Focus ST Rear sway bar

Your Focus ST

Pick your year to see what fits.

Every US Focus ST (2013–2018) is a hatchback with a 6-speed manual and the same 2.0L EcoBoost engine, so the same parts fit every year.

Why do it

A stiffer rear bar reduces body roll and helps the front-drive ST turn in with less understeer.

How to know it worked

Did this guide work for you?

Safety first

  • Park on flat ground, set the parking brake and chock the wheels.
  • Never get under a car held up only by a jack. Use jack stands.
  • Let the engine and exhaust cool first.
  • Disconnect the battery before unplugging electrical parts.
  • Wear safety glasses.
  • If something doesn't match your car, stop and ask a shop.

Follow your part's instructions and your service manual's torque specs.
