Torklift SuperHitch Original vs Magnum Receiver & Parts Guide

When towing behind a slide-in truck camper, a conventional single receiver may not provide enough room for the camper overhang or for a correctly rated extension. Torklift's SuperHitch Original 20K and SuperHitch Magnum 30K are frame-mounted, dual-receiver hitches built for specific truck applications. Although they look similar, the receiver openings, hitch part numbers, towing ratings and matching camper tie-down hardware are not identical.

Original 20K vs Magnum 30K

The 20K and 30K family names do not establish the permitted towing load for every installation. Use the weight-carrying or weight-distribution rating stated for the exact hitch and any extension, and never exceed the smallest capacity among the vehicle, hitch, extension, coupler and towing equipment. The Magnum 30K family has a larger upper opening, but its lower receiver remains 2 inches.

Find a receiver by manufacturer part number

These part-number links represent individual truck applications, not interchangeable hitch assemblies. Even within one brand and model range, truck year, bed configuration, frame layout and existing equipment can change which SuperHitch is correct.

Camper tie-downs and extensions need their own checks

Changing from a factory hitch to a SuperHitch may also change which rear truck-camper tie-down you need. Certain Torklift rear tie-downs mount alongside or integrate with a particular receiver model; for example, manufacturer documentation for the D1108-30 identifies the related R3507 tie-down. Do not use this example to infer fitment for a different hitch. View R3507 rear tie-downs if your exact truck and hitch application calls for them.

For a camper with rear overhang, the SuperTruss guide compares extension lengths from 24 to 60 inches, the corresponding towing limits and matching wiring. A SuperTruss is designed for the appropriate dual-receiver system, not for an ordinary single-receiver hitch. Lateral support chains are structural parts of the installation and do not replace the trailer's safety chains.

What to check before choosing

1. Confirm the truck's exact year, make, model, frame and bed/chassis configuration against the hitch manufacturer's application chart.
2. Determine whether you need an Original 20K or Magnum 30K system, and whether the upper opening matches your ball mount or requires the specified reducer.
3. Measure camper rear overhang with the camper installed and select the properly rated extension for the complete towing setup.
4. Check rear tie-down compatibility with the selected receiver, and compare the precise installation instructions and included hardware for the specific hitch.

Installation instructions and capacities are specific to the part number. If you already own a Torklift hitch, start with its stamped manufacturer number rather than the shape of the cross tube.
