XYZ Racing Super Sport Coilovers — Jaguar XJ (X351) 6 CYL (Fr FORK) (OE FOR REAR AIR STRUT) 2010-2019

The Jaguar XJ X351 left the factory riding on self-levelling air struts at the rear, a set-up designed to waft a long, aluminium-bodied saloon over broken tarmac rather than hold a line through a fast B-road or a track’s second-gear chicane. Those struts also get expensive once the bags start sagging and the compressor starts cycling more than it should.

XYZ Racing’s Super Sport coilover replaces that rear air strut with a conventional coil-and-damper assembly, matched to the correct fork-mount front strut for this 6-cylinder X351. It’s built for owners who want the 2010-2019 XJ sorted for fast-road driving and the occasional weekend track outing, not parked up waiting on an air suspension bill.

What this coilover does for your 2010-2019 Jaguar XJ

Swapping the rear air struts for coilovers gives you a fixed, adjustable ride height instead of a system that’s constantly compensating for load and, eventually, leaks. On a car this size and weight, body control under trail-braking and mid-corner load transfer matters more than most drivers expect, and the 36-way damping adjustment lets you firm up the rear specifically to manage that mass rather than accepting whatever the factory air system decided. Lower the ride height and you cut roll on the XJ’s long wheelbase; stiffen the damping and the rear stops wallowing when you’re carrying speed into a corner. It also means the car’s handling stops being at the mercy of ageing air-strut components.

About the Super Sport coilover

The Super Sport is XYZ Racing’s answer to the discomfort a stiffer set-up usually brings on rough British roads. Ride height is independently adjustable front and rear, and the damper offers 36 distinct settings so you can move between a comfortable daily setting and a firmer track-day mode without swapping parts. Construction is aimed squarely at cars that do both jobs: a run to work five days a week and a trackday or fast-road blast at the weekend, rather than a car built for one extreme or the other. For the X351 specifically, that means a rear end you can dial in once, rather than one that’s constantly self-adjusting around you.

Fitment for the Jaguar XJ (2010-2019)

This kit fits the Jaguar XJ X351, 6-cylinder variants built between 2010 and 2019, specifically where the rear used the factory air strut set-up. The front strut uses the fork-type lower mount fitted to this generation of XJ. Confirm your car matches the 6-cylinder, air-rear specification before ordering, as the X351 range was sold with more than one rear suspension type across this production run.
