homemade bumper hitch stock bumper with pics

I decided that the $350 the local shops were wanting to charge for a hitch on a vehicle rated at only 2000lbs was too much. So I built my own. Cost $45. Used a single piece of angle iron 2x2x1/8, drilled holes in the bumper mount used 1/2" grade 5 bolts to mount it. Bought a Reese class II step bumper hitch for $35 and drilled holes in the bumper and angle iron. Mounted the hitch and my mechanical engineer friend rated it at 1500 lbs. I will be putting a second piece of angle iron on back to back with the existing one using the 3/8" bumper mounting bolts already there. This will bring the hitch's strength up to 3500lbs with a 550lb safety factor. Fast cheap easy. No welding only holes to be drilled. And careful measurements to ensure correct placement.

This scares me a bit. Did you tie into the frame on the outside as well? It looks like it's just bolted to the bumper

probably fine for a bike rack, but I hope you don't plan to actually tow anything with that.....

It is completely tow worthy. I pulled my trailer with it after installation, unloaded of course. But after I put the other piece of angle in using the bumper mounts on the bottom of the frame I will test it under a full load of 1500lbs or so. My friend who holds a masters in mechanical engineering says it is a sound design. That the hitch will hold, and support the 350lb Max tongue weight given by the Reese class II step bumper hitch. In fact with the 2nd piece of angle iron installed it will be stronger than the mounts on his 03 Tahoe which he installed the same hitch onto and regularly pulls a 2 ATV trailer with.

You know you can get a rugged ridge hitch and wiring for $65 off amazon, even has free Prime shipping.

That's what we are all wondering about yours. Pics are hard to say. It looks like it's bolted to your bumper, not to the frame, which most hitches bolt to the frame I'm atleast 4 locations

At the moment because my drill died, it is bolted to the bumper and the angle iron is bolted to the mount that goes under the bumper to the frame. No at the moment
it isn't bolted to the frame. But it will bolt to the frame with the 2 3/8" bolts that hold the lower bumper mount onto the frame. That will then bolt to the piece that is in place with 4 grade 5 bolts. Many small pickups use a ball mounted onto the bumper as a hitch rated at 2000lbs. And their bumpers aren't mounted on as strongly as the tj. And is really no more substantial in strength. Truly the strength of this design comes down to the sheer strength of the 1/2" grade 5 bolts which is around 3800lbs depending on whose chart your looking at.

Many jeep bumpers are ripped off the back after mounting tow hooks to the bumper, the welds are not strong enough.

Which is why the angle iron crossbeam it is also mounted to is bolted on the other side of the weld, I took that into consideration. And my safety chains will be attached to the frame mounted tow hooks. The only reason a bumper would be ripped off because of the tow hooks is because they used a sudden jolt of force to recover a stuck vehicle (either the jeep in question or another) and since the trailer I have when loaded with my ATV weighs half what a jeep does, and since the majority of the strain on a hitch occurs when motion begins or ends, as long as I'm not jerking my trailer around on stops and starts I really can't see it tearing anything.

Sounds good man, just giving some helpful tips. Your pics leave a lot to question and your faith in factory welds is suspect. Hopefully it is tied in well and you never have any issues

I do appreciate the criticism. It does only assert that I need to get my reinforcement piece in place before I tow my trailer loaded.
