Product Details

Universal TriFlex™ NEXT Proportional Trailer Brake Controller (51146) by CURT®. Compatible with anti-lock brakes and cruise control, operates 2-8 brakes, automatic leveling and calibration. Automatically adjusts brake output when going up or down a hill, sensitivity adjustment for varying trailer loads or driving conditions. Mounting hardware included. Inertia-based brake control. Curt has everything you need to set up your car or truck to tow, starting with CURT hitches and accessories. Tow in comfort and safety with the proper gear, and make your life easier around the campsite or while traveling with CURT accessories.

Installation

It takes a lot of power to stop a moving trailer, especially when that trailer is hauling a heavy load. On RVs, flatbeds, livestock trailers and many other oversize haulers, manufacturers typically install trailer brakes to assist the tow vehicle in bringing such a massive amount of weight to a halt. But it takes more than a good set of brakes to make quick, efficient stops. It takes precision and the right amount of control. The crown jewel of CURT's brake control lineup is the TriFlex™. This proportion-based brake control features a compact size, a digital display and the ability to manage up to eight brakes at a time. The feature that sets the TriFlex apart from all others is its triple-axis motion-sensing accelerometer. This integrated circuit component allows the TriFlex to detect every motion of your vehicle and trailer with exact precision and to then apply the perfect amount of braking power for every situation. The TriFlex also automatically adjusts brake output when going up or down a hill and is compatible with anti-lock brakes and cruise control. It comes with a mounting bracket and hardware and can be mounted at various angles on your vehicle's dash. Best of all, like other CURT brake controls, the TriFlex is protected by a limited lifetime warranty. All CURT brake controls are designed to work with quick plugs so that they can readily plug into your vehicle's original equipment socket. They also include a mounting bracket and hardware for easy installation. A brake controller should be mounted somewhere on the dash of your vehicle, and CURT recommend putting it below the steering wheel, either on the right or left side of the steering column. This way the control will not block your view when driving, but it will remain accessible and visible when adjustment is needed.

Easy to Use, Does the Job.
I bought this because I lack the skills and energy to install a hard-wired controller and like the fact that I can use it on any properly wired vehicle. I found it very easy to use though overall.

Shipping
It took a long time for the wiring kit to get here. This not the fault of CARiD but rather of the manufacturer. I contacted CURT ,t5he manufacturer and they said the wire kit was in stock but it was back ordered for several weeks. and I had no way of connecting up the control. CARiD did a good job of keeping us posted on what was going on. Good job
