KYB 349089 Shock Absorber - Rear

KYB Excel-G Rear Shock Absorber

The KYB Excel-G shock absorber, part number 349089, is built to restore original ride control, stability, and handling on select Infiniti rear suspension applications. It uses a nitrogen gas-charged, twin-tube design with OE-quality components and is assembled on KYB production lines used for original equipment manufacturing.

For drivers searching for a rear shock absorber for Infiniti G35, G37, G25, Q60, or Q40 applications, KYB Excel-G 349089 is calibrated to return the vehicle to its designed damping characteristics rather than change the ride feel.

Key Features

• Restores designed control, steering response, and body motion management
• Triple-lip fluid seal helps reduce oil and gas leakage
• Vehicle-specific, hand-assembled damping valves manage tire contact and suspension movement
• Supports proper operation of electronic safety systems by maintaining suspension behavior as engineered
• Heavy-duty strut body and bracket construction helps minimize flex and maintain alignment
• Internal anti-rollover spring is included in the design
