Our Totally Tubular™ Control Arm sets are designed to add 5° of caster while providing full wheel travel and minimal friction possible. They are made from thick tubing to eliminate distortion from welding and hard use. The bushings are made from self lubricating non-squeak patented plastic that will out last any rubber or urethane. The billet 4140-alloy steel cross shafts and sleeves are zinc plated for lasting performance. The sleeves have an interlocking design that prevents the hardware from ever working loose. Simple bolt-in installation with no modification required. They work with all factory and replacement power steering systems, and with or without O.E. bump stops. Note: Ball joints are included. Please specify year when ordering. Lower arms only work with end link style sway bar. Sold in Pairs. This item may be drop-shipped from the manufacturer and could take 2-4 weeks for delivery.
