Product Details

KYB Gas-a-just part number 7210003 uses a monotube adaptive damper design with two separate working chambers. The hydraulic piston and valve area provides responsiveness and control, while the high-pressure nitrogen gas chamber with a floating piston helps maintain a comfortable ride during normal driving and adds performance when needed. This design is intended to match the behavior of the original adaptive suspension on Lexus GS350 models.

This part cross-references Lexus 4852080291 and 4852080377 for the same application.

What This Strut Helps Address

• Excessive body motion over bumps and uneven pavement
• Reduced damping response from worn adaptive suspension components
• Ride fade caused by aeration in conventional hydraulic units
• Loss of steering precision and road control
• Suspension performance issues on Lexus GS350 front-left applications
