TorkLift SuperTruss 24–60-Inch Extensions: Ratings & Wiring

A truck camper that extends beyond the bumper can leave the trailer coupler too close to the camper. The TorkLift SuperTruss uses a two-member extension with lateral-support chains to move the towing connection rearward when installed with a compatible SuperHitch dual-receiver hitch. Choose the correct length and load rating together; a longer extension is not automatically a higher-capacity one.

How to choose an extension length

Camper already loadedMeasure from the face of the truck's rear bumper to the outside edge of the camper's rear bumper. TorkLift uses that distance as the minimum extension length.
Camper not yet loadedMeasure inside the bed from its front wall to the outside face of the truck bumper. Measure the camper floor length, including front rubber bumpers, through its rear bumper. Subtract the truck measurement from the camper measurement.

Next choose an available length that meets the required reach. The trailer and coupler still need room to turn and move without striking the camper; select and install the system using TorkLift's fitting instructions.

SuperTruss capacity chart by exact MPN

The manufacturer's published figures below show maximum trailer weight / tongue weight in pounds for the listed SuperTruss length when correctly installed with an approved SuperHitch system. The weight-distributing column requires a compatible weight-distribution towing arrangement; do not use its higher figures for ordinary weight-carrying towing.

Part number Extension Weight carrying
Trailer / tongue		 Weight distributing
Trailer / tongue		 Matched 7-way harness
E1524 24 in 7,500 / 750 lb 14,000 / 1,400 lb W6024
E1528 28 in 7,500 / 750 lb 12,000 / 1,200 lb W6028
E1532 32 in 6,500 / 650 lb 12,000 / 1,200 lb W6032
E1536 36 in 6,500 / 650 lb 12,000 / 1,200 lb W6036
E1542 42 in 6,000 / 600 lb 12,000 / 1,200 lb W6042
E1548 48 in 6,000 / 600 lb 12,000 / 1,200 lb W6048
E1560 60 in 5,000 / 500 lb 10,000 / 1,000 lb W6060
Capacity is limited by the weakest rated component. Check the truck's manual, the exact SuperHitch rating, extension, ball mount, trailer hitch, and trailer limits. The ratings shown are not an approval for a standard single-receiver hitch or every factory hitch. Where the manufacturer's guide specifies a minimum extension for a particular SuperHitch installation, that requirement also applies.

SuperTruss versus a regular receiver extender

SuperTruss is designed around the matching upper and lower SuperHitch receiver arrangement and lateral-support chains. It is not a universal single-tube receiver extension. It is also a different product family from TorkLift's Cannon extensions; select by exact hitch and extension model, not by length alone.

Shop SuperTruss extensions in seven lengths

Each card links to the exact MPN listed above. Product availability and included hardware should be confirmed on the individual listing; do not assume the wiring harness is included with the steel extension.

7-way wiring extension part numbers

A longer hitch connection can require a longer trailer wiring run. TorkLift pairs SuperTruss lengths with specific wiring harness numbers; these are separately listed electrical accessories, not alternative hitch extensions. The matching wiring references are shown in the chart, with product links for the harnesses available in our catalog.

Before towing with a camper overhang

  1. Confirm the exact SuperHitch model and that the selected SuperTruss is permitted for it.
  2. Measure the camper overhang and check both hitch reach and trailer turning clearance.
  3. Calculate loaded trailer and tongue weights; use the appropriate weight-carrying or weight-distributing limits.
  4. Follow the manufacturer's instructions for both receiver connections, lateral chains, hitch pins and trailer safety chains.
  5. Check 7-way electrical connection reach, cable routing and operation of all trailer lights and required brakes before travel.

For the truck-mounted receiver, compare our TorkLift C1205, C1211 and C1212 SuperHitch Original 20K guide. If you are also selecting camper anchor hardware, see the Chevrolet/GMC camper tie-down reference. Those are separate components and must be matched independently.
