Descripción

Upgrade your fifth wheel towing setup with the Demco 8550022 UMS Series 18K Autoslide Fifth Wheel Hitch. This brand new under-bed mounted hitch is rated for up to 18,000 pounds gross trailer weight and features an automatic sliding mechanism with up to 14 inches of travel, making it especially useful for short-bed trucks where additional cab-to-trailer clearance is needed during tight turns.

Unlike conventional manual slider hitches that require the driver to stop, exit the truck, and manually reposition the hitch, the Demco Autoslide automatically moves the trailer rearward as the truck turns and returns it toward the towing position as the combination straightens.

The UMS under-bed mounting design also allows the hitch to be removed when not in use, leaving the truck bed free and clear of traditional above-bed rails. A compatible vehicle-specific Demco UMS mounting kit is required and sold separately.

Automatic Sliding System

The Demco Autoslide is designed to automatically provide additional cab clearance while maneuvering. Its rack-and-pinion mechanism allows up to 14 inches of travel, eliminating the normal process of manually unlocking and repositioning a conventional slider hitch.

For standard fifth wheel pin boxes, Demco states that no separate locking plate is required to activate the sliding mechanism.

Different pin box designs may have additional requirements, so the trailer's exact pin box should be verified before ordering.

Under-Bed UMS Mounting System

The UMS mounting configuration is designed for owners who want to retain the usefulness of their pickup bed when the fifth wheel hitch is removed.

Once the hitch is removed, the system eliminates the permanent above-bed rails associated with conventional fifth wheel installations, providing a cleaner and more usable truck bed.

Fitment Notice

This is a semi-universal hitch with vehicle-specific mounting requirements. The vehicle list above does not mean the hitch installs directly into every listed truck without additional components.

Before ordering, verify:

  • Exact vehicle year, make and model
  • Truck bed length
  • Required Demco UMS under-bed mounting kit
  • Trailer pin box type
  • Any additional pin box components required
  • Gross trailer weight and loaded pin weight
  • Truck payload, axle and towing capacities
  • Cab-to-trailer clearance

The lowest-rated component in the complete truck, mounting system, hitch and trailer combination determines the maximum permissible towing capacity.

Installation Notes

  • Vehicle-specific under-bed mounting kit required
  • Mounting hardware is not included with the hitch itself
  • Professional installation is recommended
  • Verify all required mounting components before ordering
  • Follow Demco installation and torque specifications
  • Adjust hitch height to maintain proper trailer attitude and bed-rail clearance
  • Verify cab-to-trailer clearance throughout the full turning range
  • Recheck mounting hardware according to the manufacturer's maintenance schedule

Warranty

  • Limited 5-Year Warranty
