Spectrum Integrated Proportional Trailer Brake Controller

Spectrum Integrated Proportional Trailer Brake Controller The CURT Spectrum is an advanced proportional trailer brake controller designed to deliver smooth, precise braking while maintaining a clean, factory‑installed look inside your vehicle. Its unique two‑piece design features a compact dash‑mounted rotary knob with 10 tri‑color LEDs, while the main control module installs hidden behind the dash for a seamless appearance.

Using a triple‑axis accelerometer, the Spectrum senses vehicle movement in all directions, applying the exact amount of trailer braking needed for safe, controlled stops—whether on flat roads, steep grades, or during sudden braking. It supports 1–4 trailer axles (2–8 brakes) and is compatible with ABS, cruise control, PWM systems, and low‑voltage vehicles.
