Fitment & Compatibility
For the exact CPP two-inch drop spindle installation shown in DS-1318, using casting CP30102 on the listed Tri-Five Chevrolet applications. A 1957-only Del Ray row does not extend to other Del Ray years, and no stock-spindle fitment is implied. Six-piston Superlite 6R calipers work with 14.00 × 1.10-inch rotors, separate hats and aluminum hubs. Bearings, seals and 1/2-20 studs are included; the hubs offer 5 × 4.50/4.75-inch wheel patterns. Flexlines remain separate and need the correct ends, length and steering clearance. Verify the original car's modifications and the wheel drawing, with nominal 18-inch minimum wheel guidance.
Listed models: Bel Air; Nomad; One-Fifty Series; Sedan Delivery; Two-Ten Series; Del Ray. See the supplied table below for each year, submodel and equipment condition.
