KYB 5510026 Suspension Strut - Front Right

OE-Style Front Right Strut for Lexus

The KYB Gas-a-just 5510026 is a monotube suspension strut built as an OE-style replacement for select Lexus applications. It is engineered to restore original control, steering response, and ride consistency on the front right corner.

For drivers searching for a front right strut for 2013-2020 Lexus GS350, 2018-2019 Lexus GS300, or 2015-2018 Lexus RC350, this KYB Gas-a-just unit provides a direct-fit suspension service part for the listed vehicles.

Key Features

• Monotube OEM replacement strut designed to match the original suspension layout
• Restores handling and control on select Lexus GS and RC models
• High-pressure monotube construction separates gas and oil for consistent response
• Triple chrome-plated piston rod helps reduce seal wear and fluid leakage
• Higher gas pressure supports quicker steering response
• Supports proper operation of electronic safety systems that rely on suspension performance
• KYB recommends new strut mounts, part number SM5664, to reduce noise and vibration

Product Details

The KYB Gas-a-just line is KYB’s monotube performance replacement series, built with two working chambers: an air-free hydraulic section for damping control and a high-pressure nitrogen gas section with a floating piston. That design helps maintain fade-resistant operation and immediate response during normal driving and when suspension demand increases. KYB 5510026 is a practical choice for restoring front suspension behavior on Lexus GS350, GS300, GS200t, RC350, and RC200t models where the original strut has worn out.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Excessive front-end bounce or poor damping control
• Reduced steering response or vague handling
• Fluid leakage from a worn strut assembly
• Noise or vibration from aged suspension components
• Ride quality decline on the front right side of the vehicle
