Skyjacker D400CDK-X 4-Inch Suspension Lift Kit with ADX 2.0 Remote Reservoir Shocks - Cummins Diesel

The Skyjacker D400CDK-X is a complete 4-inch suspension lift kit engineered specifically for Dodge/Ram trucks equipped with the Cummins Diesel engine. Designed and manufactured by Skyjacker Suspension — a trusted name in the off-road industry — this kit delivers a significant lift while maintaining ride quality, handling integrity, and long-term durability.

At the heart of this kit are the ADX 2.0 Remote Reservoir Shocks, which feature a remote reservoir canister that increases oil and nitrogen gas capacity for improved heat dissipation and fade resistance under heavy off-road use. The result is a consistent, controlled ride whether you're hauling, towing, or hitting the trail.

Key Features:

• 4-Inch Suspension Lift — provides increased ground clearance and allows fitment of larger off-road tires
• ADX 2.0 Remote Reservoir Shocks — high-performance remote reservoir design with enhanced oil capacity for reduced heat buildup and superior dampening
• Cummins Diesel Specific — engineered to account for the additional front-end weight of diesel-equipped trucks, ensuring proper geometry and ride balance
• Complete Kit — includes all hardware, brackets, and components needed for installation
• High-Strength Construction — components are built to Skyjacker's OEM-quality standards for long-lasting performance
• Maintains Factory Ride Quality — precision-engineered geometry corrections preserve alignment angles and driveline integrity after the lift

The Skyjacker D400CDK-X is ideal for Cummins diesel truck owners who demand more ground clearance and aggressive tire fitment without sacrificing everyday driveability or towing capability. This kit is a direct-fit, bolt-on solution designed to simplify the installation process for professional installers and experienced DIYers alike.
