How to Flat Tow a Jeep Wrangler (Step-by-Step)
- Every Jeep Wrangler JK and JL with a two-speed transfer case is approved for flat towing — no drivetrain modifications required.
- A complete jeep flat tow setup costs $1,500–$3,000 installed and requires five components: tow bar, base plate, safety cables, wiring harness, and a supplemental braking system.
- The Wrangler weighs 4,200–4,600 lbs, making a supplemental braking system legally mandatory in nearly every U.S. state and all Canadian provinces.
- Maximum flat tow speed is 65 mph per Jeep's owner's manual — no per-day mileage limit applies.
- JL and JK models use the same tow procedure but differ in ignition method and base plate design.
The Wrangler has ranked #1 or #2 on Good Sam's annual flat-towable vehicle list year after year. If you've just bought a Wrangler or you're pairing one with a new motorhome, this guide walks you through every step — gear, procedure, legal requirements, and the JK-vs-JL differences that actually matter.

Can You Flat Tow a Jeep Wrangler?
Yes, every Jeep Wrangler with a two-speed transfer case is factory-approved for flat towing. Jeep's owner's manual explicitly permits dinghy towing — all four wheels on the ground — for both JK (2007–2018) and JL (2018+) models, with both manual and automatic transmissions. No special drivetrain modifications are needed. That factory approval is exactly why the Wrangler is the most popular dinghy tow vehicle in North America.
What the Wrangler can't do: you cannot flat tow a 2WD Wrangler Sport with the standard single-speed NV241 transfer case on older JK builds — confirm your transfer case has a true neutral setting before you assume you're cleared. If your Wrangler has a command-trac (NV241) or rock-trac (NV241OR) transfer case with a marked "N" on the selector dial, you're good.

What Do You Need to Flat Tow a Jeep Wrangler?
A complete jeep flat tow setup requires five components — skip any one of them and you're either breaking the law or risking drivetrain damage.
1. Base Plate Kit The base plate bolts directly to the Wrangler's frame behind the front bumper and gives the tow bar a solid attachment point. Base plates are model-specific — a JL base plate will not fit a JK due to the redesigned front fascia and frame geometry on the 2018+ generation. Brands like Blue Ox and Roadmaster both make Wrangler-specific kits; expect to pay $300–$500 for the plate alone.
2. Tow Bar The tow bar connects the base plate to the motorhome's receiver hitch. For a Wrangler, you need a tow bar rated for at least 5,000 lbs gross trailer weight — the JL Unlimited tips the scales at 4,600 lbs, so you want margin. The Blue Ox Avail and Roadmaster Falcon are two common choices in this weight class. Self-aligning tow bars are worth the extra cost; they let one person hook up without precisely lining up the rig.
3. Safety Cables Two independent safety cables attach from the Wrangler's frame to the motorhome's receiver. Federal Motor Carrier Safety Administration (FMCSA) cargo securement standards require crossed safety chains on towed vehicles — cross the cables under the tow bar so the Wrangler's tongue can't drop to the pavement if a connection fails.
4. Flat Tow Wiring Harness (Diode Kit) The wiring harness taps into the Wrangler's tail-light circuit so the motorhome's brake signal and running lights carry through to the Wrangler. A diode-based kit (rather than a simple T-harness) isolates the circuits and prevents backfeed that can blow fuses or damage the Wrangler's BCM. Budget $80–$150 for a quality diode kit. Some owners hire an electrician for this step — it's the fussiest part of the install.
5. Supplemental Braking System More on this in its own section below — but know that it's not optional if you're towing in any U.S. state or Canadian province with a weight threshold below 4,600 lbs. The Wrangler will exceed virtually every threshold.
Real-world budget example: Say you're buying new. A Roadmaster Falcon tow bar ($650), Sterling base plate for a JL ($425), Roadmaster diode kit ($110), safety cables ($45), and an RVibrake3 portable braking unit ($700) puts you at roughly $1,930 in parts before labor. Professional installation typically adds $400–$600, landing you near the $2,500 midpoint of the industry average. Compare that to shipping a Jeep on a trailer using our DIY car trailer tips guide — the flat tow setup pays for itself quickly.
How Do You Put a Jeep Wrangler in Flat Tow Mode?
Putting a Jeep Wrangler in flat tow mode means getting both the transmission and the transfer case into neutral — in the right order — so the drivetrain spins freely without pressurizing the transmission's hydraulic circuit. Do this wrong and you can cook the transmission on the first stretch of highway.
Step-by-step procedure (JL Automatic — 8HP75 8-speed):
- Park on level ground. Apply the parking brake.
- Start the engine and let it idle — the transmission must be warm enough to shift.
- Shift the transmission selector to N (Neutral).
- Shift the transfer case to N (Neutral) using the floor-mounted selector dial or lever. You'll feel a slight clunk.
- Press the Start button twice without pressing the brake pedal — this puts the JL in ACC mode, which keeps the steering column unlocked without running the engine.
- Release the parking brake.
- Confirm the steering wheel turns freely.
- Connect your tow bar, safety cables, and brake system before the motorhome pulls forward.
JK procedure (2007–2018, key ignition):
Same steps, but at step 5 you simply turn the key to the ACC position rather than a keyless press. Leave the key in ACC — removing it locks the steering column on most JK trims.
One common mistake: shifting the transfer case before the transmission. If you put the transfer case in neutral first with the transmission still in Park, the internal gear locking pawl in the transmission fights the transfer case shift. Always transmission neutral first, then transfer case.

Do You Need a Braking System to Flat Tow a Jeep Wrangler?
A supplemental braking system is legally required in nearly every U.S. state when towing a vehicle over a specified weight threshold — and the Jeep Wrangler, at 4,200–4,600 lbs, clears that threshold in virtually every jurisdiction. According to state DOT regulations surveyed by RV industry groups, 47+ states have supplemental brake requirements with thresholds ranging from 1,000 to 4,000 lbs. All Canadian provinces require one regardless of weight.
Beyond legality, the physics argument is straightforward. A Class A motorhome braking at 60 mph with a 4,400-lb Wrangler pushing from behind stops 40% longer than with a synchronized braking system, per SMI Braking's published testing data. That's not a margin you want to test in mountain traffic.
Two popular options:
- InvisiBrake (Demco): Permanently mounted under the Wrangler's dash; activates automatically when the motorhome brakes. Invisible to passengers, no setup per trip.
- RVibrake3: Portable unit — moves between vehicles, sits on the floorboard, uses a motion sensor and Bluetooth monitoring. Easier if you flat tow multiple vehicles.
If you're towing through Colorado, Utah, or Montana — states with steep grades and mandatory supplemental brake rules — a permanent unit like the InvisiBrake is worth the extra install cost. Our supplemental braking systems guide compares the top units in detail.
What Is the Maximum Speed for Flat Towing a Jeep Wrangler?
The maximum flat tow speed for a Jeep Wrangler is 65 mph, as stated in Jeep's owner's manual for both JK and JL generations. There is no per-day mileage limit — you can tow from Florida to Montana in one stretch if your motorhome driver has the stamina.
That 65 mph ceiling matters in practice. On Western interstates posted at 75–80 mph, you're the slow lane. Plan your fuel stops and passing opportunities accordingly. Also note that in California, per Vehicle Code §22406, vehicles towing another vehicle are capped at 55 mph regardless of the posted limit — so even though Jeep approves 65 mph mechanically, state law overrides that on California highways. Texas and Nevada impose no such restriction; you can tow at the posted limit.
In crosswinds or mountain descents, back off regardless of the speed limit. The Wrangler's flat, boxy profile catches side wind more than a car, which can create trailer-sway-like oscillation at the back of the motorhome at sustained highway speeds. Use your motorhome's exhaust brake or engine brake on long downhill grades — don't ride the service brakes.
Can You Flat Tow a Jeep Wrangler With an Automatic Transmission?
Yes — Jeep Wranglers with automatic transmissions are fully factory-approved for flat towing. This includes the 4-speed (42RLE in older JK trims), the 5-speed (W5A580 in some JK trims), and the 8-speed 8HP75 used in JL models. The key is that both the transmission and the transfer case must be in neutral simultaneously before towing begins.
This is genuinely unusual. Most automatic-transmission vehicles can't be flat towed because their transmission oil pumps only circulate fluid when the engine is running — tow them with the engine off and you burn up the clutch packs within miles. The Wrangler's two-speed transfer case bypasses this problem entirely: with the transfer case in neutral, the transmission's output shaft is effectively disconnected from the drivetrain, so it doesn't rotate during towing regardless of what the wheels are doing.
If you own a non-Wrangler Jeep — a Cherokee, Grand Cherokee, or Gladiator — the flat tow approval status varies significantly by year and trim. Our flat tow compatible vehicles guide has the full breakdown.
What's the Difference Between Flat Towing a JK vs. JL Wrangler?
The flat towing procedure for JK and JL Wranglers is nearly identical, but four differences are worth knowing before you buy equipment or prep your rig.
| Feature | JK (2007–2018) | JL (2018–Present) |
|---|---|---|
| Ignition method | Turn key to ACC | Press Start twice (no brake) |
| Base plate compatibility | JK-specific fit | JL-specific fit (not interchangeable) |
| Transfer case selector | Traditional lever or dial | Floor-mounted rotary dial |
| Automatic transmission | 42RLE (4-speed) or W5A580 | 8HP75 (8-speed) |
| Max flat tow speed | 65 mph | 65 mph |

The most common mistake when switching from a JK to a JL is reusing the old base plate — it won't fit. The JL's front fascia and bumper mounting points were redesigned in 2018, so even if your old Blue Ox or Roadmaster tow bar is still rated and functional, you need a new JL-specific base plate. Budget an extra $400–$500 for that swap.
The 8-speed 8HP75 in the JL shifts more smoothly into neutral than the older 42RLE, which sometimes requires slight rocking of the vehicle to fully disengage. If your JK resists shifting into transmission neutral, gently roll it forward six inches and try again.
