Hi Bill; are you asking if the Adapter Rails for Curt 5th Wheel Hitch # C88KR will fit the Underbed Rail and Installation Kit for Demco UMS 5th Wheel and Gooseneck Trailer Hitches # DM8551004? If so, the answer is no. There are no adapters that can convert the Demco UMS rails into industry standard rails.
If you're asking if the Adapter Rails for Curt 5th Wheel Hitch # C88KR will fit the puck system in your 2024 Chevy Silverado 2500 the answer is yes, it will. This adapter will allow you to use a 5th wheel hitch that fits ISR rails as long as it is not the B&W Patriot slider or Husky slider.
