For standard ride height road cars, KYB offers the Gas-A-Just pressurized self-adjusting slimline shocks. These are the improved monotube shock design, with separate oil and high pressure gas chambers, so no oil foaming can occur in hard use, maintaining performance. Should be installed in axle sets, but are sold each. Ref: 552018, 552019, GSA388A, GSA389A.
Please note: these are not manually-adjustable shocks; all adjustments are internal and automatic.
