Question:

I have a 2018 GMC 3500 Dually with a 2.5” receiver. I haul a Arctic Fox 990 camper and need a 36” hitch extension as I want to pull my 2015 2 door Jeep Wrangler behind. Can I use a Super Truss extension with my stock hitch OR do I require the Super Hitch receiver?

Expert Reply:

You will need to use the TorkLift trailer hitch on your 2018 GMC Sierra 3500 in order to use the SuperTruss 36" Extension # TLE1536. The reason for that is the extension is designed to fit the dual receivers of the SuperHitch as opposed to the single receiver of the OEM hitch on your Sierra.

You can also choose from a SuperHitch with dual 2" receivers or with a 2-1/2" and 2" receiver, with the extension fitting either. I'll list out the options, as there are different fits depending on if your '18 Sierra 3500 is a long bed or short bed:

Long Bed
- Dual 2" Receivers: TorkLift SuperHitch Original Trailer Hitch Receiver # TLC1211

- 2-1/2" & 2" Receivers: TorkLift SuperHitch Magnum Trailer Hitch Receiver # TLC1211-30

Short Bed:
- Dual 2" Receivers: TorkLift SuperHitch Original Trailer Hitch Receiver # TLC1212

- 2-1/2" & 2" Receivers: TorkLift SuperHitch Magnum Trailer Hitch Receiver # TLC1212-30

Then for the 36" extension, the correct part is the TorkLift SuperTruss Hitch Extension for SuperHitch Trailer Hitch Receivers # TLE1536.

You can secure it with Pin and Clip # C21510 or Hitch Receiver Lock # e98881; for a wiring extension you will need the TorkLift Wiring Harness Extension for 36" SuperTruss # TLW6036.
