Special E-Type Series I or II competition rear shock with adjustable spring perch. XKs Unlimited is proud to be a National Distributor for SPAX Shocks for Jaguar in the U.S.A. We carry a full range of SPAX shocks for your Jaguar. Each unit is made to the highest standards of construction and is stout enough for competition use or general street application. The external screw adjustment provides for extra damping on rebound to compensate for wear or for the demands of competition. We have used and recommend SPAX shocks for street or track use. The external adjuster can be accessed while the shocks are on the car. There is no need to remove the shocks to adjust the dampening when compensating for wear or setting up for the demands of competition. We stock a complete selection of replacement Spax bushings, collets and other hardware. Call our sales staff for assistance. Our SPAX shocks are supplied with a durable powder-coated British Racing Green finish with a discreet XKs Unlimited logo applied. SPAX shocks are sold individually, and should be replaced in pairs, or axle sets.
