      Does this include all 4 brake lines?

      • This Synergy Extended Front/Rear DOT Approved Brake Line Kit, Would only be two brake lines you will need to order an additional set to replace both your front and rear lines.

          My OEM lines were longer.

          These do not fit up to a 4in lift... maybe up to a 2 in lift. My stock OEM lines were longer.

          Work great with my 2.5 inch lift

          Works great, feels like a very well made product. Get what you pay for. Make sure you order 2 sets if youre wanting to do all 4 lines. Only comes with two lines.

          Great Brake Lines

          I have a 4" Teraflex lift and these fit front and rear great. I love Synergy products. I highly recommend these and all Synergy parts.

          SHORTER THAN STOCK.These will not help. They are 3" shorter than the stock ones. Now I have to pay twice to have them installed. Not Happy. Probably my fault for ordering the "EXTENDED" ones. I guess I should have measured them against the stock ones before I had them removed.

          Good lines great quality

          These lines are nice and easy to install. Look very high quality and should last a long time. Dump those oem lines...

          Do what they're intended for

          These brake line extensions were fairly easy to install and work as intended. Don't have to worry about them breaking when going over a rock or fallen tree

          Good Quality

          Glad I bought these with my 3.5" lift so that I didn't have to use the brake line relocation brackets that were included. Now i'm not afraid that my factory brake lines with over extend or break.

          tried and true

          I wanted some longer break lines prior to my Colorado trip. My oem were too short at full extension. After installing these my break pedal and stopping power feel better all the way around.
