KYB 5510014 Suspension Strut - Front Right

KYB Gas-a-Just Front Right Strut

The KYB Gas-a-Just 5510014 is a monotube suspension strut built as an OE-style replacement for the front right position. It is engineered to restore the original control and handling expected on the Lexus IS350 and Lexus IS250, while adding quick response for vehicles with higher load demands.

Key Features

• Monotube OE replacement design for direct suspension service
• Separate hydraulic and high-pressure gas chambers for responsive damping
• High-pressure nitrogen gas helps maintain fade-free operation
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Internal rebound spring included for controlled suspension movement
• Built for vehicles that tow, work, or use larger, heavier tires and wheels
• Supports proper operation of electronic safety systems by maintaining suspension control

Product Details

KYB Gas-a-Just part number 5510014 uses a monotube layout with an air-free hydraulic piston area and a separate gas chamber with a floating piston. That design improves steering response and helps the strut react quickly when the suspension is loaded. For Lexus IS350 and Lexus IS250 front right applications, this strut is a practical choice when the original unit has lost control, developed leakage, or no longer delivers consistent damping. This part cross-references Monroe Shocks & Struts (e.g., 39131) for the same application.

Compatible With 2014-2016 Lexus IS350, front right and 2014-2015 Lexus IS250, front right. The KYB 5510014 is also referenced by Lexus OE part number 4851080617.

Common Issues This Strut Can Address

• Excessive bouncing or poor rebound control
• Fluid leakage from a worn strut seal
• Loose steering feel or delayed response
• Reduced handling stability during braking and cornering
• Suspension fade under heavier wheel and tire setups

Installation Notes

Install according to the vehicle manufacturer’s instructions. Replace the suspension strut and coil spring assembly as directed for the application. Verify the front right position before installation and inspect related suspension components for wear. Confirm all mounting dimensions, including compressed length 17.43 in., extended length 20.78 in., and stroke length 3.35 in., before service.

Quality Assurance

KYB designs the Gas-a-Just line as an OE monotube replacement to help restore factory handling characteristics. The 5510014 uses a high-pressure monotube construction, an internal rebound spring, and a chrome piston rod to support consistent damping and reduced seal wear in daily driving and load-bearing conditions.
