You may just have to wait till you pick up the trailer. You will want it pretty level when attached or maybe a bit higher in the front depending how heavy you load the front of the trailer. Do make sure you have some weight up front, will keep trailer more stable. You will also need receiver...
That's interesting that they would lift 2.5 inches in the front and no rear. You can add spacers to the rear to level things out. Just figure how much height you need and put in that amount. you can buy spacers for the rear in a variety of sizes.
I have 5 Rubicon wheels in very good to excellent shape. No TPMS. They are off of my 2019 Jeep Wrangler Rubicon 2dr and were driven approximately 2000 miles. I live in southeastern Washington and am not able to ship. If someone wasn't too far may be willing to meet for gas money. $500 set.
Tereflex rear track bar correction bracket. I like it solid easy install, you can see how parallel it makes the track bar to the axle. Went on a cruise over a really poor condition asphalt road and at 50 to 60 mph this Mojave is awesome. Not sure how much the bracket helped though...
