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. This aids in the vehicle straight-line stability and reduction in steering effort through increased negative camber angle. The race version uses a harder bushing offering ultimate performance. This will transfer the most noise and vibration into the vehicle and is not recommended for the faint of heart. Adds approximately 0.5 degrees of positive caster. The center tube does not come installed and may require a press to install due to the tight clearances.
