Installing the Torklift SuperHitch Magnum 30K Hitch Receiver and SuperTruss Receiver Extension

Posted in Product Reviews on August 8, 2017

Now, before you ask, “Why would I want a receiver that is rated to tow much more than my pickup is capable of?” consider that there’s nothing wrong with having that extra capacity. No drawbacks whatsoever, except for a higher cost, but there are several useful advantages. Well, at least with the Torklift SuperHitch Magnum 30K there are, and we don’t know of any others with such a high rating.

Let’s use a pickup truck fitted with a slide-in truck camper as an example. Since larger campers usually require an extension to clear the rear overhang, there’s a lot of leverage and forces involved. With Torklift’s SuperTruss receiver extension sticking out 48 inches (the SuperTruss is available in lengths from 21-60 inches), the Magnum 30K is still rated at 12,000 pounds and 1,200 pounds of tongue weight (with weight distributing). That’s more than what many receivers are rated at without an extension.

Yes, the SuperHitch Magnum 30K costs more than lesser receivers, but it’s also two receivers in one. Sitting lower is a standard 2-inch while the upper is a 2 1/2-inch. For the latter, the Magnum 30K comes with a reducer insert that fits far better than the Ram factory ones do, keeping rattles and movement to a minimum when using a regular 2-inch ball mount in the upper position.

It’s highly unlikely that the Magnum 30K will be the weak link in your towing system, and they it’s available for most common pickups, all without a need for drilling any holes. Strength and quality aside, it will forever bug us that despite all the towing related gizmos we’ve built over the years, we never thought of putting two receiver tubes on top of each other. It’s such a good, simple idea.

If you’ve read this far you’re probably also interested in the other virtues of the Magnum 30K. Here’s how the simple installation went, and what we found along the way.

Bolt-together receivers are nothing new, and shipping them is much easier. When engineered correctly they can also be very, very strong—as is obviously the case with the Magnum 30K. This was also the only receiver we’ve found that bolts on to a late-model Ram Chassis Cab without any drilling.
Part of the extra steps taken to make the Magnum 30K sturdy— the extra material welded to the side plates, where the cross tube bolts to it.
Another nice and strength-inducing touch is the welded-on washers at the hitch pinholes. This helps both with wear and shear forces.
Rather than following the instructions to the letter, you’ll find it much easier to install the cross tube if both side plates are hanging loosely from just a couple of bolts at the top.
All hardware (except for the flat washers, oddly enough) is Grade 8. Mostly 1/2-inch, but also some 7/16-inch to match smaller factory holes. Large, thick “washers” are used in a few places to better distribute the clamping force.
This includes at the two brackets per side that clamp to the bottom frame flange. We thought that there were more than enough fasteners holding the side plates, but apparently not quite enough to satisfy Torklift’s engineers. At this point, the two vertical bolts creating the clamping force are not yet installed.
Having serrations, much like wheel studs, the bolts holding the cross tube must be pressed or hammered in place. Why serrated bolts? To eliminate any potential torsional movement of the cross tube is our guess.
Tighten and torque all 28(!) bolts to spec, then go find something heavy to tow. Or, find a washer. Whatever you do, do not drop a lock washer down between the tank and skidplate. The likelihood of that happening is directly proportional to how full the tank is. Yep, ours was full so it took a while before it was feasible to drop the skidplate and retrieve the washer.
Here’s the only opportunity we know of to use two BOLT locks (which adapt to work with your truck’s ignition key) on one receiver. One thing we’re not crazy about is that the receiver tubes are angled up about 2.5 degrees, supposedly to help with the departure angle when using long extensions. It’s not noticeable until a ball mount or pintle hook is installed, but then it looks a bit odd.
