Steering stabilizers are shocks that help& absorb the jar and bump to your steering system. This action results in increased vehicle control under all driving conditions by reducing steering shimmy and driver fatigue. A stabilizer will also help improve tire wear and even provide better control in blowout conditions. Single stabilizers are ideal for 4WD and 2WD trucks, SUV's, vans, motorhomes and for use with tires up to 35".Dual setups are recommended for the aggressive off-roader and for large, oversized tires.
