KYB 349139 Shock Absorber - Rear

KYB Excel-G Rear Shock for Nissan Maxima

KYB Excel-G shock absorber 349139 is built to restore original ride control, stability, braking response, and lane-change handling for select Nissan Maxima rear applications. It uses a nitrogen gas-charged, twin-tube design with OE-quality components and vehicle-specific damping calibration.

For 2009-2014 Nissan Maxima rear and 2016-2018 Nissan Maxima rear applications, this KYB Excel-G rear shock is an OE-style replacement choice that follows the vehicle’s original suspension tuning. Part number 349139 is also a direct reference point for buyers comparing replacement shocks by application.

Product Details

KYB Excel-G is the brand’s OE replacement line for drivers who want the suspension to perform as originally engineered rather than changing ride character. This rear shock absorber is made on KYB OE assembly lines and uses the same quality standards found in KYB original equipment products. On the Nissan Maxima, part number 349139 is designed to restore rear suspension control, helping the vehicle respond more predictably during braking, cornering, and lane changes.

This part cross-references Monroe Shocks & Struts 5659 for the same application. It is also associated with Nissan OE reference E62109N10C.

What It Helps Address

• Excessive rear bounce after bumps
• Loose or unsettled handling in the rear suspension
• Longer stopping feel caused by worn dampers
• Reduced steering and lane-change response from tired shocks
• Uneven tire contact from weakened suspension control

Installation Notes

Install on the rear position only. For 2016-2018 Nissan Maxima applications, replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify upper and lower mount types before installation, and confirm the vehicle is not equipped with the excluded Sport Package on 2009-2014 models. Because this unit includes an internal anti-rollover spring, the extended length may appear shorter than expected during handling.

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers, and Excel-G is built to OE standards using OE-quality components. The design focuses on restoring original suspension performance for the Nissan Maxima rather than altering it.
