For standard ride height road cars, KYB offers the Gas-A-Just pressurized self-adjusting slimline shocks at a medium price point. 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.
These are not user-adjustable shocks. The adjustment is internal and automatic. For owner-adjustable shocks, see GAZ or KYB AGX product lines.
