The Anti lift kit increases Caster by repositioning the rearward lower control arm suspension mounting height. A reduction in caster loss during braking was also aided through the low compliance bushing and offsetting the bushing for increased static caster angle. Which aids in the vehicle straight-line stability and reduction in steering effort through increased negative camber angle. The comfort version uses a softer bushing offering a more street friendly vehicle. It will transfer less noise and vibration into the vehicle while still giving you the benefits of increased caster. Adds approximately 0.5 degrees of positive caster.
