To flat tow your 2018 Jeep JK Wrangler Unlimited you will need a base plate kit, tow bar, tow bar wiring, safety cables, and a supplemental braking system. I recommend the following:
-Roadmaster Direct-Connect Base Plate Kit # RM-521448-5 (For standard factory bumper)
-Roadmaster Falcon 2 Tow Bar # RM-520
-RoadMaster 68" Single Hook, Coiled Safety Cables # RM-643
-Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267
-Demco Stay-IN-Play Duo Flat Tow Brake System # SM99251

Hey John, so there's not a huge difference between the two trailer wiring kits you mentioned that fit your 2018 Jeep Wrangler Unlimited but since we have the best luck with Tekonsha kits I would go with the part # 118416 over the Curt # C55124. view full answer...
For your 2018 Jeep Wrangler JK Unlimited Sport we have the Roadmaster Exact Center Steering Stabilizer # RM84RR for stock tires up to 32" diameter. For Larger 33"-37" tires you would want the Stabilizer # RM39RR. This will will prevent the dreaded death wobble as there is not a wiring harness option I am aware of. view full answer...
