The JL Wranglers emergency brake lines are routed over the top side of the frame crossmember, we have found that with the articulation that a Rusty's Suspension offers, that these brake lines can be a limiting factor to get the maximum flex out of the vehicle. Re-routing the lines and installing the support is a simple bolt on installation. The support keeps the cables secure and safe from contacting other suspension or axle components. The support is laser cut steel and powder coated black, it offers rubber grommets to keep from any wear or chaffing to the cables.
