Description
Replace worn or hard-to-find factory spindles with a brand-new set of forged 1970–1973 Mustang–style spindles. Whether you’re restoring your original suspension or upgrading an earlier Mustang for improved strength and geometry, these spindles deliver the quality, precision, and durability you need all without the hassle of hunting down used parts.
DIRECT REPLACEMENT FOR 1970-1973 MUSTANGS
Original spindles from 1970–1973 cars are often bent, rusted, or worn after decades on the road. Finding a clean set can be time-consuming and expensive. These spindles offer a brand-new, high-strength solution with OE-style fit and finish ideal for stock restorations, performance upgrades, or replacing damaged originals. Each unit is forged for strength, particle tested for quality, and E-coated to resist corrosion for years to come.
UPGRADE FOR 1964-1969 MUSTANGS
These spindles are also a popular bolt-on upgrade for earlier 1964–1969 Mustangs. The 1970–1973 design features improved steering arm geometry, larger pin diameters, and more durable wheel bearings. Exactly what’s needed to handle today’s wider radial tires and higher grip levels. This upgrade sharpens steering response, improves durability, and provides compatibility with modern brake kits.
