This genuine General Motors front suspension strut assembly (part number 13310728) is engineered for the left front driver side position. It features electronic real-time damping (RTD) technology with gas-charged twin-tube construction for precise ride control. The assembly includes the shock absorber, coil spring, and strut mount hardware. Designed as a direct OEM replacement for specific GM Epsilon II platform vehicles. The strut requires the companion upper strut mount kit (part number 11569637) for complete installation. Manufactured to GM OE specifications for durability, corrosion resistance, and consistent damping force across operating temperatures.
