If you are lifting your 4WD more than 1” then you need to seriously consider the change you are making on the caster. As you lift up your truck, you need to increase the caster and avoid that ‘wandering’ feeling. Upon fitment you will immediately notice a change in your vehicle resulting in more precise steering and minimised risk of tyre vibration. A variety of different options are available depending upon your lift and what ‘feel’ you want in your truck. There is not much difference in the ‘feel’ with fitting either S0549U or S0499R. Both bushings offer 2deg caster correction, and are voided to enable flexing and preventing bind up. You will find S0550U will give you a firmer feel, as these urethane bushings are not voided. S0551U is designed for the big lifts and offer 3deg caster correction.

Supplied complete with outer Shell that fits firm in the Radius Arm to avoid bushing movement under harsh braking conditions resulting in caster change.
