CURT 51170 brake controller • Spectrum trailer brake controller • proportional trailer brake control • dash mount brake controller • electric trailer brake controller

The CURT 51170 Spectrum Trailer Brake Controller is a clean, modern proportional brake control designed for drivers who want smooth trailer braking without a bulky controller mounted under the dash. The Spectrum uses a separate hidden main module and a compact dash-mounted rotary knob, giving the cab a clean OEM-style appearance while still providing precise brake control for trailers with electric brakes.

Unlike traditional box-style brake controllers, the CURT Spectrum keeps the main control module mounted out of sight behind the dash. The visible control is a low-profile rotary knob with a push-button center and a 10-bar tri-color LED indicator. This allows the driver to adjust brake output, monitor braking activity, and access manual override while keeping the dash professional and uncluttered.

This controller uses a triple-axis accelerometer to detect vehicle movement and apply trailer brakes in proportion to the tow vehicle’s braking. That means smoother, more responsive stops compared to basic time-delay controllers. Automatic leveling and calibration also make setup easier, helping eliminate the need for constant adjustment after installation.

Designed for trailers with 1 to 3 axles, the CURT Spectrum 51170 is a strong option for towing utility trailers, enclosed trailers, car haulers, equipment trailers, livestock trailers, camper trailers, and other trailers equipped with electric brakes.
