KYB Suspension Strut P/N:551132

Description

Restore the designed control and handling of your Lexus IS with the KYB Gas-a-just Suspension Strut (MPN 551132) — a rear, high-pressure monotube gas strut offered as the correct OE monotube replacement. This KYB strut drops in for the 2006-2013 Lexus IS250 and 2006-2013 Lexus IS350.

The Gas-a-just uses two separate working chambers: an air-free hydraulic piston and valve area for responsiveness and control, and a high-pressure nitrogen gas area with a floating piston that provides a comfortable ride during normal driving and adds performance on demand.

High-pressure monotube design: separates the gas and oil for fade-free operation and instant response.
Built for hard-working vehicles: designed for vehicles that work, tow, and run larger, heavier tires & wheels.
Triple-chrome-plated piston rod: an ultra-smooth rod helps reduce seal wear — fluid leaking can be a cause of shock failure.
Higher gas pressure: responds quickly to help improve steering response.

Because electronic safety systems depend on the suspension, brakes, and tires operating as the vehicle manufacturer intended, the Gas-a-just helps keep those Electronic Safety Systems performing as designed.

Frequently Asked Questions

What vehicles does the KYB 551132 strut fit?

It's a rear direct-fit replacement for the 2006-2013 Lexus IS250 and 2006-2013 Lexus IS350. Check the Buyer's Guide tab to confirm the fit for your vehicle.

What is the KYB Gas-a-just monotube design?

It's a high-pressure monotube that separates the gas and oil into two chambers — an air-free hydraulic piston/valve area and a nitrogen gas area with a floating piston — for fade-free operation and instant response.

What are signs a strut may need replacing?

Poor ride control, excessive bouncing, nose dive, uneven tire wear, or visible fluid leaking, which can be a cause of shock failure. Diagnose the cause before replacing.

Should I replace the rear struts in pairs?

Replacing the left and right rear struts together as a matched pair is recommended for even, balanced ride control, though it isn't strictly required.

Does the higher gas pressure improve steering?

The higher gas pressure of the Gas-a-just responds quickly to help improve steering response and adds performance on demand during driving.
