Skyjacker D400BAK-X 4 In. Suspension Lift Kit with ADX 2.0 Remote Reservoir Shocks

The Skyjacker D400BAK-X is a complete 4-inch suspension lift kit engineered for classic Dodge full-size W-series pickup trucks (1974.5–1993 gas models). This kit combines Skyjacker's proven Softride® front leaf springs and rear add-a-leaf packs with the premium ADX 2.0 Adventure Series Remote Reservoir Aluminum Monotube Shocks for a significant upgrade in both ride quality and off-road performance.

Kit Includes:

• Front Skyjacker Softride® replacement leaf springs
• Leaf spring bushings and bushing sleeves
• Front U-bolt kit
• Polyurethane spring eye bushings with replacement sleeves
• Rear add-a-leaf pack
• ADX 2.0 Adventure Series Remote Reservoir Aluminum Monotube Shocks (front and rear)

Softride® Leaf Spring Technology:

• Springs are individually shot-peened with hard steel pellets for maximum strength and durability
• Tapered leaf design distributes loads more evenly and increases flex at the leaf ends
• Teflon® wear pads between leaves and bolt-style spring clips prevent binding and eliminate friction
• Engineered for maximum wheel travel, ride quality, and long service life

ADX 2.0 Remote Reservoir Shock Technology:

• Race-inspired full-displaced valving system for off-road performance at any speed
• 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) for consistent damping
• Specific valving and stroke calibrated for this application
• Performs from high-speed trail runs down to slow rock crawling

Important Notes: This kit does not fit models equipped with a diesel engine. Models from 1975–1977 require Skyjacker Steering Arm Part #DA60 (sold separately).

Backed by Skyjacker's limited lifetime warranty, the D400BAK-X delivers the ground clearance needed for larger tires while maintaining the on-road refinement and off-road readiness Skyjacker is known for.
