KYB 7210001 Suspension Strut - Front Left

KYB Gas-a-just Front Left Strut for Lexus

The KYB Gas-a-just 7210001 is a monotube adaptive 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 quick response when road conditions change.

For Lexus GS350, GS450h, GS300, GS200t, RC350, and RC200t applications, this KYB Gas-a-just strut uses a two-chamber design with an air-free hydraulic working area and a high-pressure nitrogen gas chamber. That layout helps maintain consistent damping, reduce fade from aeration, and provide a controlled ride in normal driving with added firmness on demand.

Detailed Product Overview

KYB Gas-a-just line products are designed for drivers who want OE-style fitment with adaptive damping behavior. Part number 7210001 is a front left suspension strut with special lower mounting and an S1 12 mm upper mount. It measures 19.8 inches compressed, 23.29 inches extended, and 3.49 inches of stroke, supporting the suspension travel needed for the listed Lexus front-left applications. This part cross-references Lexus OE numbers 4852080285 and 4852080375 for the same application.

Compatible With 2013-2020 Lexus GS350, front left; 2013-2018 Lexus GS450h, front left; 2018-2019 Lexus GS300, front left; 2016-2017 Lexus GS200t, front left; 2015-2018 Lexus RC350, front left; 2017 Lexus RC200t, front left; and 2016 Lexus RC200t, front left. The KYB 7210001 is a practical replacement when the original adaptive strut has lost damping consistency or no longer responds correctly to road input.

Common Issues This Strut Can Address

• Excessive front-end bounce or reduced damping control
• Harsh or inconsistent ride quality from a worn adaptive strut
• Loss of response during braking, cornering, or lane changes
• Performance fade caused by aeration in the original damper
• Suspension noise or instability related to a failing front left strut

Installation Notes and Tips

Install according to the vehicle manufacturer’s instructions, especially on GS300, GS200t, RC350, and RC200t applications that require strut and coil spring assembly service procedures. Verify the front left position, upper mount type, and lower mount style before installation. Because this is an adaptive damper replacement, confirm the vehicle’s suspension configuration matches the listed Lexus applications before ordering.
