Product Details

KYB Excel-G struts are calibrated to return the suspension to its original operating characteristics rather than alter ride height or handling balance. For the Nissan Altima, this means more controlled braking, steadier cornering, and more predictable steering feel. The 3340242 strut uses a twin-tube, nitrogen gas-charged construction with OE-quality components and application-specific valving for the front left position.

This part cross-references Nissan E4303-6AM0A and E4303-6AM0B for the same application.

What It Helps Address

• Excessive bounce or float after bumps
• Reduced steering precision during lane changes
• Nose dive under braking
• Uneven tire contact from worn suspension damping
• Body roll and instability in turns

Installation Notes

Fits 2019-2025 Nissan Altima, front left. For 2019-2021 Nissan Altima applications, replace the suspension strut and coil spring assembly according to the manufacturer’s instructions.

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers, and the Excel-G line is built on the same OE assembly lines using OE-quality components. The design includes a triple-lip fluid seal, internal rebound spring, and a rigid strut body to support consistent suspension performance on the Nissan Altima.
