  • modern receiver hitch and M37

    I have a '52 M37. Now that I have finally finished my civvie PW resto, I am going to start on the M37 this winter.
    My M37 is going to look stock on the outside but have some upgrades in the power train, seats and brakes.
    Last month I removed a stock class 3 receiver hitch from my 2001 Ram and replaced it with a class 5. I thought this old hitch would be just extra iron laying around unless I could sell it locally.
    Last week I was doing a little measuring and inspecting, and just for curiosity sake took the receiver hitch over and held it up to the frame rails of the M37. It looks like it will drop right in with just a very small amount of grinding of the edge of its ears in a few places! The receiver opening will be below the pintle, so I can keep that. How often does that happen- with this many years and design differences? Maybe Murphy is not always on duty!

    Wow great! Any pics of the install? Does the stock hitch have the tabs face outward or inward? I mean does the hitch mount in-between the frame rails or on the outside?

      Hi Jared,
      I will try to get some pics soon...I got the frame and axles done but then the project has been on hold and I haven't finished the hitch.

        Doc Dave - I'm wondering what ever came of this project. I'm just getting started on my M37, and trying to figure out how I might add a receiver hitch.

          After my original post in 2011, I had a lot of "life happens" situations going on. I only recently went back to the M37.

          Among other things I got the gas tank Renu'd and installed, and fabricated the fuel and return line fittings to this.

          I'm happy to say the stock Dodge 3/4 ton pickup receiver hitch from my 2001 Ram fit the M37 perfectly!
          i was able to use the existing holes in the hitch flange as a guide to drill 1/2" holes in the lower frame ears. I used grade 8 bolts to attach the frame and the results are very nice.
          i did not have to grind or modify anything.

          I blasted the hitch in my media blaster cabinet and then painted it black.

            Doc Dave - Sounds interesting. Any chance you can post some pictures?

            I'm wondering if the frame will need to be reinforced in that area on my truck. It's sitting on 11.00x16 tires, so I'm guessing I'll still need a significant drop on my receiver insert to get the ball to an appropriate height. That could put lot of twisting force on the frame, particularly when I'm operating on rough terrain.
