Adjustable Dampers for your Jaguar

Spax have over 60 years experience developing upgraded dampers for Classic Jaguars
Providing tuned shock absorbers used by the worlds leading Jaguar Restorers & Race Prep Mechanics

From our origins Spax has had a tremendous affinity with Jaguar. XK-120 & XK-140 drivers were the first to benefit from adjustable Spax dampers which were immediately adopted to improve handling and roadholding.

When the E-Type was launched, almost from day one customers chose fit Spax as upgrades to OE and this tradition has continued right up to the present, further down this page we show a small selection of the thousands of Spax equipped Jaguars on the road today, many professional restorers utilise our dampers and there are plenty of examples of Concours vehicles shod with "G" shocks, starting with the ubiquitous G841 and, nowadays with our latest developed fixed and adjustable springseat designs.

It took 5 years for Jaguar Engineers to develop their first generation Jaguar IRS, which firmly established the marque's reputation for suspension sophistication, combining as it did smooth ride with excellent roadholding and low levels of noise, vibration, and harshness. Spax engineers immediately further improved the independently sprung wheels, which were damped by employing four coilover spring and damper units, attached to the crossbeam, by making adjustable damping performance units available in order that quick and easy race set-up could be achieved. The IRS design employed smaller springs to save space and Spax, with our exceptional stroke to closed length ratio, was ideally suited to squeeze the maximum performance from the new suspesnion architecture.

Our range includes catalogued items proven to upgrade suspension performance in a range of jags, from the XK-120 to the XJ12. Choose to fit our proven "swap-out" shock absorbers and discover the difference to handling and performance available

  • Spax "G" Dampers are Krypton Gas pressurised which minimises damper fade, allowing the shocks to be worked harder and stay responsive for far longer than OE
  • Tune your suspension using the 28 stages of damping response adjustment available with every Spax damper which allows drivers to individually set up their own suspension set-up
  • You'll be in good company using Spax, some of the world's most reknowned restorers employ our dampers and they're fitted to some of the world's most prestigious Classic Jaguars
  • Jaguar themselves have recently commenced a programme to manufacture 25 examples of their iconic Le Mans-winning D-types, the latest in their hand built Continuation series and we're proud to have worked with this famous marqure to supply authentic, high performance shock absorbers for these wonderful cars

  • Twyford Motors have documented a remarkable restoration of a beautiful XK-140. You can discover the whole story by clicking on the pictures above. Naturally, for the ultimate XK-140 makeover they chose Spax Dampers to ensure this car will handle every bit as good as it looks!


    There is a reason why so many Jaguars have Spax Yellow Dampers as part of their suspension and we're proud to acknowledge that it's because our shocks have been chosen by customers over more than 60 years as they seek the perfect set-up for their pride and joy. When buying Spax products you benefit from years of tried and trusted experience, proven designs that have been developed and improved upon year on year - which other damper manufacturer can offer more?

    Unlike some of our competitors we have our own factory, in Bicester, manufacturing to exacting TuV standards. We don't sub-contract our production from overseas and can offer industry leading one week production leadtimes. Quality inspectors monitor every stage of the production process. Spax dampers are manufactured to meticulous standards to produce winning performance straight from the box.


    Whether it's a damper designed specifically from our TrakSpax range, or supplied off the shelf from our catalogue, Spax dampers are all on-car adjustable to provide tuned suspension set-up. It doesn't matter if you use Spax on the road or the track, the quality, performance, roadholding and driver confidence will all be upgraded from original equipment. Drivers can tune handling and suspension response to the prevailing conditions and their driving style.

    Taking your car onto the track? For serious racing Spax have an unmatched pedigree, if you are looking to be sure footed and need to rely on the best set-up for your car then our Double Adjustable TrakSpax offer fantastic performance and excellent value for money, we'll ask for your Corner Weights and Spring Rates and then valve the dampers to provide a range of damping response to enable you to perfectly set up for track and driver.

    We know just how much of an improvement drivers notice once Spax Adjustables have been fitted, the car will drive, stop, corner & handle better than ever! The real pleasure is when customers let us know how happy they are with the demonstrable difference they've experienced, and we can point you in the direction of many documented examples of cars which have been restored and then improved, by the most meticulous mechanics, with the specification of Spax adjustables
