3. Dexter E-Hydraulic Trailer Brake Actuator: Best for Hydraulic Brakes
The Dexter E-Hydraulic Actuator is the go-to choice for horse trailers equipped with hydraulic disc or drum brakes. In our research, it consistently delivers reliable hydraulic pressure, translating to strong and smooth stops even with heavy loads. Owner feedback highlights its durability, with many users reporting years of trouble-free service. The unit is robust and weather-resistant, making it suitable for outdoor mounting. However, it is not a standalone controller; you must pair it with an in-cab brake controller like the Prodigy P3 or Curt Spectrum. This adds to the overall cost and complexity.
This product is essential for trailers with hydraulic brakes, but if your trailer uses standard electric brakes, look elsewhere. It is best for owners who prioritize braking power and durability over simplicity, and who are comfortable with a two-component system.
- Designed specifically for electric-over-hydraulic brake systems.
- Rugged construction with corrosion-resistant coating.
- Provides consistent hydraulic pressure for smooth, powerful braking.
Pros: Excellent build quality and long service life.; Ideal for heavy horse trailers with hydraulic brakes.; Easy to install with standard wiring.
Cons: Not compatible with all-electric brake systems.; Requires separate brake controller in cab.
4. Hopkins Insite Smart Brake Controller: Budget-Friendly Smart Option
The Hopkins Insite offers a compelling mix of smart features and affordability. We found its inertial mode adequate for light to medium horse trailers, but it does not match the smoothness of a premium proportional controller like the Prodigy P3. The app is intuitive and allows you to tweak settings, but the time-based mode can feel jerky on steep grades. Owner feedback notes that the unit is reliable for occasional use, but some have experienced Bluetooth dropouts. The LED display is basic but functional.
This controller is best for budget-conscious owners who tow a small horse trailer infrequently and want smartphone control. If you tow heavy loads or need the smoothest braking for nervous horses, you may be better served by a higher-end proportional model. The Insite is a good value, but not for heavy-duty use.
- Smartphone app for setup and diagnostics (Bluetooth).

5. Draw-Tite Activator III Brake Controller: Reliable Workhorse
The Draw-Tite Activator III is a no-frills time-based controller that has been a staple for years. In our evaluation, it gets the job done for small to medium horse trailers, but the braking feel is less refined than proportional models. Owner feedback often mentions that it works well for flat terrain but requires frequent manual adjustment on hills. The LED bar graph is helpful, but the lack of a digital display makes precise setting difficult. Its build quality is solid, and many users report decades of use without failure.
This controller is a good choice for budget-minded owners who tow a lightweight trailer on mostly flat roads. If you frequently haul heavy horses or navigate hilly areas, the jerky braking could stress your animals, and you should consider a proportional controller. For simple, reliable, and affordable braking, the Activator III is a workhorse.
- Simple time-based operation with adjustable sync delay.
- LED bar graph indicates brake output level.
- Rugged construction with a proven track record.
Pros: Very durable and reliable for basic towing.; Easy to install and adjust manually.; Budget-friendly price point.
Cons: Time-based braking can be jerky, especially on uneven terrain.; No proportional mode for smoother stops.
6. Reese Towpower Pod Brake Controller: Compact and Simple
The Reese Towpower Pod is one of the most compact brake controllers on the market. We found its time-based operation adequate for very light trailers, but it lacks the finesse needed for a horse trailer of any significant weight. Owner feedback indicates that it works for occasional, short trips with small trailers, but many complain of jerky stops when the trailer is loaded. The rotary dial is intuitive, but the lack of feedback makes fine-tuning difficult. Build quality is acceptable for the price, but not as robust as heavier-duty models.
This controller is best for owners with a very small horse trailer (e.g., a single-horse bumper pull) who tow only short distances on flat roads. If you haul multiple horses or travel long distances, the braking performance may be inadequate and could compromise safety. For minimalists on a tight budget, the Pod is an option, but we recommend spending a bit more for a proportional controller.
- Ultra-compact pod design mounts anywhere.
- Simple rotary dial adjusts brake output.
- LED light indicates power and brake activation.
Pros: Very small footprint for tight dash spaces.; Straightforward operation with no complex menus.; Low cost entry point.
Cons: Time-based only, less smooth than proportional.; No digital display or advanced features.
7. Curt Echo Mobile Trailer Brake Controller: Wireless Portable Option
The Curt Echo Mobile is a unique wireless controller that eliminates the need for an in-cab unit. In our evaluation, it offers convenience for those who tow with multiple vehicles, but its performance is not on par with wired proportional controllers. The Bluetooth connection can be spotty, especially with metal trailers, and some owners report lag in brake response. The app is functional but requires you to mount your phone, which can be a safety concern. It is also only compatible with electric brakes, not hydraulic systems.
This controller is best for owners who need a portable solution for occasional towing with different trucks. However, for regular horse trailer use, the lag and reliance on a phone app make it less reliable than a dedicated wired controller. We do not recommend it for heavy loads or frequent towing. If you prioritize safety and consistency, choose a wired proportional model instead.
- Fully wireless, mounts on trailer tongue or battery box.
- App provides brake control and diagnostics.
- Works with electric brakes only, up to 3 axles.
Pros: No wiring to the cab, easy to move between vehicles.; Compact and portable.; App offers basic diagnostics.
Cons: Bluetooth range can be limited (up to 30 ft).; App-based control can be distracting while driving.
Frequently Asked Questions
What type of brake controller is best for a horse trailer?
Proportional brake controllers are generally best for horse trailers because they apply braking force smoothly and in proportion to your truck’s deceleration. This reduces jerky stops that can stress horses. Time-based controllers are less expensive but can be harsher. We recommend a proportional model like the Tekonsha Prodigy P3 for the smoothest ride.
Can I use a time-based brake controller for my horse trailer?
Yes, you can use a time-based controller, but it may not provide the smoothest braking, especially on hills or when stopping quickly. Horses can be thrown off balance by abrupt stops. If you tow only on flat terrain with a light trailer, a time-based controller may suffice, but a proportional controller is safer and more comfortable for your animals.
Do I need a brake controller for a horse trailer?
In most jurisdictions, trailers over a certain weight (often 3,000 lbs) are required to have functioning brakes, and a brake controller is necessary to activate them. Even if not legally required, a brake controller is highly recommended for safe towing, especially with horses, as it reduces stopping distance and prevents sway.
How do I install a brake controller in my truck?
Installation typically involves mounting the controller under the dash, connecting it to the vehicle’s battery, brake light switch, and ground, and running a wire to the trailer connector. Many modern trucks have a factory harness for plug-and-play installation. Always consult the vehicle and controller manuals. If unsure, a professional installation is recommended.
What is the difference between proportional and time-based brake controllers?
Proportional controllers use an accelerometer to measure deceleration and apply the trailer brakes in proportion to the tow vehicle’s braking. This results in smooth, natural stops. Time-based controllers apply the trailer brakes for a set duration after you press the brake pedal, which can feel more abrupt and requires manual adjustment for different loads. Proportional is generally preferred for horse trailers.
Our Verdict
After researching and comparing the top options, our top pick for most horse trailer owners is the Tekonsha Prodigy P3 due to its exceptional smoothness, reliability, and ease of use. For those who want smartphone integration and dual-mode flexibility, the Curt Spectrum is an excellent runner-up. Both provide the smooth, proportional braking that keeps your horses safe and comfortable.
