MOOG Chassis Products Coil Spring Set P/N:81071
MOOG Chassis Products 639 front coil spring set for the 1947-1951 Chevrolet Sedan Delivery and other vehicles supports the front end and absorbs road shock.
Worn or sagging coil springs can cause premature tire wear because the vehicle falls out of alignment. Before you replace the coil spring set, rule out worn tie rod ends, worn ball joints or an alignment problem, since any of them can also wear tires unevenly.
This front coil spring set fits the 1947-1951 Chevrolet Sedan Delivery, the 1954 Chevrolet 1500 and the 1950-1954 Chevrolet Bel Air, and a car takes one set. If your car is not named here, find your year and model in the "Vehicles it fits" section on this page.
