Restore front-right ride height and controlled damping with the KYB Suspension Strut and Coil Spring Assembly SR4225, a complete corner unit that pairs a strut, upper mount and coil spring in one pre-assembled package. It installs as a direct-fit replacement for the front-right position on the 2007-2013 Nissan Altima — see the Buyer's Guide tab for engine-level applications. A strut assembly supports vehicle weight, sets ride height, serves as the steering pivot and helps control stability, so a worn unit is worth replacing when you notice bounce, nose-dive, uneven tire wear or poor handling.
- Complete corner unit: includes a KYB Excel-G strut, upper mount and application-engineered spring, pre-assembled for a straightforward install.
- Restored ride height: high carbon steel coil springs are developed around vehicle attributes and corner weights to help keep ride height within OE specifications.
- Precision damping: features a stronger steel outer shell and KYB's application-specific precision damping valves.
- Side-specific design: left and right part numbers with side-specific components, as the vehicle manufacturer intended; engineered to help vehicles with electronic safety systems (ESC, ABS, etc.).

What position is this strut assembly for?
This unit is for the front-right corner. KYB uses left and right part numbers with side-specific components, so order the correct side for your vehicle.
Will it restore my ride height?
