To add a hitch to your 2023 Jeep Wrangler 4xe, I recommend the etrailer Hitch item # e98856. This hitch is custom fit and attaches directly to your Jeep's bumper with four included bolts. This hitch is one of the easiest to install on the market.
This is a class III hitch with a 2" receiver. It has a 3,500 lbs towing capacity and a 350 lbs maximum tongue weight. I have linked an installation video below.
If you are planning on towing you will also need a wiring harness item # 118786... view full answer...
