Easy to order easy to install. Perfect fit!

Works well but changed fitting

Works great and quality is good. Only frustration is they changed the outer diameter of the fittings and they barely fit through the passages drilled in my trailer (which is also a pacific trailer). It somewhat crushes the light wiring, hopefully it doesn’t cause lightning issues down the road due to compromised wiring.


I ordered a brake line on line expecting it to ship to my address. After a couple weeks I called in and was informed that the part was not shipped but sitting in the will call bin. The sales person was very helpful and my part was delivered shortly after my call. I would recommend that the website be updated to make the shipping choices more transparent. by the way whats with the ? its almost unreadable.
