Skyjacker D600CDKS6-M 6-Inch Suspension Lift Kit with M95 Monotube Performance Shocks

The Skyjacker D600CDKS6-M is a complete 6-inch suspension lift system engineered for 1989–1991 Dodge W250/W350 diesel trucks. This all-in-one kit replaces front and rear leaf springs with Skyjacker's proven Softride® units, delivering a significant lift alongside improved on- and off-road ride quality — without sacrificing the control and composure needed for daily driving or trail use.

The included Skyjacker Softride® leaf springs are individually shot-peened for maximum strength and durability. Tapered leaf ends distribute load more evenly and allow greater flex, while Teflon® wear pads between leaves and bolt-style spring clips eliminate inter-leaf friction and binding. The result is a suspension that rides smoother and lasts longer than conventional replacement springs.

Four M95 Monotube Performance Shocks are included to complete the system. These high-pressure nitrogen-charged, single-tube shocks feature a 46mm bore for superior damping capacity, a floating piston to prevent oil foaming, and 180-degree directional mounting for installation flexibility. A chrome piston rod resists corrosion, and the monotube design dissipates heat more efficiently than twin-tube shocks — meaning no fade or lag even under hard off-road use.
