It's the best seller for a reason. With everything needed to properly correct the handling problems heavy Sprinters can experience, our 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, we're able to minimize side to side sway and balance out jarring impacts using our deep knowledge of suspension tuning.

The cornerstone of our 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 Opti-Rate leaf spring pack offers flexibility for different van weights, restores lost ride height and corrects sag. Typically, 1.25" of rear lift is seen, resulting in a nicely leveled stance.

Our 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.
