Skyjacker D400BRK-X 4 In. Suspension Lift Kit with ADX 2.0 Remote Reservoir Shocks

The Skyjacker D400BRK-X is a complete 4-inch suspension lift kit engineered for classic Dodge Ramcharger and Trailduster 4WD trucks, pairing Skyjacker's proven Softride® leaf spring technology with the brand's flagship ADX 2.0 Adventure Series Remote Reservoir Aluminum Monotube Shocks for a dramatic upgrade in both lift height and damping performance.

At the heart of this kit are Skyjacker's Softride® front leaf springs, which are individually shot-peened with hard steel pellets at high velocities to maximize strength and fatigue resistance. The springs feature tapered leafs that distribute loads more evenly and promote greater flex at the leaf ends, while Teflon® wear pads between leafs and bolt-style spring clips eliminate friction and binding. Polyurethane spring eye bushings and replacement sleeves are included along with a front u-bolt kit for a complete front installation.

The rear lift is accomplished via a high-quality rear block and u-bolt kit, utilizing the OEM rear leaf springs to deliver a balanced, level stance front to rear.

ADX 2.0 Remote Reservoir Shock Features:

• Off-road race-inspired full-displaced valving system for superior front and rear dampening
• Aluminum monotube construction for improved heat dissipation and reduced weight
• External remote reservoir with Internal Floating Piston (IFP) separates nitrogen gas from oil, preventing foaming and cavitation
• Pressurized nitrogen gas delivers lightning-fast shock response to keep tires in contact with terrain
• Teflon banded piston for true, consistent shock reaction and added stability
• Specific valving and stroke tuned for this exact application
• Engineered for high-speed trail use while maintaining low-speed crawl capability

Kit Includes:

• Front Softride® lift leaf springs
