View E1524 productTorklift SuperTruss Hitch Extensions: Length, Towing Ratings & Parts
A truck camper that overhangs the truck's rear bumper may require extra distance between the receiver and a trailer coupler. The Torklift SuperTruss is a dual-tube hitch extension built for compatible Torklift SuperHitch dual-receiver systems. Choose its length by the actual camper overhang, and compare the trailer and tongue-weight ratings for your entire towing setup.
Manufacturer length and capacity reference
The Torklift SuperTruss official capacity chart lists trailer and tongue limits for every length. Torklift's illustrated installation instructions show the upper and lower tubes, lateral chains, collars, shackles and adjustment points.
The ratings below apply under Torklift's specified SuperHitch Original 20K or SuperHitch Magnum 30K conditions. A SuperHitch Hero or other configuration may have different ratings. Always check the manual for your actual hitch.

Why the two rating columns matter
Weight carrying is the limit when towing without a weight-distributing hitch. The higher ratings apply only with a compatible, correctly adjusted weight-distribution system. For example, E1524 permits a maximum 7,500 lb trailer / 750 lb tongue in weight-carrying use, or 14,000 lb trailer / 1,400 lb tongue under the specified weight-distributing arrangement. E1560 at 60 inches is rated 5,000 / 500 lb without weight distribution, or 10,000 / 1,000 lb with it.
Use the lowest relevant rating of the truck, receiver, extension, ball mount, coupler, trailer and weight-distribution equipment. The extension does not increase your truck's towing, payload or combined-weight limits. Verify the receiver family and any installed adapter before ordering.

Measure the length you need
With the camper installed, measure from the face of the truck's rear bumper to the outer edge of the camper's rear bumper. This provides Torklift's minimum extension length measurement. Without the camper installed, measure from the inside front of the truck bed to the outside face of the truck's rear bumper, then subtract that from the camper floor length measured from its front rubber bumpers to its outside rear edge.
Allow for turning and trailer clearance, then select the shortest approved SuperTruss that meets your installation's measured requirements. Do not cut, drill or modify an extension to alter its length.
Assembly, chains and installation checks
The SuperTruss assembly uses an upper receiver tube, lower compression tube, clamp collars, bolts and lateral-support safety chains with shackles and eye-to-eye turnbuckles. Short and long extensions use different hardware quantities. The lateral chains must be installed and correctly tensioned: they are structural support for the extension, not substitutes for the trailer's own safety chains.
Follow the manufacturer's exact collar and fastener instructions. Torklift notes that some SuperHitch Magnum installations require a reducer sleeve, and certain hitch configurations require longer extensions to clear the support chains. Never use SuperTruss in a regular single-receiver hitch or a modified non-SuperHitch receiver.
