🔥 1942–1948 FORD REAR RADIUS RODS — OEM 21A-4750 / 21A-4751 | STRAIGHT PAIR | HOT ROD 🔥

Ford's short rear radius rods — commonly called "hairpins" in the hot rod world — are one of the most sought-after suspension components for traditional pre-war and early postwar Ford builds. This is a straight, solid original pair, part numbers 21A-4750 (driver) and 21A-4751 (passenger), pulled from a longtime collector's estate.

These short arms are the correct OEM units for the '42–'48 Ford and a perennial favorite for builders using the stock Ford rear end in a traditional hot rod chassis. Finding a clean, usable pair in this condition is getting harder every year.
