Product Details

KYB Excel-G is KYB’s OEA-style replacement line, produced on the same OE assembly lines and using OE-quality components to return the suspension to original performance characteristics rather than changing them. Part number 3340187 is engineered for the front left position and is listed for 2016-2018 Nissan Altima, front left, and 2016-2020 Nissan Maxima, front left, plus 2021-2023 Nissan Maxima, front left. This part cross-references Nissan E43034RA1A and E43039HS0A for the same application.

What This Strut Helps Address

• Excessive bounce or poor damping over bumps
• Loose steering feel or delayed lane-change response
• Uneven tire contact caused by worn suspension control
• Noisy or unstable front suspension behavior
• Reduced braking stability from worn strut performance

Installation Notes and Tips

For 2016-2018 Nissan Altima and 2016-2020 Nissan Maxima applications, replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. KYB recommends new strut mounts, part numbers SM5838 and SM5821, to reduce noise and vibration. A KYB strut boot, part number SB102, can help protect the new strut from dirt, debris, and salt. Compressed length is 13.89 in., extended length is 19.81 in., and stroke length is 5.92 in.
