    FAQ

    What vehicles does the 302717 kit fit?

    It fits 1978 to 1988 GM G-Body cars, including the Buick Regal, Chevrolet Malibu and Monte Carlo, Oldsmobile Cutlass, and Pontiac Grand Prix and LeMans. See the Vehicle Applications list for full year and model coverage.

    What is included in the kit?

    The kit includes double adjustable lower control arms with spherical rod ends (item 3027) and double adjustable Ultimate Arms upper control arms (item 3017).

    What does double adjustable mean?

    Both the upper and lower arms adjust in length, so the rear axle position and pinion angle can be set independently to suit the vehicle and its intended use.

    Is this kit made in the USA?

    Yes. UMI Performance manufactures this control arm kit in the USA.
