CURT – Universal 5th Wheel Base Rails (Gloss Black) (Part No.16104)

Universal 5th Wheel Base Rails (Gloss Black)

from

$139.99
CURT 5th wheel base rails are industry-standard, meaning they can be used with any 5th wheel trailer hitch with industry-standard anchoring points. They are compatible with virtually all CURT 5th wheel trailer hitches and many competitors. Installation of CURT universal 5th wheel base rails is quick and simple. They mount with high-strength hardware, providing a solid mounting place for a new 5th wheel hitch. 5th wheel base rail bolts and other hardware can also be purchased separately to aid in reinstalling used rails. To protect our 5th wheel base rails from corrosion, scratches and UV damage, we coat each one in a co-cured finish of A-coat and powder coat. This gives them the tough skin they need for hauling that RV trailer, flatbed or other heavy-duty trailer and gives you the confidence to tow wherever the horizon leads. This set of 5th wheel rails is rated for 25,000 pound gross trailer weight and has a gloss black finish. Knowing that your 5th wheel trailer hitch is properly mounted in your truck bed is vitally important to the success of your towing. Without a firm attachment point, a 5th wheel hitch is rendered useless to your tow vehicle. When you choose a 5th wheel hitch for your pickup, install it with confidence with a CURT 5th wheel bracket kit and a set of CURT 5th wheel base rails.

Product Features:
  • Helps provide a solid mounting point for a 5th wheel hitch
  • Industry-standard mounting point to accept most 5th wheel hitches

  • Protected by a durable gloss black powder coat finish
