The ReadyLift 4.5" lift kit for the Ram 2500 was designed to ensure factory ride quality and handling are not compromised. Retaining the factory coil springs and using the laser cut steel front and rear coil spacers ensures this. Upgrading to a 35" tire becomes more economical using this method. Your Ram can look great without having to sacrifice ride quality.Kit Components4.5" Front coil spring spacers2.5" Rear coil spring spacersRadius arm drop bracketsFront track bar relocation bracketRear track bar relocation bracketLonger sway bar end linksSway bar drop bracketsBump stop extensionsFront and rear shock extensionsKit FeaturesRetains factory-like rideDurable satin black powder coat finishMade in USAAllows the following tire/wheel comboMax 37 on up to -18 offset wheel
