Skyjacker D400CK-X 4 In. Suspension Lift Kit with ADX 2.0 Remote Reservoir Shocks

The Skyjacker D400CK-X is a complete 4-inch suspension lift kit engineered specifically for 1974.5–1993 Dodge 1-Ton trucks (W250/W350). This kit pairs premium Skyjacker Softride® front leaf springs with the performance-driven ADX 2.0 Adventure Series Remote Reservoir Aluminum Monotube Shocks for a suspension upgrade that delivers both rugged off-road capability and improved on-road ride quality.

Skyjacker Softride® Leaf Spring Technology:

• Front leaf springs are individually shot-peened with hard steel pellets at high velocity to increase tensile strength and spring longevity
• Tapered leaf design distributes loads more evenly and promotes greater flex at the leaf ends for improved articulation
• Teflon® wear pads between leaves and bolt-style spring clips eliminate friction and prevent binding
• Polyurethane spring eye bushings with replacement sleeves included for a precise, rattle-free fit
• Includes front U-bolt kit for a complete front end installation

ADX 2.0 Adventure Series Remote Reservoir Shocks:

• Aluminum monotube construction provides superior heat dissipation and reduced unsprung weight
• Off-road race-inspired full-displaced valving system for unmatched damping performance
• External remote reservoir separates nitrogen gas from shock oil via an Internal Floating Piston (IFP), preventing cavitation and gas/oil mixing
• High-pressure nitrogen gas delivers rapid shock response to keep tires planted on all terrain types
• Specific valving and stroke tuned for this Dodge 1-Ton application
• Engineered for high-speed off-road use while retaining performance at low crawl speeds

Kit Highlights:

• 4 inches of front suspension lift height
• Rear block and U-bolt kit included for a leveled stance
• High-grade mounting hardware and all necessary bushings included
• Designed to maximize wheel travel while maintaining ride quality

The Skyjacker D400CK-X is the premium shock-equipped version of the D400 series, making it the ideal choice for Dodge W-Series 1-ton owners who demand serious off-road performance from a time-tested platform.
