*1939-1941 Buick SR 40/60; 1939 LaSalle and Cadillac SR 61: state if lower, inner bushings are rubber or hex headed steel with grease fitting. Complete kit for 2 control arms These lower inner control arm bushings are the same as the ones included in our popular front end kits. These rubber bushings are made of much better rubber compounds than the original bushings, and are newly manufactured, not old NOS parts that have been sitting around for 40 or more years. Every front end rebuild involves the control arms in some aspect, so why not freshen them up to new with a set of control arm bushings? We also offer Upper Inner control arm bushings, tie rod ends, ball joints, pin kits, shaft kits, stab links, and king pin sets in our store separately from the front end kit.
