Upgrade the braking system in your lifted Jeep Wrangler JK with the Rough Country Front & Rear Stainless Steel Brake Lines. These heavy-duty brake lines feature a braided stainless-steel exterior with an interior Teflon layer. The outer stainless-steel layer keeps the brake lines from expanding like the factory rubber lines. These brake lines are extended and are meant for use with 4-6in of lift.
