Features

• Diesel-specific D400CS front Softride leaf springs are shot-peened with hard steel pellets for increased tensile strength and maximum wheel travel without sacrificing spring life
• Tapered leaf design creates more flex at the leaf ends and distributes load more evenly, reducing interleaf wear and improving ride quality
• Teflon wear pads and bolt-style spring clips eliminate friction and binding throughout the front spring pack
• M95 Monotube shocks deliver 200 PSI gas-charged performance with an Internal Floating Piston (IFP) that separates nitrogen gas from oil, preventing foaming and maintaining consistent damping response
• DR40S rear Softride leaf springs replace worn OEM rear springs for a complete front-and-rear lift solution

Product Description

The Skyjacker D400CDKS4-M is a complete 4 in. Softride suspension lift system engineered for 1987-1991 Dodge W250 and W350 4WD trucks in both Gas and Cummins Diesel configurations. It replaces both front and rear leaf springs with Skyjacker's shot-peened Softride units - the D400CS front springs are specifically wound for the added weight of the Cummins engine, while the DR40S rear springs deliver a matched 4 inches of rear lift. The result is a fully leveled, lifted truck with improved suspension travel and reduced interleaf friction compared to worn OEM springs.

The D400CDKS4-M pairs these springs with M95 Monotube shocks at all four corners - a step up in damping performance over the Black MAX and Nitro variants. The M95's 200 PSI IFP monotube design prevents oil foaming under hard use, delivering faster and more consistent damping response on both the street and the trail. Installation is bolt-on with no cutting or welding required, and takes approximately 6 hours. A Pitman Arm (DA20), Adjustable Drag Link (DL10), and brake line extensions are required separately. Backed by Skyjacker's Limited Lifetime Warranty.
