Expert Answers about Jeep JL Wrangler


  • Can I Use the Exposed Racks ER74FR If I Have a Hard Top
  • Yes. You could use the Roof Rack for Jeep JL Soft Top - Square Bars - Steel - Black # ER74FR with the hardtop off; it's actually designed to be used with the top off so it sounds like it's the perfect solution for your 2018 Wrangler JL. You will need to remove the bars to put the hardtop back on, but if you ever decide to get a soft top then you can put it on over these bars. It's really a pretty cool solution! This rack will connect to the windshield housing and the speaker roll bar area.

  • How to Measure Loaded Trailer Tongue Weight
  • There is no way to use the Weigh Safe 2-Ball Mount with Scale along with a weight distribution (WD) system but you can use WD and measure your trailer tongue weight (TW) easily enough using the stand-alone etrailer Scale # e99044. The Sherline scale is compact and easy to use, and it reads up to 2000-lbs of loaded trailer TW.

  • Can The Roadmaster Invisibrake Be Installed In The Rear Compartment Of A 2018 Jeep JL Wrangler
  • I spoke with Brad, one of our installers here that's done quite a few Invisbrake installs, and he stated that box under the front driver seat is tucked in further than you'd think so you'd have to purposefully kick it and it wouldn't be an accident. That being said, it is possible to mount the compressor box in the back of your Wrangler but you'll most likely need to get some additional 1/4" nylon vacuum line to go from the box to the brake booster in the engine compartment and also some...

  • Recommended Curt Trailer Hitch for 2018 Jeep JL Wrangler Sport
  • You can install the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118786 on your 2018 Jeep JL Wrangler Sport so long as the flat tow wiring kit you used does not connect behind the tail lights, which you will need in order to install Harness # 118786. The diodes themselves will not be an issue as they are essentially just a gateway. A trailer hitch is also compatible with a flat tow set up and since you mentioned a Curt hitch I strongly recommend the Curt Trailer Hitch...

  • Does Computer Have to be Flashed on 2018 Jeep Wrangler w/ Tow Package to Use Curt Echo
  • The computer will not have to be flashed on your 2018 Jeep Wrangler in order to use the Curt Echo Wireless Trailer Brake Controller # C51180. Since your Jeep already has the 7-way and is ready to go, you'll just need to plug in the Echo, set it up with the app and you're set! I have added a link below to a video review for you to check out as well if you'd like to take a look.

  • Trailer Wiring For 2018 Jeep JL Wrangler
  • The Roadmaster Universal HyPower diode wiring kit part # RM-154 is different wiring than what you need for towing a trailer with the 2018 Jeep Wrangler JL. You will need a 4-pole flat wiring harness part # 118786 which will plug in behind the Jeep's tail lights. You will plug the trailer connector on the trailer into the 4-pole to power the lights. I have attached an installation video for your reference.

  • Will the Roadmaster EZ5 Base Plate Kit Fit a 2018 Jeep JL Wrangler Sport S
  • Yes, the Roadmaster EZ5 Base Plate Kit part # RM-521453-5 will fit your 2018 Jeep JL Wrangler Sport S as long as you have the factory front bumper. This base plate kits work with all motorhome mounted Roadmaster tow bars. For this, I recommend the Roadmaster Falcon 2 Tow Bar part # RM-520. In order to complete your flat-towing setup you will also need safety cables, supplemental braking system, tow bar wiring, and a possible high-low adapter. If you would like for me to recommend any of...

  • How to Carry an Electric Bike on a 2018 Jeep JL Wrangler
  • As long as the rear spare tire on your 2018 Jeep JL Wrangler is no larger than 15" wide then the Hollywood Racks SR1 2-Bike Carrier part # HRSR1 will fit. However, the max per bike weight capacity is 35 lbs so you cannot use this to carry your 50 lb electric bike even without another bike attached. The only way to carry a 50 lb electric bike on the back of your Jeep would be with a trailer hitch and hitch mounted bike rack. If you do not already have a trailer hitch I recommend the etrailer.com...

  • 2018 Jeep JL Wrangler Complete Flat Tow Set-Up
  • Yes, # RM-676 and # RM-521453-5 are compatible with your 2018 Jeep JL Wrangler. Both the Roadmaster Universal Hy-Power Diode Wiring Kit # RM-152 & # RM-154 are compatible with your vehicle. However, if you already have a 4-way at the rear of your vehicle, you can use # RM-154 to plug in the premade 4-blade to run to the front of your vehicle, or if you do not have a 4-blade at the rear, you can use # RM-152 to add one. The braking system, the Demco SBS Stay-IN-Play DUO Supplemental...

  • Best Trailer Hitch Receiver for a 2018 Jeep JL Wrangler
  • I do have options for you but the Curt Trailer Hitch Receiver part # 13432 is not a confirmed fit for a 2018 Jeep JL Wrangler. Instead, you will want to take a look at either the Curt Trailer Hitch Receiver part # C13392 or the Draw-Tite Max-Frame Trailer Hitch Receiver part # DT78MR. The above two options are both direct bolt-on fits that have a Class III rating with a 2" receiver tube opening. I recommend using the Draw-Tite Max-Frame as it is currently the more cost-effective option....

  • Will Hollywood Racks Sport Rider Bike Rack Clear Spare Tire on 2018 Jeep Wrangler JL
  • The Hollywood Racks Sport Rider SE2 2-Bike Rack # HR1450Z is 7-1/2 inches to the closest part of the rack so it will not clear your 2018 Jeep Wrangler JL's spare tire. In order to get this rack to clear the spare you will need to use an adapter, the Curt Hitch Extender for 2" Trailer Hitches - 14" Long # C45795. To secure the extender into your Jeep's hitch you will need either the Pin and Clip # PC3 or Anti-Rattle Trailer Hitch Receiver Lock # 63232. I have added a link to a video review...

The Guardian is going to do a superb job of keeping your Wrangler from any unnecessary damage when you're towing.

  • Recommended Flat Towing Equipment For A 2018 Jeep Wrangler JL
  • The Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar w/ LED Lights # RM-676 is a great choice for flat towing your 2018 Jeep JL Wrangler. It has a non-binding design which makes disconnecting a breeze on any terrain and a large hookup radius to make connecting to your base plates easy on any terrain as well. It has LED lights to help you hook up or disconnect in the dark and comes with a 6-way to 7-way cable and safety cables so you won't have to purchase them separately. To flat...

  • Can I Carry E-Bikes On My 2018 Jeep Wrangler JL
  • It will depend on which 2018 Jeep Wranger JL you are referring to. If it is the 4-door version, you may be able to use the the Hollywood Racks Sport Rider SE Bike Rack for 2 Electric Bikes - 2" Hitches - Frame Mount, part # HLY84FR. You will need to add a hitch extender. The spare tire on your 2018 Jeep Wrangler JL interferes with the installation of this hitch bike rack, unless you have an extender. I recommend the Curt Hitch Extender for 2" Hitch Receivers - 8" Long. part # C45791....

  • 6-Pin Socket That Works with the 6-Pin Bracket on a Blue Ox Base Plate Kit # BX1139
  • I tried looking up what 6-pin connector you have to try and see why it was not working with the Blue Ox Base Plate Kit # BX1139, but was not able to locate anything. Any 6-pin socket like what is included in the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 (included photo) should be able to work with that base plate kit. If you are unsure, you can send in a picture along with what 6-way you are using and I would be happy to take a look.
