Help restore factory ride height and reduce rear-end body sway with the Monroe Quick-Strut Suspension Strut and Coil Spring Assembly 173370. This rear complete strut and coil spring assembly is a direct-fit replacement for the 2006-2013 Lexus IS250 and 2006-2013 Lexus IS350, arriving fully preassembled so you skip the spring compressor entirely.

  • All-in-one repair: A single, fully assembled unit that includes everything needed for the strut replacement — no separate spring compressor required.
  • Ride height: The application-specific coil spring is calibrated to the OE design and engineered to restore ride height and support the vehicle's weight.
  • Maintains vehicle control: Reduces body sway, vibration and road harshness before it reaches the cabin, while the premium upper strut mount helps deliver smooth steering precision and guards against noise, vibration, harshness and memory steer.
  • Rust resistance: A protective coating resists rust and corrosion, backed by salt spray testing.

The preassembled upper strut mount, coil spring and strut carry an OE-style design and are fit checked and ride tested for the listed applications. Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.
