ReadyLIFT offers 2005-2016 Ford F250/F350 Super Duty truck owners the necessary products to upgrade your current leveled or mild lifted suspension. Our 67-2550 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. The 67-2550 Radius Arm Bracket Kit comes with our 67-2551 1.0" lower spring spacers which will easily allow owners with a 2.5" leveling kit or even our popular 2.5" Mild Lift kit to increase the lift height using the 1.0" lower spring spacers and radius arm drop brackets.
