These extended brakes lines are designed for our 3" lift suspension systems. They are extended in length, Teflon-lined, stainless steel braided and Kevlar reinforced with an additional protective covering. Our brake lines are made up of 5 layers for optimum strength and every single one is pressure tested. We know our brake lines are used in extreme conditions and are getting hit, pulled on, etc. off-road so we cut no corners. They come with everything you need to install them to the OEM mounts and fittings. The Wrangler Rubicon and Gladiator are 37" in length. These are pressure tested to 4,500 psi and meet Federal D.O.T. MVSS-106 standards. Select your model since brake lines are different between the Sport, Sahara and Rubicon.
