Skyjacker F840MKH-B 3-4 in. Suspension Lift Kit with Black MAX Shocks Mono-Beam

The Skyjacker F840MKH-B is a 3–4 inch suspension lift kit engineered for Mono-Beam front axle trucks, paired with Skyjacker's Black MAX shock absorbers for a complete, performance-ready suspension upgrade. Designed for power steering-equipped models, this kit delivers increased ride height and ground clearance while preserving a comfortable, controlled on- and off-road driving experience.

The included Black MAX shocks are twin-tube units built around advanced foam-cell technology. The foam-cell insert compresses to compensate for oil expansion under heat, maintaining consistent damping performance across the full operating temperature range. The foam-cell design also eliminates air inside the shock body, allowing flexible mounting orientation. Each shock features StableSteer valving to maximize tire contact with the road surface for a smoother, more stable ride.

Black MAX Shock Features:

• Foam-cell twin-tube design with increased fluid capacity for superior heat dissipation
• Chrome-plated shaft for durability and corrosion resistance
• 360-degree arc-welded end mounts with 180-degree directional mounting
• Sintered iron piston and orifice control disk for precise damping comfort
• Heavy-duty compression head and DOM tubing to reduce internal wear
• Durable black protective boot

Kit Includes:

• Front leaf springs
• Front and rear U-bolt kits
• Spring bushing kit
• Rear blocks
• Track bar bracket
• Black MAX shock absorbers
• All necessary mounting hardware and detailed installation instructions

Important Notes: This kit is designed for Mono-Beam front axle models only and is compatible with power steering-equipped vehicles only due to Pitman arm differences. Skyjacker backs this kit with a manufacturer limited lifetime warranty against defects in materials and workmanship.
