Restore front-left ride height and damping with the KYB Suspension Strut and Coil Spring Assembly SR4164, a complete corner unit that combines the strut, mount, and spring in one pre-assembled package. It drops in as a direct-fit, front-left replacement for the 2002-2006 Nissan Altima and 2004-2008 Nissan Maxima — see the Buyer's Guide tab for engine-level fitment. A strut assembly supports vehicle weight, sets ride height, serves as the steering pivot, and helps control stability, so a worn unit is worth addressing promptly.

Frequently Asked Questions
What vehicles does the KYB SR4164 fit?
It's a direct-fit front-left assembly for the 2002-2006 Nissan Altima and 2004-2008 Nissan Maxima. Check the Buyer's Guide tab to confirm engine-level fitment for your vehicle.
What comes in this assembly?
It's a complete corner unit — the KYB Excel-G strut, the mount, and an application-engineered high-carbon steel coil spring, all pre-assembled and ready to install.
Which corner does SR4164 cover?
This part number is the front-left (driver-side) unit. KYB uses side-specific part numbers and components, so order the matching part number for the opposite corner.
What is the spring made of?
It uses a high-carbon steel coil spring, matched to the strut and the vehicle's corner weights to help keep ride height within OE specifications.
Should I replace struts in pairs?
Replacing both sides of an axle together is a good practice for balanced ride and handling. This listing covers the front-left corner only; order the opposite side separately.
