SportCat™ Front and Rear
Sway Bar Suspension Upgrades
for the Jaguar XJS, XJ6 & XJ12

Jaguar XJS Front Anti Sway Bar Upgrade Kit
(also XJ6 & XJ12)

The XJS is a heavy car and was designed as a high speed Grand Touring machine. As a result, the handling can be less than what many drivers expect. Much of this can be attributed to the fact that the factory installed front sway bar is too small to adequately handle stress produced by a more than two ton car. Also, sadly, in 1981 Jaguar removed the rear sway bar from the XJS entirely. Jaguar finally saw the error in its ways in the 90's when it offered an optional Sportspack suspension upgrade that included the addition of a rear sway bar along with a larger front bar.

At V12 Performance we are proud to offer the SportCat sway bar upgrade kit(s) for XJS, XJ6 and XJ12 cars. This simple and relatively inexpensive suspension upgrade will dramatically improve the handling of your XJS and is one of the biggest bang for buck upgrades that are available for this car.

A driver that has installed this upgrade comments, "When I upgraded my OEM front roll bar and added a rear roll bar it completely changed the driving experience of my 86."

Another says "She drives like 'on a rail'. The steering is incredibly precise and the car stays absolutely flat on curves. (I'm having fun seeing how fast I can take interstate cloverleafs!)"

A third says, "I just finished installing a front and rear sway bar kit on my 86 Coupe. It is the BEST improvement I have made to my car! The car handles like a slot car!"

The front sway bar upgrade kit replaces the undersized 7/8" bar with a robust 1" diameter bar which increases torsional stiffness by over 50% and includes a black powder coat finish, quality high performance polyurethane bushings and all mounting hardware necessary for installation.

The same kit also fits 1970 - 1987 XJ6 and XJ12 and produces even more dranatic results since the XJ6 factory sway bar is only 3/4 inch diameter.

Jaguar XJS Rear Anti Sway Bar Upgrade Kit

The rear kit features a 7/8" black powder coat bar, polyurethane bushings, stainless steel mounting brackets and all necessary hardware. It utilizes the existing mounting points that Jaguar left on the car after they stopped installing the rear sway bar in 1981. Transform your XJS with the SportCat sway bar upgrade kit for either front, rear or both.

Front sway bar kit $267.50

Rear sway bar kit $369.50

Complete upgrade -Front and rear sway bar kits $599.00
