Product Details

KYB designed the Strut-Plus line for drivers who need a complete suspension strut and coil spring assembly that restores factory-style handling on the Nissan Altima. The SR4226 combines a KYB Excel-G strut with a precision-valved damping setup and a high-carbon steel spring to help return the vehicle to OE ride height and steering feel.
