The ICON Vehicle Dynamics 4.5 - 7 Lift Extended Brake Line Kit for the 2017 - 2024 Ford F - 250F - 350 Super Duty is an excellent upgrade for the front of lifted Super Duty Trucks. These high - quality stainless steel braided brake lines feature an extended length to prevent over extending of OE brake lines on trucks with 4.5 - 7 of front lift or the requirement to bend factory hard brake lines to work with drop brackets during installation of the suspension system. Their direct bolt - in design bolts directly to the OE hard lines and brake calipers without any additional hardware required, making installation a breeze.
