Available in Dual or Single configurations, these Fox truck steering stabilizers reduce the vibration that you can get from oversize tires, bump steer or in extreme cases, death wobble. FOX 2.0 IFP smooth body shocks feature FOX's proven damping technology for better ride quality and control in all terrains, for a comfortable on-road ride and predictable on-road handling. Part of the reason Fox steering stabilizers dampen the impact so well is because they have a 5/8” hard chrome plated, heat-treated, alloy steel shaft. The internal floating piston (IFP) separates the shock oil from the high-pressure nitrogen-charged chamber, eliminating oil aeration.
