KYB Suspension Strut P/N:551129

Description

Restore factory ride control on the front-left corner with the KYB Gas-a-just High Pressure Monotube Gas Strut 551129 — the correct monotube OEM-style replacement, offered as an OE monotube replacement to help restore your vehicle's original capabilities. It installs at the front left of the 2006 Lexus GS300 and 2007-2011 Lexus GS350 (see the Buyer's Guide tab for engine details).

Two 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.
High-pressure monotube design: separates the gas and oil for fade-free operation and instant response, and the higher gas pressure responds quickly to help improve steering response.
Triple chrome plated chrome piston rod: ultra-smooth to reduce seal wear, since fluid leaking can be a cause of shock failure.
Built to work: Gas-a-just monotubes are designed for vehicles that work, tow, and run larger, heavier tires and wheels, and help keep Electronic Safety Systems performing as designed.

To reduce the chance of noise and vibration, KYB recommends installing new strut mounts, part number SM5738. This strut helps restore the designed control and handling of the Lexus GS.

Frequently Asked Questions

What vehicles does the KYB 551129 strut fit?

It is a front-left application for the 2006 Lexus GS300 and 2007-2011 Lexus GS350. Check the Buyer's Guide tab to confirm the exact fitment for your vehicle.

What position does this strut install in?

This is a front-left suspension strut. It replaces the original monotube unit on that corner of the listed Lexus GS applications.

What makes the Gas-a-just a monotube design?

It uses a high-pressure monotube layout that separates the gas and oil into two chambers for fade-free operation, responsiveness, and instant response during driving.

Should I replace the strut mount too?

To reduce the chance of noise and vibration, KYB recommends installing new strut mounts, part number SM5738, along with the strut.

What does the triple chrome plated piston rod do?

The ultra-smooth triple chrome plated chrome piston rod is designed to reduce seal wear. Since fluid leaking can be a cause of shock failure, this helps protect the seal.
