The off-road mode is a unique feature of the Redarc Tow-Pro Link. In this mode, the brake controller will apply your trailer's brakes with a preset amount of power, independent of what your tow vehicle is doing.
This is ideal for off-roading or challenging conditions. Set the power low if you're towing through sand or mud so that the trailer doesn't stop with too much force and act as an anchor. If navigating a steep descent, set the power to a higher level to ensure that the trailer doesn't push against the tow vehicle.
Proportional braking means that your trailer brakes mimic your tow vehicle's brakes. If you slam on the brakes in your vehicle, your trailer brakes will activate with the same intensity; if you brake lightly, your trailer brakes lightly too. The trailer's braking is in proportion to your vehicle's braking. This saves wear and tear on the tires and the brakes on both your vehicle and trailer.
The Tow-Pro Link uses an internal 6-axis accelerometer and gyrometer to sense how your vehicle is braking so it can send the right amount of braking power to your trailer. It measures the inertia of your tow vehicle and activates the trailer's brakes to slow at the same rate. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.

Easy Install, Smart Design, Minor Cord Quibble
I recently purchased the Redarc off-road rated trailer brake controller and have been very happy with it. Even as an etrailer employee, I was genuinely excited to see this product hit the market, and after using it, it hasn’t disappointed.
Installation was about as easy as it gets. The physical install was quick and straightforward with no splicing, cutting, or fishing for wires. I mounted the control box to the frame above my spare tire, which keeps it protected from road debris and completely out of the way.
Calibration took a couple of short test drives to dial in, which has been my experience with other brake controllers as well. Once set, braking has been smooth and consistent.
One feature I really appreciate is the removable controller. When I’m not towing, I can store it in my center console. I also like that I don’t have to rely on my phone for brake control. I’ve used the Curt Echo before, and by comparison, using a phone for braking always felt a bit inconvenient.
That said, the app still adds real value. Being able to test my trailer lights from my phone is a huge plus and saves a lot of time compared to the usual back-and-forth or needing a second person. It’s probably my favorite non-braking feature.
My only downside is the corded controller. I’d love to see a future version with a USB-C connection instead of the standard USB.
Overall: 10/10, would buy again.
I like the Redarc Tow-Pro Link because the main module installs out of sight behind the 7-way, which means no bulky controller hanging under the dash. I also like that it uses Bluetooth, which means there’s no reaching under the dash to adjust gain. If your vehicle has Apple CarPlay or Android Auto, you can make adjustments right from the screen. If not, the included remote works just as well, which is especially convenient in states where it’s illegal to have your phone out while driving.
The sway control feature really stands out to me. It lets you press a button if the trailer starts swaying from wind or passing traffic, and the controller applies the trailer brakes only to help pull everything back in line. It takes the guesswork out of reacting in the moment and settles things down quickly without locking up the brakes. I also like having Off-Road Mode for gravel or loose surfaces.
This is a great option if you want a clean install without giving up strong, reliable braking.
This was super easy to install. Works great on my 2025 Ram 1500 3.6 pulling 6000# 2 axle Keystone Premier. Nice to see it on the app, CarPlay and the easily hidden remote. Can unplug and put away the remote when not in use. I didn’t have my trailer accessible when I first tried installing it so just know you can’t do any set up without the trailer connected.
So far I have hooked everything up, which was very easy. My trailer is currently out of state but looking forward to seeing it work.
It looks very well made and nicely packaged. It was super easy to install and set up. The remote is nice but I especially like that i can control it through my phone or vehicle screen.
Works great!
