Compatible with virtually all CURT 5th wheel trailer hitches as well as many competitors, this set ensures versatility and reliability in your towing setup.
Installed with high-strength hardware, the CURT 5th wheel base rails make mounting your new 5th wheel hitch a breeze. The included mounting bolts, along with two base rails and four universal brackets, ensure a straightforward setup. For those reinvigorating their existing rails, additional 5th wheel base rail bolts and other hardware can also be purchased separately.
Durability is paramount when it comes to towing. That’s why each rail is coated with a specialized dual finish: a co-cured A-coat followed by a tough powder coat. This protective layer defends against corrosion, scratches, and UV damage. Whether you're towing an RV trailer, flatbed, or another heavy-duty trailer, trust that these rails have the resilience needed for the journey.
Rated for a 25,000-pound gross trailer weight, these 5th wheel base rails enable safe and efficient towing. They come in a sleek carbide black finish that not only looks great but also adds an extra layer of endurance for challenging environments. Rest assured that your 5th wheel trailer hitch will remain securely attached in your truck bed, carrying you confidently wherever your horizon leads.
Backed by a limited lifetime warranty with one-year coverage on the finish and parts, you can trust in the long-term performance of these 5th wheel base rails. Investing in the CURT 5th Wheel Bracket Kit along with these base rails guarantees a dependable mounting process for your 5th wheel hitch.
