    appears to be a well made part. It actually works. we installed a disk brake kit from another supplier proportioning valve started leaking, this valve solved the problem and looks much better made. More like a oem valve

    Review by Jon McKenney from Newtown, Pa. on 10/26/2015
    Part fit was right on except for the switch connector. Had to re-use old switch. Could have cut top of switch if needed.

    Review by Tim from Tulare, Ca on 1/5/2015
    Overall good part, only complaint about it is that I had problems with one of the fitting hole threads not being machined all the way. I could not start one of my brake lines. I had to use a tap to finish the threads, after that, started and threaded just fine, no leaks. What after market part doesn't need to be modified!
