    Review by Scott Thomas from , on 4/22/2018
    Fits just like factory proportioning valve only thing different was having to use adapters on 2 fittings to change sizes to fit the valve which y'all had already instructed me I would have to do thanks I will definitely buy again this is the second purchase anyway!!

    Review by Steve Lopez from , on 3/6/2017
    The web site indicated that I'd need to swap the front and rear lines and get adapters up at the master cylinder, but on my truck that wasn't quite right. In my case, the front supply line was correct, but the rear needed to be re-flared with a 7/16" flare nut. Other than that, install went fine and the shape fit all the line lengths. That was the only part of the brake system other than the hard lines that I hadn't replaced as new so I was glad to find it. Thanks!

    Review by David from Enid, OKLAHOMA on 10/10/2015
    After several weeks battling a brake issue, I diagnosed this valve as being faulty. Trying to find a replacement was almost impossible until I saw this ad. After great communication from their customer service, I ordered the part and it was shipped the same day. Great service, great price, fast shipping and quality parts. What else do you need, I will definitely use these guys in the future.
