This is the left side only RockJock aluminum outer knuckle casting, bare, but fully machined. Knuckle is cast out of 206T6 aluminum for maximum weight savings, yet still retains superior strength. Accepts stock Ford 1 ton ball joints (ball joints NOT INCLUDED as picture shows!), and any stock Ford 1 ton unit bearing - as well as the Currie modified 1 ton unit bearings. Features of the knuckle include threaded bosses in the top of the knuckle for mounting Currie steel upper steering arms (sold seperately), a pad with threaded bosses on one of the edge faces of the knuckle that allow you to fab and install additional steering components, steering stops cast in the front and back side of the knuckle and adjustable stop bolt installed, and threaded bosses for mounting of radial-mount Wilwood Dynalite calipers. Polishing available for an extra cost. NOTE: These knuckles are only for use with Wilwood brakes with radial mount calipers only. Not for use with factory F-250/350/450 brakes.
