Fitment & Compatibility

Use the individual Caprice, Impala, Biscayne and Bel Air application years and confirm the original drum spindle. DS830 defines hub bearing assembly and alignment; the new wheel position must be checked against fenders and suspension. Wheel mounting faces that extend beyond the hub diameter require the specified spacer. Do not treat the nominal 14-inch wheel minimum as a fit guarantee: measure barrel and spoke clearance. Hydraulic hoses and any required chassis connections are additional installation items.

Check the individual year, model, submodel and equipment conditions in the fitment table below before ordering.
