Check the listing for details. SuperPro SPF4010K Front Lower Control Arm Bushing Kit. Condition: New. Listed at 199.99 USD. Control arm bushings form the vital pivot and link between all core suspension components. Worn bushings allow significant deflection and movement leading to slower Reponses, a sloppy drive, irregular and excessive tire wear and diminish every facet of the way your vehicle drives. The wear is accelerated and the impact of worn bushings is even greater in upgraded trucks and SUVs where the higher weight and impact of items like larger wheels and tires all work the bushings harder. SuperPro's polyurethane bushings are the culmination of nearly 5 decades of suspension expertise and development in Australia's harshest terrain. Designed with durability as a paramount feature we also bring ride and passenger comfort to the forefront of our development.
