KYB 7210006 Suspension Strut - Rear

KYB Gas-a-just Rear Strut for Lexus

The KYB Gas-a-just 7210006 is a rear suspension strut built as a direct OE replacement for Lexus vehicles with adaptive dampers. It is calibrated to restore original handling and control while delivering immediate response when road conditions change.

For Lexus GS350, GS450h, GS460, and GS430 rear applications, this KYB Gas-a-just adaptive damper uses a monotube design with separate hydraulic and high-pressure gas chambers to maintain consistent damping and reduce fade from aeration.

Product Details

The KYB Gas-a-just line is designed for vehicles that use adaptive damping technology. Part number 7210006 combines an air-free hydraulic piston and valve area with a separate nitrogen gas chamber and floating piston, allowing the strut to deliver a comfortable ride in normal driving and firmer control when conditions call for it. This makes it a practical OE-style replacement for Lexus GS rear suspension service, including 2008-2011 Lexus GS350 rear with Adaptive Variable Suspension, 2007-2011 Lexus GS450h rear, 2008-2011 Lexus GS460 rear, and 2006-2007 Lexus GS430 rear.

Measured dimensions include a compressed length of 16.81 inches, an extended length of 21.93 inches, and a stroke length of 5.12 inches. Mounting details are E2 (14.2 x 60) lower and S1 (12 mm) upper. This part cross-references Lexus 48530-80451 for the same application.

Common Problems This Strut Can Address

• Excessive bounce or reduced damping control at the rear of the vehicle
• Loss of ride consistency caused by worn adaptive strut internals
• Handling changes from aeration-related fade in the damper
• Rear suspension noise or instability associated with worn OE struts
• Reduced response during braking, cornering, or uneven-road driving

Installation Notes

Verify rear fitment by model and year before installation. This part is intended for Lexus vehicles equipped with adaptive damping systems, and the mounting style should be matched to the original unit. Inspect related suspension components, alignment settings, and electronic suspension connections during service to ensure proper operation after replacement.
