TorkLift SuperTruss in SuperHitch

This SuperTruss hitch extender is specially designed to work with your SuperHitch trailer hitch (sold separately). Like most products from TorkLift, the primary purpose of this extender is to help create a towing setup that fits perfectly with your truck bed camper system. Not only will you be able to extend your trailer hitch receiver out far enough to clear the overhang of your camper, but you will also maintain a high enough weight capacity so that you can tow your trailer.


Heavy-Duty Towing with a Hitch Extension

Most hitch extensions dramatically reduce the towing capacity of your hitch setup, making it difficult to tow a loaded trailer over a certain weight. The SuperTruss, though, creates such a sturdy connection with your SuperHitch trailer hitch that you can still maintain a high weight capacity. To get the highest capacity possible, use a standard weight distribution system with the TorkLift towing setup.


The SuperTruss uses both of the receivers on your TorkLift SuperHitch to ensure a sturdy, secure connection. The solid shank of the extension's top tube slides into your top receiver, and the extension's lower compression tube installs in your bottom receiver. Each tube is held in place with the hitch pins and clips that were included with your SuperHitch. The connection between the extension and your hitch is reinforced with 2 sturdy steel collars that bolt around the tubes of the SuperTruss.


To give you absolute peace of mind, lateral support chains connect to the hitch and the extension on either side of your setup. Just attach one end of each chain to the extension and secure the opposite end to your SuperHitch. Then tighten the chains with the integrated turnbuckles. These chains not only provide extra security to keep the extension in place in your hitch, but they also transfer some of the weight back from the extension to your frame-mounted hitch.


How to Determine the SuperTruss Length You Need

If the camper is mounted on the truck:

Measure from the face of the truck's rear bumper to the outside edge of the camper's bumper. This is the length of the extension that you need.


If the camper is not mounted on the truck:

1. Measure from the inside of the front of your truck bed to the outside face of the truck's rear bumper.

2. Measure the camper's overall floor length from the rubber bumpers at the front to the outside edge of the rear bumper.

3. Find the difference between these 2 figures by subtracting. The difference is the length of the extension that you need.

Worked perfectly for what I needed it to do!

Perfect fit



by:

Excellent hitch and extension, really well built and easy to install. Needed this pull a 9000 lb trailer with a Polaris RZR in the back of my truck, and it allows me to do this with the tailgate down. So pleased with this product!



by:

Have not towed a trailer with it yet but have it installed and looks like it will get the job done. E trailer is easy to do busy with plus fast shipping.



by:

I bought the super hitch too. E-Trailer is awesome! Everything got to my house quick and was east to install. I will be using E-Trailer for all my future needs.



by:

As with the other review, I did not install this device as it turned out my truck was not designed for the stresses it would put on the frame. To 'beef it up costs' would have been prohibitive.
The item is still in storage in my garage.
So I can't write a review for a product I did not use.



by:

Product arrived on time and in good condition. Have not pulled with it yet but maybe complete setup this afternoon. Heavy duty well built truss extension. Thanks

  • Solution for Hitch Extension With 1,000 Pound TW and 10,000 Pound GTW Capacity on 2000 F-350
    I have a possible solution, but none of the 14-16" extensions have a high enough capacity. The only thing that comes close is the Gen-Y # GY89SR which has a gross towing weight of 10,000 lbs, but the max tongue weight is only 500 lbs. This would also reduce the capacity of your hitch by 50% like many hitch extenders do. If you can handle it being slightly shorter, what you could use instead is the Brophy Ball Mount for 2" Hitch # BH20. This is 13-1/4" long and has the capacity you need....

  • Options For Pulling a Boat Trailer Behind a 2014 Dodge Ram 3500 with an In-Bed Truck Camper
    The longest extension available that will work with the factory trailer hitch receiver on your 2014 Dodge Ram 3500 is the Trailer Hitch Extender # e48YR. You will need to measure from the center of the hitch pin hole on your trailer hitch receiver to the edge of your truck bed camper to see if this extension is long enough. Keep in mind that a hitch extender like the # e48YR will reduce your trailer hitch receivers capacities by 50%, and has a max tongue weight rating of 350lbs and a max...

    There are two different TorkLift SuperHitch Magnum Trailer Hitch Receiver's for your 2008 Ford F-250. There is part # TLF1002-30 which has a 2-1/2" an 2" receiver tube opening and part # TLF1002 which has two 2" receiver tube openings. The receiver tube opening size is the only difference between the above two hitches. I was not able to reference the different frame widths you mentioned. If you also need the TorkLift SuperTruss and then you can use one of the following depending on the...

  • Recommended TorkLift SuperHitch for a 2016 Dodge Ram 2500 with Factory Hitch
    Good news! The two TorkLift Super Hitch confirmed fit options for your 2016 Dodge Ram 2500 Laramie with factory hitch are the 2 inch # TLD1109 or 2-1/2 inch # TLD1109-30. Since you plan on using the # TLE1521 or # TLE1524 you will most likely want the TorkLift 2 inch version # TLD1107. I have linked all the above mentioned products to this page for your convenience.

  • Hitch Extender for a 2007 Chevy Silverado 2500HD Short Bed Towing a Horse Trailer
    When you use a hitch extension in a 2 inch or 1-1/4 inch receiver it will reduce the tongue weight capacity of the hitch by 50 percent. But if you have a 2-1/2 inch receiver the tongue weight capacity is not reduced but usually the capacity of he extension is lower than the hitch so you would go by the lower rating. If you have a 2-1/2 inch receiver opening you can use the Titan extender # RP45292 at the 24 inch length. That will give you a capacity of 6,000 pounds; 8,000 when using weight...

  • Why is Tongue Weight of Roadmaster Hitch Extender # RM-071 100 lbs
    The Roadmaster Hitch Extender part # RM-071 that you referenced is designed to be used only in flat towing situations where there wouldn't be hardly any tongue weight. This is due to the fact that the vehicle being towed has all 4 wheels on the ground unlike a trailer that only has one axle. It's not rated for trailer use, but it can be used when flat towing a vehicle up to 6,000 lbs. Even our most heavy duty hitch extenders like the Torklift Super Truss part # TLE1521 have lower capacities...

  • Recommended Heavy Duty Trailer Hitch Extension For 2020 Ford F-350
    I do have an option for you, but you are correct that you will need to replace your trailer hitch receiver. For the new trailer hitch receiver you will need the TorkLift SuperHitch Magnum Trailer Hitch Receiver # TLF1008-30 which has a 20000lb max trailer rating and 2500lb max tongue weight rating, but those numbers get bumped to 30000lbs max trailer rating and 3000lb max tongue weight rating when using weight distribution. Now the reason you need the new hitch is to be able to use the...

  • Is there a 12 Inch Long Hitch Extender Rated for Towing a 10,000 lbs Trailer with a 2014 Ram 3500
    The hitch extenders that are rated for 10,000 pounds are all for tow bar applications only so we have to take a different approach. If you have the factory trailer hitch that is welded onto your 2014 Ram 3500 then the best option would be to add TorkLift SuperHitch # TLD1108 and then use SuperTruss Extender # TLE1521. When using the SuperTruss extender you would have to then use weight distribution to get the capacity to 14,000 pounds.

  • Hitch Extension for Use With Truck Camper
    By extension that "uses chains to the corners of my truck hitch" I assume you are talking about an extender such as the TorkLift SuperTruss Hitch Extension # TLE1521 which attaches like in the accompanying photo. The SuperTruss extenders that use chains are only fits for TorkLift SuperHitch dual-receiver trailer hitches so these would only fit if you had one of those on your truck. As for 18" hitch extenders such as the Curt # C45796, there are none we carry which use chains that attach...

  • How to Carry Two Bikes on a Truck with a Truck Bed Camper
    I do have an option for you but you cannot use two adapters together. The use of even one adapter would decrease the vehicle/hitches tongue weight capacity by 50%. This means that the weight of the two bikes plus weight of the carrier would need to be below 50% of either the vehicle or trailer hitches tongue weight capacity. If the vehicle's tongue weight capacity is lower than the hitches tongue weight capacity than this is the figure you will need to go by or vice versa. Instead, you...

  • Torklift SuperHitch that Fits 2003 Chevy Silverado with 21 inch Hitch Extender
    The Torklift SuperHitch part # TLC1204 is the correct fit for your 2003 Chevy Silverado 2500HD short bed. And then the correct 21 inch Torklift hitch extender is the part # TLE1521 and you'd be set! As long as you are under the weight capacities of the truck and towing components you'd have no negative affects while towing.

  • Hitch Extender for 2014 Toyota Tundra Towing Trailer with Weight Distribution
    The further you extend the connection point between the truck and trailer and the more adapters you use, the less your weight capacity will be. The Brophy Hitch Extender part # ST18 can be used with a weight distribution system but you will reduce your towing capacity by 1/3 or 7,000 lbs, whichever is lower. Therefore, if the trailer hitch on your tow vehicle is rated for 13,500 lbs or more then you can use the Brophy Hitch Extender. There are other adapters available but each manufacturer...

  • Can I Extend My Hitch Without Using TorkLift Hitch and SuperTruss Extension
    The only other extension option we carry besides the Torklift SuperTruss extender that does not cut your tongue weight in half is an extra long ball mount. Traditional extensions such as part # C45796 cut the tongue weight capacity of the hitch on the truck in half because it creates extra leverage and movement in your towing setup. The only extra long ball mount we offer that is long enough for your setup is the Hidden Hitch ball mount part # BM20 at 13-1/4 inches long. That length is...

The Equal-I-Zer weight distribution head will also fit Reese shank # RP54976 which is 15 inches long but there are no 2-1/2 inch options that are 18 inches long. What you could do is install the Tork Lift Super Hitch Magnum, # TLF1008-30, on your 2017 Ford F-250 and then use the SuperTruss extension, # TLE1521.

    The correct Torklift hitch for your 2012 Ram 2500 that has a bolted on factory trailer hitch is the part # TLD1101. We have confirmed this fit with Torklift so we know it will work. For Supertruss extensions we have three options. The part # TLE1536 for 36 inches, part # TLE1521 for 21 inches, and part # TLE1524 for 24 inches.

    The Curt Trailer Hitch Receiver - Custom Fit - Class V Commercial Duty - 2-1/2" # C15809 is a great option for your 2011 Ram 2500 as long as you are okay with a 24 inch hitch extension like # C45048. This will give you a gross trailer weight of 8,000 lbs when used with weight distribution, so a weight distribution system would be required. Your other option is to use the TorkLift SuperHitch Original Trailer Hitch Receiver - Custom Fit - Class V - Dual 2" Receivers # TLD1102 instead...

  • Towing a Boat Trailer with Folding Tongue Using Weight Distribution with Camper in Truck Bed
    It is not a good idea to use weight distribution with a folding tongue due to the amount of force applied by the spring bars to the trailer. If you were to do it you would need to have a pole tongue adapter such as # RP58393 since the trailer does not have a traditional A-Frame. The other issue is that you would need a system rated much higher. This is because when you calculate tongue weight for weight distribution you have to add in the weight of anything loaded behind the rear axle...

  • Bolt Holes Not Lining Up for Torklift SuperTruss Hitch Extension
    We are not familiar with the problem you're describing on the TorkLift SuperTruss Hitch Extensions, # TLE1521. TorkLift makes their products here in the USA, but it is possible that your extension was made on a Monday. I spoke with my contact at TorkLift about the issue you have experienced with your extension. She confirmed that when installing the extension, the bottom bolts should be tightened first, then the top bolts. If the top bolts are tightened first, this can cause the holes...

The Reese System # RP66075 is rated for trailers with a tongue weight of 1,000-1,700lbs and a maximum trailer weight of up to 17,000lbs.
