Listed for: 2004-2007 Scion xB (NCP31)Fitment notes & questions

Built for daily-driven cars, this SF Racing Sport kit replaces the factory struts and springs on the 2004-2007 Scion xB (NCP31) with height-adjustable coilovers and single-knob damping adjustment. This version is listed for FWD models.

What you get

Up front it is a true coilover; the rear keeps a divorced layout, with the spring and shock mounted separately like the factory setup. Damper bodies are 52mm front and 46mm rear. It comes with 7 kg/mm (about 392 lb/in) springs up front and 4 kg/mm (about 224 lb/in) at the rear. Damping is 1-way: a single knob with 32 settings changes rebound and compression together, which keeps tuning quick. The front top mounts are aluminum with rubber bushings, with aluminum camber plates (pillowball bushings) available as an option.

Key features

  • Monotube damper design for better heat control and fewer leaks
  • 32-level damping adjustment, rebound and compression combined on one adjuster
  • Built-in dust boots and bump stops
  • Bolt-on install with no modifications, unless the notes below say otherwise
  • Adjustable ride height, roughly 1 to 2.5 inches below factory per SF Racing, while keeping suspension travel
  • Separate lower-mount (length) adjustment, so height changes don't preload the spring
  • Anodized T6-6061 aluminum top mounts, spring perches and collars for corrosion resistance
  • Zinc-plated shock bodies for rust protection
  • SAE9254 cold-wound springs
  • NOK seals and Italian IP damping oil

Who it suits

Ideal for street cars that need a sensible drop and some tuning range, without going to track-level stiffness.

SF Racing coilovers for your Scion xB: what to know

This SF Racing kit replaces the factory springs and shocks on the 2004-2007 Scion xB with a height-adjustable coilover at each corner, so you set the ride height instead of living with a fixed drop.

  • Chassis code NCP31: you can usually find it in your vehicle documents or by decoding your VIN.

Parts that usually go with it

  • An alignment. Any change in ride height changes camber and toe. Set your final height first, then align.
  • Camber and toe adjustment. Bigger drops often need adjustable arms or camber plates to align properly. See alignment and camber kits.
  • Wheel and tire clearance. Check clearance at full lock and full compression, especially with wider wheels. Our ride height and wheel fitment calculator shows how much drop and offset change you are planning.
  • The right spring rate. Compare the rates listed here with what our spring rate calculator suggests for your car's weight and use.

Questions about Scion xB coilovers

Will this fit my Scion xB?
It is listed for the 2004-2007 Scion xB (NCP31). Check your year, model, drivetrain and chassis code against the product title. If anything is different, contact us and we will confirm fitment with the supplier before you order.
Do I need an alignment after installing coilovers?
Yes. Changing ride height changes camber and toe. Set your final height, let the suspension settle, then get the car aligned.
How low can I go?
It depends on the adjustment range the brand lists, your wheels and tires, and how you use the car. Most cars that are driven hard work best with a modest drop that leaves enough suspension travel.
Where do specs and warranty details come from?
From SF Racing. We sell parts from several brands and suppliers, and each one sets its own specs, lead times and warranty terms. The product details above are the latest we have.
