Why do I need an adjustable caster rod for my classic Mustang?

Modern radial tires perform best with alignment specifications that differ from the original factory settings. This adjustable caster rod allows you to add positive caster, which improves steering return-to-center and makes the car feel more responsive, especially with radial tires.

What kind of bushings does this caster rod use?

This SPC adjustable caster rod features high durometer, OE-style rubber bushings. These are designed to protect the chassis mount from damage and provide a solid connection.

Do I need to buy two of these caster rods?

Yes, this adjustable caster rod is sold individually. You will need to purchase one for each front wheel to adjust the caster on both sides of your vehicle.

Product Details

If you're putting modern radial tires on your classic '64-'66 Mustang, you'll want to adjust the alignment specs. The original factory settings were designed for bias-ply tires, and radial tires perform best with more positive caster. This adjustable caster rod from SPC Performance is designed to give you that improved geometry. It helps promote better steering return-to-center and makes the car feel more responsive.

Stock strut rods on these early Mustangs are usually non-adjustable and can develop worn bushings. This wear allows for extra movement in the lower rod assembly, which hurts handling. SPC's adjustable caster rod uses high durometer, OE-style bushings to help protect your chassis mount. The design makes it straightforward to dial in the caster you need for better tracking and a more modern feel on the road. This part is sold individually, so you'll need one for each front wheel.

If you're looking to adjust camber as well, SPC offers a complete control arm kit. For this caster rod, you'll get the positive caster needed for improved tracking and modern geometry.
