Skyjacker D400CDKS4-B 4 in. Suspension Lift Kit with Black MAX Shocks and Front/Rear Leaf Springs

The Skyjacker D400CDKS4-B is a complete 4-inch suspension lift kit engineered for diesel-powered trucks, delivering a balanced combination of on-road comfort and off-road capability. This comprehensive kit replaces your factory front and rear leaf springs with Skyjacker's premium Softride® components and pairs them with Black MAX twin-tube shock absorbers for a fully upgraded suspension system.

Skyjacker Softride® Leaf Springs:

• Individually shot-peened with hard steel pellets at high velocity for maximum spring strength and longevity
• Tapered leaf design distributes loads more evenly and promotes additional flex at the leaf ends
• Teflon® wear pads between leaves and bolt-style spring clips eliminate binding and reduce friction
• Engineered specifically for diesel applications to achieve maximum wheel travel and ride quality

• Advanced foam-cell technology increases fluid capacity and compensates for oil expansion under heat
• Foam-cell insert compresses as the shock heats up, maintaining consistent performance throughout the operating temperature range
• Eliminates air inside the shock, allowing mounting in any direction
• Vehicle-specific multi-stage valving for a smooth, controlled ride on- and off-road
• Chrome-plated shaft for added durability and corrosion resistance
• 360° arc-welded end mounts with 180° directional mounting capability

Kit Contents:

• Front and rear Softride® leaf springs
