KYB SR4007 Strut-Plus Complete Corner Assembly - Strut, Mount & Coil Spring

The KYB SR4007 Strut-Plus Complete Corner Unit Assembly is a fully assembled, ready-to-install strut solution engineered to restore your vehicle's original ride, handling, and stability. As a trusted original equipment (OE) supplier, KYB designs this assembly to meet the same performance standards your vehicle had from the factory — no guesswork, no compromises.

The Strut-Plus combines three critical components into a single pre-assembled unit: an OE-restoring KYB strut, a precision-matched coil spring, and an upper mount. This eliminates the need for a spring compressor tool and significantly reduces installation time compared to replacing components individually.

Key Features:

• Complete corner assembly — includes strut, upper mount, and coil spring pre-assembled for direct bolt-on installation
• OE-quality KYB strut — engineered as an original equipment supplier for precise fit and restored damping performance
• High-carbon steel coil spring — developed using vehicle-specific corner weights and attributes to restore ride height within OE specifications
• Restores ride height — spring rates and geometry designed to return the vehicle to factory ride height tolerances
• Improves vehicle stability — helps restore handling dynamics, steering pivot accuracy, and compatibility with electronic stability and crash avoidance systems
• No spring compression required — pre-assembled unit eliminates the most dangerous and time-consuming step of strut replacement
• Direct OE replacement — designed for a precise, trouble-free fit on supported applications

The KYB SR4007 Strut-Plus is the ideal solution for technicians and DIYers looking for a safe, efficient, and reliable strut replacement. By addressing the strut, spring, and mount simultaneously, this assembly helps ensure all worn corner components are renewed at once — restoring the balanced, controlled ride your vehicle was designed to deliver.
