KYB SR4546K Truck-Plus Complete Corner Assembly - Strut, Mount, Spring & Leveling Kit

The KYB SR4546K Truck-Plus Complete Corner Assembly is a fully engineered front suspension solution designed to raise the front of your truck while restoring factory-quality ride and handling performance. This all-in-one assembly includes a KYB strut, upper mount, coil spring, and leveling kit — everything needed to complete a front corner replacement in a single box.

Unlike generic, multi-vehicle strut assemblies, KYB engineers each Truck-Plus unit with corner-specific part numbers, meaning this assembly is purpose-built for a precise vehicle application rather than adapted to fit several. This matters because a front strut assembly is one of the most critical components on any vehicle — it bears the vehicle's weight, establishes ride height, serves as the steering pivot point, governs handling stability, and can directly influence the calibration of electronic safety systems such as stability control and collision avoidance.

What's Included:

• KYB performance strut (shock absorber)
• Upper strut mount and bearing plate
• Coil spring matched to vehicle specifications
• Front leveling lift component to raise front ride height
• All necessary hardware for installation

Key Features:

• Leveling Kit Integrated: Raises the front of the truck to level stance with the rear, accommodating larger tires and improving off-road ground clearance
• Corner-Specific Engineering: Designed and manufactured for a specific corner position — not a one-size-fits-all compromise
• Complete Assembly: Eliminates the need to source individual components separately; installs as a single unit
• OEM-Quality Standards: Built to KYB's stringent manufacturing tolerances to restore designed ride and handling characteristics
• Preserves Safety System Calibration: Engineered to maintain proper geometry so electronic crash avoidance and stability systems function as intended

The KYB SR4546K Truck-Plus is the ideal upgrade for truck owners seeking a reliable leveling solution without sacrificing ride quality or vehicle safety. KYB is a Tier 1 OEM supplier to major automakers worldwide, bringing the same engineering discipline to this direct-replacement assembly.
