Steering Knuckles & Spindles

The steering knuckle—often called the spindle on solid-axle or older vehicles—is the cast or forged pivot point that carries the wheel hub or bearing assembly and connects to the upper and lower control arms, strut, and steering tie rod. It sets the foundation for camber, caster, and toe alignment, so a bent or worn knuckle quickly leads to uneven tire wear, steering pull, and unpredictable handling.

Whether you're replacing a damaged original on a daily driver or upgrading to a stronger forged piece for track use, our collection includes direct-fit knuckles machined to factory dimensions for bolt-on installation. Expect components that preserve correct suspension travel, Ackermann angle, and brake mounting geometry.

  • Forged or cast steel and aluminum constructions—common in OEM replacements and performance applications
  • Precision-machined mounting bosses for control arms, tie rods, and brake calipers
  • Sold individually or in pairs; some include wheel bearings, hubs, or ABS sensor rings where noted
  • Check the application guide for exact year, make, and model compatibility

When shopping, confirm your vehicle's configuration (RWD/FWD/AWD, suspension style, brake rotor diameter) to ensure the knuckle matches the original spindle length, bearing bore, and sensor provisions. If you're unsure, reach out to our team—we’ll help you find the right part the first time.
