Finish: Gloss Rails Match Your Hitch

The visible rails have a gloss finish that complements most hitches and gives the bed a finished, factory-style look. The coating also helps protect the rails from scratches and corrosion, keeping your setup looking sharp while standing up to the wear and tear of towing.
