KYB 340099 Suspension Strut - Front Right

KYB Excel-G Front Right Strut for Infiniti

The KYB Excel-G suspension strut is built to restore original ride control, stability, braking response, lane-change behavior, and handling. This front right application for Infiniti EX and QX50 models uses KYB’s OE-style engineering to return the vehicle to its designed damping performance.

KYB Excel-G is a nitrogen gas-charged, twin-tube strut made on KYB OE assembly lines with OE-quality components. For Infiniti EX35, EX37, and QX50 front right service, part number 340099 is an OE-style replacement choice that focuses on restoring factory control rather than changing suspension character.

Product Details

Part number 340099 is engineered for the front right suspension position on Infiniti EX35, EX37, and QX50 models listed above. KYB’s Excel-G line is focused on restoring the vehicle’s original ride characteristics, making it a practical choice when the goal is to recover factory-like control after strut wear. This part cross-references Monroe Shocks & Struts 72700 for the same application.

The Excel-G line is built on KYB OE manufacturing processes and uses components selected to match original damping behavior. For Infiniti EX and QX50 service, that means more consistent body control, steering response, and suspension movement under everyday driving conditions. Part number 340099 is also identified by Infiniti OE references E61101BA0B and E61101BA0C.

Common Issues This Strut Can Address

• Excessive bouncing or poor rebound control
• Reduced steering response during lane changes
• Front-end instability over bumps and uneven pavement
• Suspension noise or vibration from worn strut components
• Loss of original ride height control and body motion management

Installation Notes

Install on the front right position only for the listed Infiniti applications. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. KYB recommends new strut mounts, part number SM5733, to reduce noise and vibration, and a KYB strut boot, part number SB103, to help protect the strut from dirt, debris, and salt.

Compressed length is 11.88 inches, extended length is 13.83 inches, and stroke length is 1.95 inches. Upper mount type is 12X1.25.

Quality Assurance

KYB is a major OE supplier, and the Excel-G line is produced on the same KYB assembly lines used for original equipment applications. The design uses OE-quality components and vehicle-specific damping calibration to help maintain the suspension performance expected by the manufacturer.
