Detailed Description

The KYB Excel-G 339345 is a suspension strut for the front right side of the 2011-2013 Nissan Quest. It is designed to restore the vehicle’s original ride control and steering response using KYB’s OE-based construction and damping calibration. The twin-tube, nitrogen gas-charged design works with vehicle-specific valves to manage tire contact and body movement under everyday driving conditions.

This part cross-references Nissan E43021JA0B for the same application. The Excel-G line is a practical choice when replacing a worn front right strut on a Nissan Quest and when maintaining factory-style suspension behavior is the goal.

What It Helps Address

• Excessive bouncing or poor damping from a worn strut
• Reduced stability during braking and lane changes
• Loose or inconsistent steering response
• Uneven tire contact caused by suspension wear
• Noise or handling changes related to a failing front right strut

Installation Notes and Tips

Install 339345 on the front right position only for the listed Nissan Quest applications. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Inspect related suspension components, alignment settings, and the strut mount during service. KYB recommends protecting new struts from dirt, debris, and salt with KYB strut boot SB102.

Quality Assurance

KYB is a major OE supplier of shocks and struts, and Excel-G is produced on the same KYB OE assembly lines using OE-quality components. The design is calibrated to restore original performance characteristics for the Nissan Quest rather than change them.
