16. New ductile iron knuckles come with the kit. These knuckles are CNC-machined and designed to retain the OE steering geometry. These are the narrow-track knuckles, which keep the track width of the front suspension close to stock but increase the turning radius. BDS also offers standard-track knuckles, which widen the front track slightly but retain the stock turning radius. The installation of these knuckles differs depending on which type of knuckle is being installed. The kit includes detailed instructions that outline the procedure for each.
