Factory Installed Integrated Brake Controllers

I have had the IBC on three trucks now and they work flawlessly. Just set it and forget it as it is totally proportional to the brake pedal pressure you apply. I set my F250 at level 9 towing a 10,000 lb trailer and have never had to adjust it. Because they work so smoothly, I at first thought it was not working the first time I used one. Not grabby at all, just nice smooth braking action. Highly recommend.
