Video Transcript for TorkLift Wiring Harness Extensions For SuperTruss Hitch Extenders Review

Today we're going to be taking a look at the Torque lift line of wiring harness extensions for use with the super truck hitch extenders. These are available in several different lengths. Just depending on how long that hitch extender that you're using is going to be. This is Torque's Lifts 36" extension that matches their 36" super stress. If you're going with the longer super truss, get the longer. If you're going with the shorter, get the shorter. Really a nice option to where you can plug it right into the back of your vehicle, bring your power down to where it's right here, readily available and accessible for you to get to. What we're going to do is take our, what looks like a trailer plug end, we're going to pass it through our bracket.

It's just flexible enough we can kind of bend that bracket so allow it to come through. Then here's what we want, that's our 7 pole connector. We're going to be bale to hook our trailer up right here. We've got the nice safety chain connections there an then also our wiring connection. Slide that in.

We're pass our screw through the face there and then just put our nuts on the back. Now, the hardware's not provided so you'll need some hardware to pass through there. You can see our bracket's kind of got the oblong holes to make it to where it'll fit a lot of different style harnesses. I'm going to put a flat washer on to give our nut a good surface to bite to when we tighten it down. Now we can go ahead and tighten those down as well. At that point, we're mounted on, got a nice secure connection point.

We can basically just plug this right into the back of our truck. You don't want this to be hanging down underneath our hitch where it might drag or something like that. That will complete today's look at the Torque Lift wiring harness extensions for the super truck hitch extender.

2nd extension I've put on a truck. The first I made my own harness. This time I purchased the TLW6048 and in about 5 minutes the install was completed. No hunting down components this time!


Was delivered earlier than promised. Was what was ordered and Andy C. was very helpful.


Works perfect with the 48" hitch extens ion.


Easy straight forward installation. Fit our 48” SuperTruss extension without issue.


easy well thought out web site. Delivered exactly as promised, maybe even early, (ordered last year), and will use etrailer again!


Worked great no hardware was included with this two way cable to mount to the bracket or came with the extension kit.

  • 7-Way Extensions for 48 inch or 10 Foot for Camper
    To extend a 7-way 48 inches you'd want the part # TLW6048 which comes with a 7-way male on one side and female on the other. If instead you were looking for 10 feet the part # TLW6510 would be what you'd need. These are the best options available for what you are looking for!

  • Available 7-Way Wiring Extensions
    We offer several lengths of 7-way extension such as the 3-foot # TLW6036, the 4-foot TorkLift # TLW6048 and the 10-foot # TLW6510. Each will provide additional slack to allow for a full turning radius.

  • Options for 7-Way Wiring For Truck Bed Camper Shell to Allow Longer Wiring Solution
    10 feet is the longest 5th wheel style of 7-way harness that we offer. If you can find a more direct route to get it up to the front of your truck bed that would be ideal. Otherwise we do have 7-way extensions you could use on the camper like # TLW6021 which is 21 inches or the part # TLW6048 which is 48 inches long.

  • Trailer Hitch Receiver Extension for Ford F-350 With 3" Receiver and Lance Camper
    The TorkLift Cannon Hitch Extension # TLE1648 is a 48" receiver extension. This extension will allow for 300lbs of tongue weight and 3,000lbs towing. If you use a weight distribution hitch the weight capacity is 600lbs of tongue weight and 6,000lbs towing. The TorkLift Wiring Harness Extension for 48" SuperTruss or Cannon Hitch Extender # TLW6048 will extend your trucks 7-way blade trailer connection.

  • Weight of TorkLift TLE1648 48 Inch Cannon Hitch Extension
    The TorkLift # TLE1648 Cannon Hitch Extension weighs in at just over 75 lbs. I've linked to a product description video featuring the Torklift # TLE1648. Along with the hitch extension, you'd also need the # TLW6048 wiring harness extension.

  • Can TorkLift Wiring Extensions for SuperTruss Hitch Extenders Be Shortened
    You could cut and resplice the # TLW6532 7-way wiring harness extension to shorten it, but I'd personally be leery about that as the splices could possibly be vulnerable to the elements and corrosion. The best practice would be to get a harness in the correct length so you don't need to cut it up. TorkLift offers the extensions in the following lengths: • 24 inch, part # TLW6024 • 28 inch, part # TLW6028 • 32 inch, part # TLW6032 • 36 inch, part # TLW6036 • 42 inch, part # TLW6042 • 48...

For example, if you need several feet of additional length we offer the Curt Universal 5th Wheel/Gooseneck 7-Way Extension # C56080 which is 7-feet long. If a shorter extension will suffice you might use the 28-inch TorkLift # TLW6028, 36-inch # TLW6036 or 48-inch # TLW6048. If either your truck or trailer use different connectors (the linked article...

  • Capacity of TorkLift SuperHitch Original TLC1208 w/48" Extension on a 2013 Chevy Silverado 3500
    Yes! With the TorkLift SuperHitch Original # TLC1208 installed on your 2013 Chevy Silverado 3500 and using the 48 inch SuperTruss extension # TLE1548 the hitch will have a capacity of 6,000 pounds gross trailer weight and 600 pounds tongue weight.

  • Frame-Mounted Camper Tie-Downs and Hitch Extender for a TorkLift SuperHitch
    I have a solution for you that will work great with the TorkLift SuperHitch Original Trailer Hitch Receiver item # TLD1100 you referenced but we do not have any spacers. Instead, you will want the TorkLift Custom Frame-Mounted Camper Tie-Downs item # TLR3503. These tie-downs insert inside TorkLift hitches frame mounted brackets. They secure your camper to your truck's base instead of its bed, which better distributes weight to keep setup from being too top-heavy. The TorkLift SuperHitch...

  • Recommended Trailer Hitch With Extension For 2007 Chevrolet Silverado With Camper Installed
    I recommend the TorkLift SuperHitch Original Trailer Hitch Receiver, part # TLC1205 for your Silverado if you have an 8-ft bed on your truck. If you have a 6-1/2 ft bed the hitch I recommend is part # TLC1204. As far as the extension you will need to measure the distance from the hitch pin hole to the end of the camper to see what length extension you will need. We offer different length extensions like part # TLE1524 for a 24 inch extension. For a 32 inch extension I recommend part...

  • Safety Chains And Trailer Wiring Extension For 48" Reese Titan Hitch Extender
    I recommend using the 48" Long Safety Chain with 1/4" S-Hook # TCTSCG30-748-04x2 with the Reese Titan Hitch Box Extension # RP45018. This chain includes s-hooks with built in latches on both ends of the chains that will allow you to easily remove the chains when they are not needed. You will need 2 of these chains for the extension. The TorkLift Wiring Harness Extension # TLW6048 will move your 7-way connection closer to the receiver and mount on the mounting bracket.
