What is a Gas-a-just monotube strut?
It's a high-pressure monotube gas strut offered as an OE replacement. It uses an air-free hydraulic piston/valve chamber plus a high-pressure nitrogen gas chamber with a floating piston for control and ride comfort.
Which vehicles does strut 551131 fit?

Why does the monotube separate the gas and oil?
Separating the high-pressure gas and oil supports fade-free operation and instant response, and the higher gas pressure responds quickly to help improve steering response.
Should I replace the strut mounts too?
To reduce the chance of noise and vibration, KYB recommends installing new strut mounts, part number SM5642, along with this strut.
What are signs this strut may need replacing?
Signs a strut may need replacing include fluid leaking, reduced control and handling, or increased noise and vibration. Diagnose the cause before replacing, as symptoms can have other sources.
