Strut-Plus Product Line Details

KYB Strut-Plus assemblies combine an OE-restoring KYB strut with a matched coil spring and side-specific components. The SR4099 is part of KYB’s Strut-Plus line, which is built for vehicles that need a complete front suspension strut and coil spring assembly rather than a partial repair.

Detailed Description

KYB SR4099 is engineered for drivers replacing a worn front left suspension strut and coil spring assembly on the 2008-2012 Chevrolet Malibu, 2006-2010 Pontiac G6, and 2008-2009 Saturn Aura. KYB uses OE-based design targets for ride height, handling balance, and steering feel, then pairs the strut with a high-carbon steel spring to help return the vehicle to factory-style stance and control. This part cross-references Monroe Shocks & Struts (e.g., 172200) for the same application.

What It Helps Address

• Front-end sag or uneven ride height
• Clunking or noise from a worn strut assembly
• Excessive bounce, body roll, or reduced damping control
• Steering pull or inconsistent front suspension response
• Ride quality changes after strut and spring wear
