It's the best seller for a reason. With everything needed to properly correct the handling problems heavy Sprinters can experience, the Van Compass 4.3 kit is the go-to choice for many owners. Whether you are looking for maximum stability in highway travel and treacherous wind conditions, or maximum compliance off pavement, this 4.3 System is able to minimize side to side sway and balance out jarring impacts using Van Compass's expertise in van suspension tuning.

The cornerstone of the Stage 4.3 kit is the 4-corner, adjustable Falcon 3.3 Fast Adjust Shocks with their huge range of compression adjustment available at the simple flip of a large, easily accessed Fast Adjust knob. This allows you to quickly adjust from the softest to firmest settings over a significantly larger range than the competition's smaller adjusters. A larger range of adjustment means the shocks are more effective and adaptable to multiple modes of use.

The rear mini leaf spring pack, tuned specifically to work with the stock rear leaf spring, restores lost ride height and corrects sag while retaining the quiet ride of the factory leaf spring. Typically, 1.25" of rear lift is seen, resulting in a nicely leveled stance.

Van Compass progressive foam Bump Buddy replacement jounce bumpers replace your hard factory rubber bump stops, adding improved spring curve progression, reducing sway, and increasing bottom out resistance without any unnecessary clunking or harshness.
