These TeraFlex DOT approved stainless steel braided brake lines are designed for your JK, and ad the finishing touch to the big brake kit. Replacing the OEM rubber hose with Teraflex brake hose reduces brake hose expansion for more consistent braking and a firmer pedal feel. These are a direct bolt-on replacement and come in pairs. These brake lines measure longer than stock for additional suspension travel(30" long). All stainless brake lines are made to MVSS-1006 specifications.
