Listed for: 2003-2009 Jaguar XJ8 (X350)Fitment notes & questions

If you want a lower, tighter 2003-2009 Jaguar XJ8 (X350) without a harsh ride, the SF Racing Sport Coilovers are made for that job: street use, adjustable height and 32 damping settings.

How this kit is set up for the 2003-2009 Jaguar XJ8

It is a true coilover at all four corners, so the spring and damper work as one unit front and rear. Damper bodies are 50mm front and rear. It comes with 16 kg/mm (about 896 lb/in) springs up front and 10 kg/mm (about 560 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. At the rear, the mounts are aluminum with rubber bushings.

Features

  • Monotube dampers, which shed heat well and hold their damping under hard use
  • 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
  • Ride height lowers roughly 1 to 2.5 inches below stock (SF Racing's figure) without giving up suspension travel
  • Independent lower mount adjustment keeps spring preload and damper travel where they should be when you change height
  • T6-6061 aluminum hardware (top mounts, perches and collars), anodized against corrosion
  • Zinc-plated shock bodies for rust protection
  • SAE9254 cold-wound springs
  • NOK seals and Italian IP damping oil

Who it suits

Best suited to daily drivers and weekend canyon cars where ride comfort still matters.

Before you order: Jaguar XJ8 fitment and setup

This SF Racing kit replaces the factory springs and shocks on the 2003-2009 Jaguar XJ8 with a height-adjustable coilover at each corner, so you set the ride height instead of living with a fixed drop.

Fitment notes

  • Listed for: 2003-2009 Jaguar XJ8 (X350).
  • Model years: 2003-2009. Check your car's year falls inside this range.
  • Chassis code X350: parts for other chassis codes of the same model usually won't fit.
  • Factory adaptive dampers: if your car has electronic or adaptive suspension, check whether the listing covers it or needs a cancellation kit.
  • Specs, lead time and warranty come from SF Racing and can change. The details above this guide are the latest we have.

Not sure it fits? Send us your year, make, model, trim and drivetrain and we'll check with the supplier before you order.

Ask about fitment

Plan the whole job

  • 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 Jaguar XJ8 coilovers

Will this fit my Jaguar XJ8?
It is listed for the 2003-2009 Jaguar XJ8 (X350). 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.
