KYB 3340244 Suspension Strut - Front Left

KYB Excel-G Front Left Strut for Altima

The KYB Excel-G suspension strut is built to restore original ride control, stability, braking response, and handling. This front left strut is a direct-fit replacement for select Nissan Altima models and is calibrated to return the vehicle to its designed suspension behavior.

KYB Excel-G, part number 3340244, is an OE-style replacement from KYB’s Excel-G line. It uses a nitrogen gas-charged twin-tube design and OE-quality components assembled on KYB production lines to match factory damping characteristics rather than alter them.

Product Details

The KYB Excel-G line is focused on returning the suspension to factory performance levels. For the Nissan Altima, part number 3340244 is engineered to support consistent ride control and steering feel while working with the vehicle’s suspension geometry and electronic safety systems as originally intended. This front left strut is a practical replacement when the original unit has lost damping performance, developed leakage, or no longer maintains stable handling.

This part cross-references Nissan E4303-6CC0A for the same application.

Common Problems This Strut Can Address

• Excessive bouncing after bumps
• Reduced steering response during lane changes
• Nose dive under braking
• Uneven tire contact caused by worn damping
• Fluid or gas leakage from the original strut
