Skyjacker D400AK-X 4 In. Suspension Lift Kit with ADX 2.0 Remote Reservoir Shocks

The Skyjacker D400AK-X is a 4-inch suspension lift kit engineered for Dodge W250 and W350 trucks, pairing Skyjacker's proven Softride® leaf spring technology with the performance-grade ADX 2.0 Adventure Series Remote Reservoir Aluminum Monotube Shocks. This complete kit delivers increased ground clearance, improved wheel travel, and a more commanding stance without sacrificing on-road ride quality.

Softride® Leaf Spring Technology:

• Replacement front Softride® leaf springs are individually shot-peened with hard steel pellets at very high velocities to increase tensile strength
• Tapered leaf design distributes loads more evenly and creates greater flex at the leaf ends for improved articulation
• Teflon® wear pads between leaves and bolt-style spring clips prevent binding and eliminate friction
• Engineered processes maximize wheel travel, ride quality, and long-term spring life
• Includes front u-bolt kit and polyurethane spring eye bushings with replacement sleeves
• OEM rear leaf springs are retained; a high-quality add-a-leaf kit raises the rear to the proper lift height

ADX 2.0 Adventure Series Remote Reservoir Shocks:

• Aluminum monotube construction for superior heat dissipation and reduced weight
• Off-road race-inspired full-displaced valving system for unmatched front and rear dampening
• Application-specific valving and stroke tuned precisely for this lift height and platform
• External remote reservoir separates nitrogen gas from oil via an Internal Floating Piston (IFP)
• IFP technology prevents gas and oil from mixing or foaming (cavitation), ensuring consistent, lightning-fast shock response
• Engineered to perform at high-speed trail runs as well as slow-speed crawling

Kit Highlights:

• 4 inches of front and rear suspension lift
• Improved load handling, towing stability, and larger tire clearance
• Complete kit includes all necessary hardware for installation

The Skyjacker D400AK-X suspension lift kit delivers the perfect combination of on-road refinement and off-road readiness, making it an ideal upgrade for Dodge W-series truck owners seeking more capability and a dominant stance.
