  • Compatibility of Hollywood Racks Spare Tire Bike Carrier on 2018 Jeep Wrangler Sahara Back-up Camera
  • The Hollywood Racks SR1 2-Bike Carrier - Spare Tire Mount # HRSR1 will fit your 2018 Jeep Wrangler Sahara spare tire. The backup camera will not be an issue with the rack fit as the straps are adjustable, however the view with bikes mounted will obviously be impacted. I reached out to my contact at Hollywood Racks to confirm it is compatible with both the backup camera and the tail light mounted behind and above the spare. You can see the tail light fit in the attached video at the 2:09...

  • Will 4-Flat and Tow Bar Wiring Both Work on 2018 Jeep JL Wrangler Unlimited
  • The Curt T-Connector Vehicle Wiring Harness # C56407 and Tow Ready 118821 will absolutely work together on your 2018 Jeep Wrangler JL Unlimited to give you a 4-way at the rear of your Jeep to tow your trailer and at the front to flat tow. The reason for this is the Curt connector will plug into the tail light housing while the Tow Ready will splice in; I recommend starting with the Curt and then installing the Tow Ready. The other option if you wanted to make things really simple is to...

  • Can Brake Light Relay RM-88400 Be Installed on a 2018 Jeep JL Wrangler Unlimited
  • The problem with the 2018 Jeep JL Wranglers is that the circuit you need to install the brake light relay # RM-88400 is inaccessible but it isn't required on this vehicle. When your JL Wrangler is set up in flat tow mode (see owner's manual) the brake light circuit is not active. That is why we do not list it for that particular vehicle. When in flat tow mode it will work fine. Or you can avoid all together by going with magnetic light kit # RM-2120. If your braking system has a monitor...

  • Yakima FullSwing 4 Bike Rack Compatibility with 2018 Jeep Wrangler Unlimited Sahara
  • The Yakima SwingDaddy 4 Bike Rack has a distance from center of hitch pin hole to top of upright bar of 9 inches. If you don't already have this hitch, then you may want to consider the Yakima FullSwing 4 Bike Rack # Y02465 which has that same 9 inches from the hitch pin. Depending on the hitch length and the tire width, you may or may not need a hitch extender like the Curt # C45791. Using a hitch extender will reduce the hitch's tongue weight capacity by 50% which shouldn't be an issue...

  • Difference Between The Roadmaster Crossbar And Direct-Connect Base Plates For A 2018 Jeep JL
  • The only difference between the Roadmaster Crossbar-Style Base Plate Kit # RM-521453-4 and Roadmaster Direct-Connect Base Plate Kit # RM-521453-5 is the style of the arms. The crossbar style was the original, but Roadmaster has strengthened their products and moved on to the direct-connect style which does not require the use of an additional crossbar. They actually just stopped offering the crossbars with their tow bars last fall as well, since they're no longer needed. With the direct-connect...

  • The Thule Hitching Post Pro- 1-1/4" and 2" Hitches # TH934XTR has a measurement from the center of the hitch pin hole to upright bar of the carrier of 13-1/2 inches.

  • Square Crossbars for Thule Gutter Feet on a 2018 Jeep JL Wrangler Unlimited
  • We do have a solution for you to have a square bar roof rack on your 2018 Jeep JL Wrangler Unlimited but unfortunately you won't be able to use Inno bars as they are not compatible with the Thule feet. I am not sure what the 150 Thule feet are that you referenced but I can say that the correct gutter feet for your 2018 JL is part # TH65BJ for the newer 60" SquareBar Crossbars # TH712500. If you would like to add locks to your roof rack then you also need the 4 pack of lock cores # TH450400. Attached...
