KYB Excel-G Front Right Strut for Infiniti

The KYB Excel-G 340020 is a front right suspension strut built to restore original ride control, stability, and steering response. It is an OE-style replacement for select Infiniti applications, including Infiniti G35, G25, G37, and Q40 front right fitments.

Product Details

The KYB Excel-G brand line is focused on restoring factory ride characteristics for drivers who want original-equipment behavior from a replacement strut. For Infiniti applications, that means predictable front-end control, stable braking feel, and consistent handling during cornering and lane changes. The 340020 strut is a front right suspension strut with a compressed length of 16.73 in., extended length of 19.52 in., and stroke length of 2.79 in. It uses an E2(14X40) lower mount and a 12X1.25 upper mount.

This part cross-references Infiniti E6110JK01B and Monroe Shocks & Struts 71116 for the same application. The KYB Excel-G 340020 is a direct-fit option for 2007-2008 Infiniti G35, 2009-2010 Infiniti G37, 2011-2012 Infiniti G25, 2011-2013 Infiniti G37, and 2015 Infiniti Q40 front right positions.

Common Issues This Strut Can Address

• Excessive bouncing after bumps or dips
• Loose or delayed steering response
• Nose dive during braking
• Body roll during turns and lane changes
• Uneven tire contact caused by worn damping control

Installation Notes and Tips

Install the strut at the front right position only for the listed Infiniti applications. Follow the manufacturer’s instructions and replace the suspension strut and coil spring assembly as specified for the vehicle. Because this unit includes an internal rebound spring, the extended length may appear shorter than expected during handling. Verify mount type, dimensions, and vehicle configuration before installation, especially on 2009-2010 Infiniti G37 models that are listed without 4-wheel steering.

Quality Assurance

KYB is a major OE supplier, and the Excel-G line is built on the same assembly lines used for original equipment production with OE-quality components. The design is intended to restore factory performance characteristics for the Infiniti G35, G25, G37, and Q40 front right applications covered by this part number 340020.
