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.

Canceled Orders

We want all customers to be happy with their purchases but in the event of a canceled order, we cannot recoup the fees charged to us by the credit card companies. When an order is placed, the credit card company takes a percentage of the sale, typically 5%-6% This is money that DOES NOT go to us and we do not get this charge given back to us when we refund an order. Therefore, if someone buys a suspension and then cancels, we pay the credit card company several hundreds of dollars that we cannot get back. Although you may not have noticed, it is industry standard for larger dollar items to have a "restocking fee" of 15% or more. We do our best to charge exactly what we get charged by the credit card company when you cancel an order. In the event of a canceled order, the 5%-6% that the credit card company charges us cannot be refunded. Please make note of this before you order. 

• All canceled orders over $1000 paid with a "Credit Card" will have a 5% credit card processing fee that cannot be returned.

• All canceled orders over $1000 paid with a "Shop Pay Installments" will have a 6% credit card processing fee that cannot be returned.
