1970–1973 Mustang Big Bearing Front Spindles, or Conversion for 64-69 Mustang

Direct Replacement for 1970–1973 Mustangs

Original 70–73 Mustang spindles are notorious for being bent, worn, or heavily corroded after decades of use. Finding good used cores is expensive and time-consuming.

These spindles are:

• Forged for superior strength

• Particle tested for quality control

• E-coated for long-term corrosion resistance

They bolt directly in place of factory drum brake spindles, making them ideal for stock restorations, driver-quality replacements, or performance brake upgrades.

The result?
