Install Hotchkis Sport Suspension's Tubular Lower A-Arms on your 1958-1964 Chevrolet Impala for vastly improved handling and control thanks to revised suspension geometry. These TIG welded bolt-on arms have repositioned ball joints that increase caster up to +7 degrees when combined with the 1113U upper a-arms, resulting in enhanced stability and traction. Adjustable spring pockets offer minor ride height adjustment when using standard coil springs. For cars running air suspension, the a-arms are easily converted to bags using the optional 1113L-AB mounting kit. Finished in gloss black powder coat, the arms are ready to install and are complete with ball joints, bump stops, ride height shims, polyurethane coil spring locators and greasable, Delrin bushings. These a-arms are a must have for any tricked out Impala, or Biscayne.
