Tame body motion and firm up ride control with the KYB Gas-a-just Suspension Shock Absorber (MPN 5530012), a high-pressure monotube gas shock built as an OE monotube replacement. It fits the rear left position on the 2019-2025 Nissan Altima, helping restore the vehicle's designed control and handling.
- Monotube gas design: Two separate working chambers — an air-free hydraulic piston and valve area for responsiveness and control, plus a high-pressure nitrogen gas area with a floating piston for a comfortable ride during normal driving and added performance on demand.
- Fade-free operation: The high-pressure monotube layout keeps the gas and oil separated for consistent damping and instant response.
- Triple chrome-plated piston rod: An ultra-smooth rod reduces seal wear; since fluid leaking can be a cause of shock failure, this helps guard against it.
- Quick steering response: The higher gas pressure reacts quickly to improve steering response, and helps keep Electronic Safety Systems performing as designed.
Sold individually. For even, balanced ride quality, replacing shocks as a matched pair is recommended best practice. If a worn or leaking original shock is the cause of your poor ride control, this Gas-a-just replaces it.

What position does this shock cover?
This is the rear left (rear) position shock absorber for the listed applications.
Is this a monotube or twin-tube shock?
It is a high-pressure monotube gas design that separates the gas and oil in two working chambers for fade-free operation and instant response.
Do I need to replace both rear shocks together?
It is sold individually. Replacing shocks as a matched pair is recommended best practice for even, balanced ride quality, though not strictly required.
What does the triple chrome-plated piston rod do?
The ultra-smooth triple chrome-plated rod is designed to reduce seal wear. Since fluid leaking can cause shock failure, this helps guard against it.
