  • To fit the Provider ST225/75R15 Radial Tire w 15" Steel Mod Wheel # TA37VR to the Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle # ASR3500S06 you need the Trailer Idler Hub Assembly # AKIHUB-655-35-EZ-K.

  • Which Curt T-Connector Fits a 2018 Jeep JL Wrangler
  • We do have a Curt T-Connector that fits a 2018 Jeep Wrangler JL but the part # C55124 that you referenced does not fit. Instead you need part # C56407 which tees in behind your tail lights and then draws power directly from your battery via the included black wire. The great thing about drawing power directly from your battery is that your vehicle wiring is completely protected in the event that something goes wrong with your trailer wiring. Attached is an installation video of this wiring...

  • 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...

  • Roof Top Tent Compatibility with Thule Aero Roof Rack on 2018 Jeep Wrangler JL
  • For a 2018 Jeep Wrangler JL hardtop, the Thule Rapid Gutter Feet for AeroBlade Crossbars - 5" High - Qty 4 # TH300R along with the Thule WingBar Evo Crossbar # TH711500 in silver or # TH711520 in black will fit. I also recommend the lock cylinder kit # TH450400 to secure the rack. This rack will have a capacity of 165 lbs so it will work well with a tent like the Yakima SkyRise HD # Y07437. These tents are designed so that they will work on a roof rack with a capacity of 165 lbs because...

  • 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...

  • No Power to 7-Way On A 2018 Jeep Wrangler
  • Then it is possible that your 2018 Jeep Wrangler is not equipped with a trailer tow package. I did take a look at the owner's manual for the Jeep and F37 is the correct fuse placement if the Jeep is equipped according to the manual. Did you just install the 7-Way plug? If so, you may need to have the towing functions activated at the dealership. This is a fairly common issue.

  • 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....

  • 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...

  • Will the Hollywood Racks SR1 Fit a 2018 Jeep JL Wrangler with 285/70-17 Spare Tire
  • Yes, the Hollywood Racks SR1 2-Bike Carrier part # HRSR1 will fit the 285/70-17 spare tire on your 2018 Jeep JL Wrangler as it works with tires up to 15" wide and the 285/70-17 spare tire you have is only 11.2" wide. The u-shaped bar you are referring to is adjustable from 7-3/4" to 13-1/2" which is what allows it to fit different width spare tires. For reference, I have attached a photo of this carrier used on a 265/70-17 spare tire which is only around an 1" smaller in width than your...
