Expert Take
The Hijacker 21K Autoslide is an above-bed rail-mount auto-slider that clears the cab in turns for short-bed trucks. The combo of rails and auto-slide makes it the fussiest Demco to set up, but it handles 21K and keeps short-bed towing safe at a fair price.

24K SuperGlide
The 24K SuperGlide rail version brings PullRite's automatic short-bed slider to trucks set up with standard rails, self-sliding on turns for full cab clearance. Tows great for 24,000 lbs, but you need the rails installed and the auto-slide head is heavy.

14K SuperGlide
The 14K SuperGlide is the lightest-duty auto-slider, made for short-bed trucks pulling smaller fivers up to 14,000 lbs on standard rails. It self-slides during tight turns to protect the cab and tows quiet; you just need the rails and accept the slider's extra mass.

Frequently Asked Questions
The Demco Hijacker 21K Autoslide Fifth Wheel Hitch (Above-Bed) is rated for 21,000 lbs gross trailer weight (GTW). Always verify your truck's tow rating before purchasing.
This hitch is considered DIY-friendly — most owners can install it with basic tools.
The Demco Hijacker 21K Autoslide Fifth Wheel Hitch (Above-Bed) has a sliding head. For tight, low-speed turns the head moves back toward the tailgate, which moves the pivot point of the trailer away from the cab. That extra clearance is what short-bed trucks need.
This is the 20K Companion configured for industry-standard rails, so it needs rails already bolted in the bed. Once mounted it tows with the same cushioned, articulating head and chucking-free ride as the puck versions.
