Tork Lift Cannon Extender

This Cannon hitch extender is specially designed to work with your 3" factory Ford Super Duty trailer hitch. 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 Cannon, though, creates such a sturdy connection with your 3" OE 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 shank of the Cannon extension slides into your receiver and is held in place with the included hitch pin and clip. The connection between the extension and your hitch is reinforced with a set bolt underneath the shank that tightens up to the receiver for a snug fit and prevents rattle and movement in hitch.

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 hitch. 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 Cannon 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.

Ask the Experts about this TorkLift Hitch Adapters

  • Hitch Extender that Can Fit Ram 3500 that has 2-1/2 inch Hitch Extender
    We do have great hitch extender options for trucks like your that have 2-1/2 inch hitches like the Curt part # C45048 but the # TLE1642 only fits the new Ram trucks that have 3 inch hitches. The Curt # C45048 can be used as a 34 inch extension or cut down to a 24 inch extension which typically works great for camper applications like yours. Check out the review video I attached for more info on this as well.

  • 42 Inch Hitch Extension for 2020 Ford F-350 with In-Bed Camper
    We have the TorkLift Cannon Hitch Extension for 3" Ford Super Duty Factory Hitch # TLE1642. You will not be able to use an extension of this length with a rise hitch adapter. This is because the 42" hitch extender has to be secured with lateral-support safety chains in a straight line

  • Recommended Hitch Extender For 2018 Ram 3500 DRW With Max Tow Package
    Based on all of the information I was able to find on your 2018 Ram 3500 DRW with the max tow package your truck should have a 2-1/2" trailer hitch receiver. For a 2-1/2" receiver you will need the Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches - 24" to 34" Long # C45048 which can be used as a 34" extension of cut down to a 24" extension. This extender has a 450lb tongue weight and 4500lb trailer weight rating or 600lb tongue weight and 6000 trailer weight rating when using...

  • 42" Trailer Hitch Receiver Extension For 2020 Ram 3500
    The TorkLift Cannon Hitch Extension # TLE1642 is designed to work with trucks that have a 3" factory cross bar style trailer hitch receiver. To my knowledge I have only ever seen those on the 2017 and newer Ford F-350's. I believe that your 2020 Ram 3500 has a 2-1/2" receiver from the factory. If that is the case you will need to replace your hitch with the TorkLift SuperHitch Magnum Trailer Hitch Receiver # TLD1111-30. Then you will be able to use the TorkLift SuperTruss Hitch Extension...

  • Hitch Extender for 2-1/2" Hitch on 2020 GMC Sierra 3500 Dually
    I have a solution for you, but the TorkLift # TLE1642 is designed to fit in a 3" hitch receiver and reduces your hitch down to a 2-1/2" receiver. If you're looking for an extender that fits in a 2-1/2" receiver and will reduce it to a 2" receiver, the Curt # C45048 would be what you're looking for. It does not appear that we have anything available that will extend a 2-1/2" hitch and not reduce it, nor is there an extension that would make the receiver larger.

  • Can I Use the TorkLift Cannon with a Weight Distribution Hitch
    The weight distribution hitch you'll want to use will depend on the GVWR and tongue weight of your cargo trailer; you ideally have a WDH that the tongue weight of your trailer falls right in the middle of the range. Assuming that you tow the maximum that the Torklift Cannon # TLE1642 will allow (660-lbs TW/6600-lbs GVWR), something like the Curt Curt Trunnion Style Weight Distribution System with Shank, 800 TW, 8,000 GTW # 17301 would be a good choice. This system will fit in the Cannon...

  • Hitch Extender for 2017 Ford F-350 With 3 Inch Factory Hitch
    There is one extender that will work with the 3 inch factory hitch on your 2017 Ford F-350 Super Duty, the TorkLift Cannon Hitch Extension, and it comes in three different lengths: 36" Long # TLE1636, 42" Long # TLE1642 and 48" Long # TLE1648. The shorter 36 inch extension, which is likely what you can use since you mentioned the camper will only hang over 16 inches to 18 inches, has a towing capacity of 3,600 lbs and tongue weight capacity of 360 lbs, though that rating is increased...
