Listed for: 1986-1993 Jaguar XJ6 (XJ40)Fitment notes & questions

For a 1986-1993 Jaguar XJ6 (XJ40) that sees track days as well as the commute, the SF Racing Track Coilovers add firmer valving on top of full height and damping adjustment.

1986-1993 Jaguar XJ6 setup details

Damper bodies are 46mm front and 50mm rear. It comes with 18 kg/mm (about 1008 lb/in) springs up front and 12 kg/mm (about 672 lb/in) at the rear. Damping is 1-way: a single knob with 32 settings changes rebound and compression together, which keeps tuning quick.

Highlights

  • Monotube dampers, which shed heat well and hold their damping under hard use
  • 32 damping settings on a single knob that sets rebound and compression together
  • 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 (20W)
  • Built-in dust boots and bump stops
  • Bolt-on install with no modifications, unless the notes below say otherwise

Before you order: Jaguar XJ6 fitment and setup

This SF Racing kit replaces the factory springs and shocks on the 1986-1993 Jaguar XJ6 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: 1986-1993 Jaguar XJ6 (XJ40).
  • Model years: 1986-1993. Check your car's year falls inside this range.
  • Chassis code XJ40: 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 XJ6 coilovers

Will this fit my Jaguar XJ6?
It is listed for the 1986-1993 Jaguar XJ6 (XJ40). 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.
