What Do I Need to Flat Tow My 2018 Jeep JL Wrangler?Every flat-towed vehicle requires the same 5 components: base plates, a tow bar, safety cables, wiring, and a braking system.That said, there's plenty of variety in these products, plus additional parts that may be required for certain vehicles. Your Jeep JL Wrangler, for instance, requires a stop light switch. You can also purchase optional covers, screens, and guards to protect your vehicle and flat towing components from wear and tear. Flat tow products are available for both standard Jeep Wrangler JL models (factory plastic bumper without winches or guards) and models with the steel bumper package. We've hand-picked the best products confirmed to fit these models. The standard packages are listed first; scroll down to see packages for the steel bumper models.

Recommended Parts Needed to Flat Tow a Jeep Wrangler JL or JL UnlimitedFor your Jeep Wrangler JL, I recommend starting with the RoadMaster EZ5 Base Plate Kit # RM-521450-5. This kit has removable arms to give you a very clean look when not flat towing your Jeep, and also gives you a clean connection to your tow bar when towing behind your motorhome. I recommend installing this base plate using Loctite threadlocker # LT37420 to keep your hardware from vibrating loose over time. For your tow bar, I recommend the RoadMaster Nighthawk All Terrain, Non-Binding Tow Bar w/ LED Lights # RM-676. This tow bar comes with the integrated safety cables and the wiring to link your motorhome's 7-way trailer connector to a 6-way connector on the front of your Jeep...View full answer...

Tow Bars for 2018 JL Wrangler

Another necessary component of a flat towing setup is the tow bar. While tow bars are not a custom-fit component, it is important to make sure that the tow bar and base plates you choose for your JL Wrangler or JL Wrangler Unlimited are compatible with each other. A good rule of thumb is to use a tow bar from the same manufacturer as your base plate kit. If you have base plates or a tow bar of one brand and wish to use a counterpart from a different manufacturer, you will likely need an adapter. Check out our base plate adapter table for help on choosing the correct product.Tow bars come in two styles: those that mount on the motorhome (hitch mount style) and those that mount on the vehicle (coupler style). For frequent RVers, motorhome-mounted tow bars are generally preferable. They provide a more stable connection, are easy to adjust, and do not require a separate coupler. On the other hand, those who RV less frequently may consider a vehicle-mounted tow bar for a more economical option.

Safety Cables for 2018 JL Wrangler

Safety cables are a necessary component of a flat towing setup. Keep the weight of your Jeep JL Wrangler or JL Wrangler Unlimited in mind when choosing safety cables, as safety cables come in a variety of capacities. Blue Ox and Demco typically include safety cables with their tow bars, making it easy to complete your flat towing setup. Both manufacturers also offer replacement safety cables. Some premium Roadmaster tow bars include safety cables, but most do not. Roadmaster offers a number of capacites and both coiled and straight cables for your flat towing setup. The coiled design helps keep the safety cables from dragging the ground, while straight cables work best with tow bars that have channels, or cable guides, for the safety cables to feed through.

Tow Bar Wiring Kits for 2018 JL Wrangler

It is important for your JL Wrangler or JL Wrangler Unlimited to be wired for flat towing. Tow bar wiring allows your vehicle to have functioning stop, turn, and tail lights while being towed. To make sure your Jeep has functioning tail lights when towed, the Jeep can be hardwired to use the existing tail lights, or a universal lighting kit can be used to add additional lights to your Jeep specifically for towing.

Supplemental Braking System for JL Wrangler

Using a supplemental braking system, also called a tow bar braking system, helps make sure your towed Jeep slows down as your motorhome slows down. This helps reduce wear and tear on both your Jeep and your motorhome, as well as helps shorten the braking distance of your towing setup. It is also important to keep in mind that supplemental braking systems are required by law in many states. It is important to check the requirements for areas you will be traveling through.

Additional Flat Towing Components

To complete your Jeep Wrangler or Wrangler Unlimited's flat towing setup, a few additional parts may be required or recommended. Some of these components, such as 12-volt accessory outlets, stop light switches, and high-low adapters, ensure that your flat tow setup functions properly. Other accessories work to protect your JL Wrangler or JL Wrangler Unlimited from rocks and other road debris while your vehicle is being towed.Required AccessoriesIn addition to your main wiring harness, you'll also need a few additional components to make your setup fully functional. A stop light switch activates your RV monitoring system to alert you when the brakes of your towed car are being applied. A charge line kit maintains the battery charge in your towed vehicle (though it is not required when using the Roadmaster Invisibrake, which provides its own charge). A 12-volt outlet kit provides power to portable braking systems but is not required for fixed systems.

However, if your tow bar is not level, you will need a high-low adapter. Your tow bar should always be within 3 inches of level. A tow bar cover is also recommended to protect your tow bar when not in use.
