    own a older Jeep? YOU NEED THESE GUYS

    drove 500 miles round trip to get an OEM crossover brake line for JKU 2011. ONLY dealer, supplier that had one. Checked against VIN all good ... Under the Jeep and I discover that although the tube was all the right bends, right length the FITTING to the crossover connection was the wrong size. Can not find brake fittings for my Jeep so I now have hydraulic flare tool and enough tube, connections and clips to keep my Jeep stopping when it needs to. Fast efficient and good products at decent prices PLUS they have the stuff !
