Is the proportional valve in the fully up postion or should it be in the fully down position ?

I have a 3" lift kit and have installed the proportional valve extended bracket kit and have noticed the braking is spongier than it used to be . If someone has a good explainion on how this system works and how it should be setup that would be great!

the idea is to raise that arm the exact amount of rear lift that you have added. you will need before and after measurements to really do this right. but, if your brakes are really soft and the fronts lock up before the rears you can adjust it by moving the arm up via the OE threaded adjustment rod. Crank it up about 1/2" at a time and test it out trying to get your brakes to lock up. When you think you have it just right back it off a tad.
