Not all spindles and wheel hubs are built the same. Even within the same year, the V8 spindles were typically stronger and more durable than those used on six-cylinder models. The good news is that swapping out your spindles for those from a different year or model is a popular upgrade that opens up possibilities for more performance improvements.

Getting wheel hubs and spindles that are durable is important. Since this part combines your suspension, steering, brakes, and wheels, you want it to be more than capable of holding up. That's why many people opt to upgrade to the options from performance editions. Knowing that a part was installed on an SVO or Shelby gives you the confidence to know it can handle at least that much horsepower. It's also helpful if you're looking to add the brakes or wheels from those editions.

The wheel’s spindle is what connects to the car’s control arms. Your Mustang’s front upper control arms, front lower control arms, and rear control arms are what link the wheels to the suspension. If you’re replacing any of these parts, it makes sense to check your spindles and hubs as well. A worn spindle will worsen handling, making your vehicle less safe to drive.
