The Timbren Active Off-Road Bumpstops # TABSJRJK referenced in your question are confirmed to fit your 2018 Jeep JL Wrangler Unlimited. These are designed to replace the factory bump stops on your Jeep and will provide a stronger unit that will do a better job of supporting the rear suspension and absorbing energy and cushioning road shock. These should definitely help a bit with the rear sag on your Jeep when hooking up to a trailer, but it's not your best option.
When rear sag on a vehicle is the result of a trailer's tongue weight (and not from cargo loaded into the vehicle itself) the best and most effective solution is a weight distribution system. A weight distribution system will evenly distribute weight over the axles of the trailer and tow vehicle so that everything remains level.
I have attached a great FAQ on weight distribution systems that you can check out.
In order to pick out the correct system, you will want to determine your total tongue weight. This number includes both the loaded tongue weight of your trailer (as if loaded and ready for a trip), along with any additional cargo weight coming from behind the rear axle of your Jeep. Ideally, this number will fall somewhere near the middle of the operating range for the system you choose. Using a tongue weight scale like the etrailer # e99044 is the most accurate method for determining your trailer's loaded tongue weight.
If you can tell me the loaded tongue weight of your trailer, I will be happy to recommend a great weight distribution system for your setup.
