KYB 349075 Shock Absorber - Rear

KYB Excel-G Rear Shock Absorber

KYB Excel-G part number 349075 is a rear suspension shock absorber built to restore original ride control, stability, and handling response. It is an OE-style replacement for select Nissan applications, including Nissan Altima and Nissan Maxima rear fitments, with calibration focused on factory-like performance rather than changing the vehicle’s character.

Key Features

• OE-style replacement for Asian vehicles, including Nissan applications
• Nitrogen gas-charged, twin-tube design for consistent damping performance
• Triple-lip fluid seal helps reduce oil and gas leakage
• Vehicle-specific, hand-assembled damping valves manage tire contact, steering response, and body movement
• Internal rebound spring included
• Strong strut body and bracket construction helps minimize flex and maintain alignment
• Supports proper operation of electronic safety systems by helping suspension, brakes, and tires work as engineered

Product Details

The KYB Excel-G line is built on KYB OE assembly lines using OE-quality components and calibration methods. For drivers searching for a rear shock absorber for a 2007-2018 Nissan Altima or a 2009-2014 Nissan Maxima, KYB Excel-G 349075 is designed to restore the vehicle’s original ride control and handling balance. This part cross-references Monroe Shocks & Struts 5637 for the same application.

Part number 349075 is a practical choice when the goal is to return the suspension to factory-like response after wear, without altering the intended ride characteristics. It is especially relevant for rear shock replacement on Nissan Altima and Nissan Maxima models where original control, lane-change response, and braking stability matter.

Common Reasons to Replace

• Excessive bouncing or reduced damping at the rear suspension
• Loose or unstable handling during lane changes and cornering
• Uneven tire contact or reduced road control over bumps
• Oil seepage or gas loss from a worn shock absorber
• Restoring factory ride control after suspension wear
