This is what the 7.3 brakes should have been from the beginning. After replacing my third vacuum pump, and still having lackluster brakes to show for it, I decided to pull the trigger. Installation was straight forward with basic tools, and the instructions were great…And what a difference! First time I hit the brakes I almost came out of my seat. The truck stops solidly with little effort, and no more white knuckles. Thanks OBS Solutions for a great kit!
