Expert Answers about Jeep JL Wrangler


  • Recommended Suspension Enhancement to Reduce Sag on 2018 Jeep Wrangler JL
  • For the rear sag on your 2018 Jeep Wrangler JL, I recommend the Timbren Active Off-Road Bumpstops - Rear Suspension - 2,400 lbs # TABSJRJK does not allow for spacers so it won't reduce your sag much. My recommendation that will allow adjustment to fill the space and reduce sag is the Air Lift AirLift 1000 Air Helper Springs for Coil Springs - Rear # AL60829. If you want the compressor for adjustability at anytime you can use # AL25980.

  • Why is the Roadmaster Stop Light Switch Kit Needed for a 2018 Jeep JL Wrangler
  • I cannot tell you the exact "influencer" as you referred to it as but while the vehicle is setup for flat-towing, the brake light switch will shut off after 10 minutes of inactivity. If you open or close the door that will then wake the vehicle up but as you will not be opening and closing the door while in tow you will need to use the Roadmaster Stop Light Switch Kit part # RM-751490 in order for a supplemental braking system to function properly on your 2018 Jeep JL Wrangler. If you...

  • Can Demco Commander Tow Bar be Used with Tabless Base Plate Kit
  • Demco has confirmed that their Commander Tow Bar part # DM9511012 does work with the Tabless base plate kits like the part # DM9519339 that fits your 2018 Jeep Wrangler JL. Sometimes tow bar heights and base plate heights don't line up perfectly. That is why companies like Roadmaster created high low adapters like the # RM-048-6 which can give a 6 inch rise or drop.

  • Wiring Harness Compatible with 2018 Jeep Wrangler JL Unlimited Sahara
  • The T-One Vehicle Wiring Harness #118782 is not a fit for the Sahara or Rubicon models and has been discontinued. Instead you will want the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118786. This harness is the updated replacement for the previous harness that is compatible with your 2018 Jeep Wrangler JL Unlimited Sahara. This harness will install behind the driver's-side and passenger side tail lights. Once you've plugged in the harness, you will run the hot...

  • How to Protect a Toad from Chips or Scratches While in Tow
  • The Snoblock Snow and Ice Windshield and Wiper Blade Cover part # 288-06603 is not designed to be used on a moving vehicle. If used in this fashion then the chances of it tearing would be increased therefore I cannot recommend this. However, we do still have multiple ways of protecting your toad while in tow and not just the windshield portion either. For this, I recommend taking a look at Sentry Deflector part # DM9523135 if you have a Demco Tow Bar, the Guardian Rock Guard part # RM-4000...

  • Haul 2 Kayaks on Pioneer Platform Roof Rack
  • I do have a solution for you to mount two kayaks, however a Hullavator must be mounted on a crossbar that extends 4 - 8 inches beyond the crossbar foot at the roof's edge. It will not mount to the Pioneer Platform. Even if you decided to mount crossbars over the platform sticking out 4" to 8" on each side, they would still not clear those ladders on the side of your vehicle. It appears that your roof is less than 60" wide so tying down two 30" wide kayaks side-by-side on the Pioneer...

  • Kayak Load Assist for Jeep Wrangler Roof
  • I have a few solutions for you. The first one is using your current roof rack and kayak carrier setup while using a step assist like Powerbuilt Adjustable Tire Step # ALL647596. This gives you a large step that attaches to your tire to help with loading and unloading of your kayaks. The Rightline Gear Moki Door Step # RL100660 is another option. It hooks into your door's latch and provides a step to give you better access to your roof. This style is nice because it allows you to reach...

  • Swing Away Platform 2-Bike Rack Solution
  • For a two bike rack similar to two Yakima HighRoad bike racks part # Y75FR that you can use with the Yakima EXO Swingbase part # Y34VR you'd want the Yakima EXO Double Up part # Y24VR. The channels of the Swingbase are not compatible with standard bike racks and require racks specifically made for them. Or for a similar pivoting platform bike rack we have the RockyMounts BackStage part # RKY10002 which is a little easier on price.

  • Installing Trailer Wiring Harness on 2018 Jeep JL Wrangler Thats Also Wired for Flat Towing

The two kits won't interfere with each other and won't cause any type of issue with regards to the electrical system on the Jeep.

  • Does Roadmaster Sterling Tow Bar Come with Crossbar
  • Sounds like you are looking for the crossbar that is used on the Roadmaster flat towing setups. The good news is that if you ordered a Roadmaster Sterling Tow Bar part # RM-576 it comes with this already. For the missing arms of your base plate kit you'd need just the part # RM-ARMS.

  • Base Plate and Parts to Flat Tow 2019 Jeep Wrangler with Steel Bumper
  • We have base plate kits that fit your 2019 Jeep Wrangler Rubicon with the factory steel bumper like with the Roadmaster Direct Connect part # RM-521453-5 but at this time there are no Blue Ox options. In addition to the base plates, you will also need a compatible tow bar, safety cables, lighting, and supplemental braking to flat tow your vehicle. The most popular compatible tow bar is the Falcon All Terain, # RM-522. This has non-binding arms which makes the setup very easy to connect/disconnect. For...

  • Best 4-Way Trailer Wiring Kit Recommendation for 2018 Jeep JL Wrangler
  • The best choice for 4-way trailer wiring for your 2018 Jeep Wrangler JL is the T-One kit part # 118786. Reason is it has higher amperage ratings so it would be more difficult to short out and because T-One in general just makes more reliable trailer wiring for vehicles.

  • Blue Ox Patriot and Tow Bar Recommendation for Jeep Wrangler with Blue Ox Base Plate Kit
  • The current version of the Blue Ox Patriot is the part # BLU37TR so that would be the Patriot to use. For a tow bar I really like the Blue Ox Avail part # BX7420 which has non-binding arms that make it easier to connect and disconnect from and has longer arms which I really like since it allows the towed vehicle to track better behind the tow vehicle. It also comes with safety cables too.

  • Which Trailer Hitch for 2018 Jeep Wrangler JL Has Best Clearance for Bike Rack to Fit Past Spare
  • We do have hitch extenders that you could possibly use to help get your bike rack out past your rear spare but the best solution is the trailer hitch part # e98856 instead of the # 13432 as this hitch has a longer hitch tube which puts the hitch accessory out further on the rear of the Jeep for better clearance. When this hitch is installed the center of it's hitch pin will only be 2-1/2 inches away from the outer edge of a factory sized spare. For a 7 inch hitch extender we have the...

  • Supplemental Braking System Recommendation for 2018 Jeep Wrangler JL
  • Trailer brake controllers are not used at all with flat tow supplemental braking systems. The InvisiBrake part # RM-8700 will fit your setup and work well but it would not interact at all with your current trailer brake controller. For this style of supplemental braking (permanent install) I prefer the SMI DUO part # SM99251 for a few reasons. The setup is proportional which means that it will apply a proportional amount of braking that it senses your tow vehicle applying to the towed...

  • Pro and Cons of Air Bags Versus a Weight Distribution System for a 2018 Jeep JL Wrangler
  • For your 2018 Jeep JL Wrangler, I recommend using a weight distribution system, the Husky Center Line Weight Distribution part # HT32215 for 2" hitch ball or part # HT32216 for 2-5/16" hitch ball. The main reason I recommend a weight distribution system over airbags like the Air Lift AirLift 1000 Air Helper Springs for Coil Springs part # AL60829 is because the weight distribution system has integrated sway control. Now, you may not think that because you have a light trailer that trailer...
