Key Features

• Monotube OEM replacement for the front right suspension position
• Separate gas and oil chambers for consistent damping and fade-resistant operation
• High-pressure nitrogen gas design for faster steering response
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Supports electronic safety systems by helping maintain factory suspension behavior
• Part number 5510011 for direct catalog identification

Product Details

KYB Gas-a-Just struts use a monotube layout with an air-free hydraulic working area and a separate high-pressure gas chamber. That design helps the strut react quickly to road inputs while maintaining controlled ride quality during normal driving. For Lexus IS applications, this front right strut is intended to restore the vehicle’s designed control and handling characteristics without changing the suspension layout.

Compatible With 2016-2018 Lexus IS300, front right; 2014-2018 Lexus IS350, front right; and 2014-2015 Lexus IS250, front right. This part number 5510011 is also a useful reference when comparing OE-style replacement options for Lexus IS front suspension service.

This part cross-references Lexus 4851080629 for the same application.

Common Issues It May Address

• Excessive front-end bounce or reduced damping control
• Loose or delayed steering response
• Ride fade during repeated suspension loading
• Oil leakage from a worn strut assembly
• Handling changes caused by heavier wheels, tires, or added vehicle load
