Simplify a worn strut repair with the Monroe Quick-Strut 172243 Front Left Suspension Strut and Coil Spring Assembly, a fully assembled, ready-to-install unit that drops in as a direct-fit replacement for the 2003 Subaru Baja and 2000-2004 Subaru Outback. This front-left assembly arrives fit-checked and ride-tested with the coil spring, upper strut mount, and strut preassembled — so there's no need for a spring compressor during installation. See the Buyer's Guide tab for engine-level fitment.

  • Complete, one-unit repair: Includes the components needed for strut replacement in a single fully assembled unit for a quicker, safer install.
  • Restores ride height: The application-specific coil spring is calibrated to the OE design to help restore ride height and support the vehicle's weight.
  • Vehicle-specific design: Application-specific coil spring, mount, and strut designs are engineered for ride and handling matched to this vehicle profile.
  • Maintains control: Helps reduce body sway, vibration, and road harshness before it reaches the cabin, and the premium upper strut mount supports smooth steering.
  • Rust resistance: A protective coating resists rust and corrosion, and salt-spray testing verifies it's ready for the elements.

Backed by Monroe's Limited Lifetime Warranty and Feel the Difference™ Guarantee.

Frequently Asked Questions

What vehicles does the Monroe 172243 fit?

It is a direct-fit replacement for the 2003 Subaru Baja and 2000-2004 Subaru Outback. Check the Buyer's Guide tab to confirm the fit for your specific vehicle.

Which position is this strut assembly for?

The 172243 is the front left (driver-side) Quick-Strut assembly. Struts are typically replaced in pairs, so consider replacing the opposite side for balanced ride and handling.

Do I need a spring compressor to install it?

No. The Quick-Strut arrives with the coil spring, upper strut mount, and strut preassembled as a single unit, so no spring compressor is required.

What's included in the assembly?

It comes as a fully assembled unit with the coil spring, premium upper strut mount, and strut, providing the components needed for the strut replacement in one part.

What are signs my strut assembly may need replacing?

Common signs include excessive body sway, increased vibration or road harshness, uneven ride height, or noise from the strut. Diagnose the cause before replacing.
