10 Best Electric Brake Controllers 2026 in the United States

The Tekonsha 8507120 Brakeman IV is a time-delay electric brake controller designed for trailers with 1 to 4 axles, making it suitable for light to medium towing jobs. It supports a wide range of vehicles including Ford, GM, Chevy, Dodge, RAM, Toyota, and Jeep, which is great if you own one of these popular brands. Its time-delay braking applies power gradually over a set time, which works well for basic towing but may not offer the smoothest or most responsive braking compared to proportional controllers.

Installation is fairly easy thanks to a Plug & Play port, though the wiring harness must be purchased separately, which adds to setup steps and costs. The unit’s compact design lets you mount it almost anywhere within driver reach, and the digital display is straightforward, showing brake power levels and connection status with clear red and green lights. You can also manually apply the trailer brakes using a lever, which is helpful for controlling stopping power in tricky situations.

The Brakeman IV covers essential features and supports up to 4 axles (8 brakes), but it doesn’t offer advanced adjustable braking curves or proportional braking that some higher-end models have. If you are looking for a reliable, easy-to-use brake controller for lighter hauling needs with simple installation, this model is a solid choice. For those who require smoother braking performance or more customization, other options might be more suitable.

The Tekonsha 90160 Primus IQ is a proportional brake controller ideal for trailers with 1 to 3 axles. This means it adjusts the braking power in proportion to the vehicle's braking, offering smoother and safer stops. It features a Plug-N-Play port for easy connection with 2-plug adapters, although it's worth noting that a T-connector, which is essential for installation, is sold separately.

The installation is made simpler with the included snap-in dash mounting clip and hardware, but some users may still find it somewhat complex if they're not familiar with vehicle wiring. The digital LED readout is a useful feature, providing clear diagnostic information and illuminating when issues occur. Additionally, the controller works proportionally in reverse, which is a handy feature when maneuvering a trailer.

The Boost feature is another plus, allowing for increased initial braking power when needed, which can be particularly useful in heavy braking situations. However, users should be aware that the product has been available since 2007, so while it is trusted and popular, it might lack some of the newer technological advancements found in more recent models. The controller's universal fit and smooth exterior design add to its appeal, making it a good choice for a wide range of vehicles and setups. The Tekonsha 90160 Primus IQ is a reliable and user-friendly option for those looking to enhance their trailer braking system, though it may require an additional purchase for full installation.

The CURT 51170 Spectrum Electric Trailer Brake Controller is a proportional brake controller, providing smooth and responsive braking by matching the intensity of your vehicle's brakes. This makes it a reliable and predictable option for towing. It supports multiple axles, useful for larger trailers. The controller integrates seamlessly with your vehicle's dash for a factory-installed look, with user-friendly controls, including a simple knob for monitoring and adjusting brake settings easily.

A standout feature is the hidden main module, which keeps the dashboard uncluttered. The triple-axis accelerometer ensures intelligent braking by detecting motion in three planes and adjusting braking power accordingly, enhancing safety especially on hills. However, installation might be challenging as the module needs to be mounted out of sight, possibly requiring professional help.

The exterior finish is painted, and the unit is constructed from durable aluminum. This brake controller is compatible with modern vehicle systems, including low-volt, PWM, ABS, cruise control, and electric over hydraulic brakes, making it versatile. Potential users should be prepared for a possibly complex installation process.
