The Pedders range of 4x4 eXtreme Upper Control Arm Kits are engineered to resolve the issues associated with raised height independent front suspension vehicles. When a vehicle is raised it can often disrupt the factory-set steering geometry which can cause Caster and Camber angles to be outside OEM specifications. This product is designed to maintain desirable geometry for lifted vehicles while giving clearance for increased wheel and tyre sizes. Pedders 4x4 eXtreme Upper Control Arms are manufactured from carbon steel tube for optimum strength and durability.
