The Best Trailer Brake Controller For A Jeep Gladiator
Switch blanks instead of dash space, a cab that sometimes has no roof, and a 7,700 lb tow rating. The Gladiator rewards a different controller than a pickup does.

Quick picks
The same brake rubric as the main roundup — braking control (30%), install effort (25%), adjustability (20%), feedback (15%), price (10%) — reweighted for a cab with switch blanks, no spare knee room and occasionally no roof.
| # | Product | Best for | Score | Price |

| 1 |  REDARC Tow-Pro Elite Electric Trailer Brake Controller Kit Sold as a vehicle-specific kit with a dash knob that looks factory and two braking modes, so you can switch from proportional to user-controlled on a loose surface.

| 2 |  CURT Echo Mobile Bluetooth Trailer Brake Controller, 51180 Plugs in between the truck's 7-way and the trailer plug and is controlled from a phone, so there is nothing to mount and nothing to wire — the only controller here you can move between vehicles in a minute.

The short answer
A Gladiator is a 7,700 lb-rated tow vehicle in a Wrangler’s cab, and that combination is the whole story of this page. You are towing a real trailer — a 5,000–7,000 lb travel trailer is squarely in range — from an interior that has no flat lower dash to bolt a box to, and that a lot of owners open to the weather.
First: check whether yours already has one
Unlike the Tacoma, this is a check worth making. Jeep has offered an integrated trailer brake controller on the Gladiator as part of the heavy-duty or Max Tow equipment on some model years and trims. If yours has it, you will find a trailer brake gain control in the cab and a trailer brake section in the instrument cluster menu — and you do not need anything on this page.
- 1
Look for a gain control in the cab
A factory controller has a physical adjustment, separate from the trailer light switch. If there is a dedicated trailer brake knob or switch, you have one. - 2
Check the cluster menu
Scroll the driver information display for a trailer brake menu with gain settings. A truck without a factory controller has no such menu. - 3
Check the window sticker or build sheet
Look for the trailer tow or Max Tow package and whether an integrated brake controller is listed in it. The 7-pin connector alone does not mean you have a controller — it only means the trailer brake circuit exists.
The common mistake
What to look for in a Gladiator specifically
Switch blanks are an asset, flat dash is not. The Gladiator’s center stack and lower dash carry blank switch positions intended for accessory controls. A controller that uses one of those for a knob and hides everything else is working with the interior instead of against it. A big angled box is not: there is nowhere good to put it, and whatever you choose will be in a knee or in the way of the floor-mounted storage.
Weather, if the top comes off. This is a real consideration that does not come up on any other tow vehicle. A controller face designed for a sealed cab is not designed for an open one. Hidden electronics with a single sealed knob, or a controller that lives outside in the trailer socket, both handle this better than a box with a display and buttons.
Proportional braking at 6,000-7,000 lb. At the top of the Gladiator’s range the trailer is a large fraction of the combination, and the quality of brake modulation stops being a comfort question. Proportional vs time-delay explains the difference; all four picks here are proportional.
Harness fitment for your model year. A vehicle-specific plug-in harness turns the install into a connector job. Availability and part numbers change by year and by whether the truck has the tow package, so verify against your own VIN or model year rather than trusting a general fitment claim.
| Controller | What is visible in the cab | Weather exposure |
|---|---|---|
| REDARC Tow-Pro Elite | One small round knob in a switch blank | Low — sealed knob, electronics hidden |
| CURT Echo | Nothing — it lives in the 7-pin socket | None in cab; unit is outside by design |
| CURT TriFlex Next | A compact box with a display | Moderate — plan the position |
| CURT Spectrum | A larger box with a prominent knob | Moderate — plan the position |
The honest trade with each
Hidden knob (Tow-Pro Elite)
- Looks factory and survives an open cab
- Two modes — proportional for highway, user-controlled for off-road descents
- Most involved install of the four
- Costs the most
- No display, so no numeric feedback
Socket-mounted (CURT Echo)
- No install, no drilling, nothing in the cab
- Moves between vehicles — useful if you also tow with something else
- Your phone becomes part of the braking interface
- No physical knob to grab mid-stop
- Must be unplugged or left with the trailer
The Tow-Pro Elite’s second mode deserves a mention because it is genuinely relevant to a Gladiator rather than marketing. In user-controlled mode the knob sets a fixed trailer brake level rather than following vehicle deceleration, which is the behavior you want on a long loose descent where you are managing the whole combination with the trailer brakes rather than reacting to how hard the Jeep is stopping. On a Tacoma that mode is a curiosity. On a Gladiator being used as a Gladiator it is not.
What this ranking is, and is not
We have not fitted these controllers to a Gladiator. What is above is a reading of each maker’s published specifications and fitment data, current retailer listing data read automatically, and what owners consistently report — presented as reporting, not as our own testing. Verify harness fitment for your model year with the manufacturer. The rubric is published on how we pick.
What to remember
- Check the cab and cluster menu first — some Gladiators have a factory controller, and a 7-pin socket alone does not mean yours does.
- Switch blanks make a knob-only install the tidiest option in this cab.
- If the top comes off, hidden electronics or a socket-mounted controller handle it better than a box with a display.
- All four picks are proportional. At 6,000-7,000 lb that is not optional.
- Verify harness fitment by model year rather than trusting a general claim.

Common questions
On some years and trims, with the heavy-duty or Max Tow equipment. Look for a gain control in the cab and a trailer brake menu in the cluster. A 7-pin socket on its own is not evidence — it only carries the circuit.
In a blank switch position. The control module hides behind the dash and only the small round knob shows, which is why the result reads as factory rather than as an add-on.
Yes — a socket-mounted controller like the CURT Echo needs nothing mounted, drilled or wired. The trade is no physical knob and remembering to unplug it.
There is no universal number. Set it low, make repeated 20 mph stops with the loaded trailer, raise in small steps until the trailer contributes without locking, and reset it when the load or the weather changes.
