Product Description

The King Shocks 25001-419A front coil-over is a high-performance suspension upgrade engineered for modern Toyota/Lexus SUVs - including 2024+ GX550, 2024+ Land Cruiser 250, and 2025-on 4Runner. Its 2.5" body with external reservoir significantly increases fluid capacity and improves heat dissipation, ensuring consistent damping and superior shock performance even under heavy off-road use, heavy loads, or extended driving. The extended-travel design enhances wheel articulation, helping maintain traction and ride quality on rough terrain, while the adjustable ride height and damping let you tailor the suspension to load, cargo, or terrain - from smooth highway driving to demanding trails.

Because this unit is bolt-on and uses factory mounting points, installation is straightforward without welding or frame modification. The premium 6061-T6 aluminum body, rebuildable internals, and serviceable design make 25001-419A a long-term, customizable upgrade for owners wanting greater control over ride characteristics, improved comfort and handling, or enhanced off-road capability - whether for daily driving, overlanding, or heavy-duty use.
