I needed a heavy duty 2" hitch for a few reasons. 1st I have ALS and will be using a heavy power wheelchair in the near future. So I need to mount it on a lift on the back of my Cmax. Combined weight is about 350 lbs. 2nd I have a great 2" bike rack that doubles as a hitch hauler. My choices were a 350 lb 1.25" Curt and the 150 lb 2" Ecohitch. I probably won't carry more than 150 lbs on the rack so the Ecohitch (150 lb limit) would have been fine for that.
So I ordered the 350 lb limit Curt hitch from Amazon delivered for $120, and had a welder modify the hitch to 2". I brought him the hitch and a 6" long, 2" Drawtite receiver bar from Tractor Supply ($20). He cut off the 1.25 bar and welded on the 2" bar for $75. See pics. All modifications were under the bumper so I knew it would still fit on the car. We then sanded off the heat affected paint with a drill and a paint removal poly wheel and painted with Rustoleum gloss black paint.
Then I got 2 friends to come over and install the hitch which I'll cover in a separate thread.
I am very happy with the result. And the difference in capacity vs Ecohitch is obvious when you look at the picture of the bolts side by side. Ecohitch uses 6 of the small bolts threaded into Cmax frame rail inserts while the Curt uses 4 small bolts into inserts and 2 large bolts with a 1"x2"x.25" steel load spreader bar up inside the frame rail which is much stronger than an insert. The big bolts go through the 2 holes you drill. These big bolts are in almost pure tension so they're also in the right place to increase capacity.
Now the bad news. Nobody would install a modified hitch so if you go this route plan on installing yourself or get a welder who specializes in hitches and get him to do it all.
And finally i'd like to say I'm not criticizing the Ecohitch. For most people it's a very good and easy to install hitch. I just needed more capacity than most do.
Oh and btw that's an electric lawnmower on the back of my Energi.
