ReadyLIFT offers 2023 Ford F250/F350 Super Duty truck owners the necessary products to upgrade your current leveled or mild lifted suspension. Our 67-23350 Radius Arm Bracket Kit is derived from the products included in our new 3.5" series lift kit systems. An integral part of the 3.5" system are the new Radius Arm Drop Down Brackets that are designed to reposition the factory radius arms in the stock position in order to retain correct OEM suspension geometry.
