• Enhanced steering weight and feel; the small caster change will weight up the steering slightly as you come off-center and the improved cornering grip delivers greater feel for the handling limit through the wheel.
• The caster offset bushings deliver only benefits with no negative impact on tire wear, comfort or unwanted handling behavior.
• SuperPro's polyurethane bushings are the culmination of nearly 5 decades of suspension expertise and development in Australia's harshest terrain.
