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

The cornerstone of Van Compass 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.
