Gas-a-Just Product Line

KYB Gas-a-Just shocks are monotube units intended for vehicles that see heavier use, including towing, added wheel and tire weight, or more demanding road conditions. The design uses an air-free hydraulic working area for control and a nitrogen gas chamber with a floating piston for quick response when suspension demand increases. For Acura ILX rear suspension service, 5530000 restores the original damping characteristics expected from an OE-style monotube shock.

What It Helps Address

• Excessive rear-end bounce or oscillation
• Reduced steering response caused by worn rear shocks
• Fluid leakage from aging shock seals
• Loss of ride control over bumps and uneven pavement
• Inconsistent suspension performance under heavier load or larger wheel and tire setups

Installation Notes and Tips

Fits 2022 Acura ILX, rear. Fits 2013-2021 Acura ILX, rear. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions when servicing the rear suspension on 2013-2021 Acura ILX models. Verify mount style and dimensions before installation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
