Trailer brake controllers send signals from your tow vehicle to your trailer's electric brakes, giving you proportional braking that responds to how hard you press the pedal. Without a properly set brake controller, your trailer either brakes too aggressively (causing skipping tires) or too weakly (making your tow vehicle do all the work). We carry time-delayed controllers for budget setups and proportional controllers that sense your vehicle's actual deceleration.

What to Know Before You Buy

• Proportional controllers provide smoother, more responsive braking than time-delayed units—worth the upgrade for frequent towing.
• Your tow vehicle needs a brake controller wiring harness—some newer trucks have it pre-installed, others require an add-on kit.
• Controller mounting location affects usability—dash-mount units are easy to reach; under-dash mounts save space but are harder to adjust.
• Wireless controllers eliminate the wiring harness requirement and work with vehicles where traditional installation is difficult.
