The Stage 4.3 kit is for 4x4 Sprinter Vans weighing over 7,900 lbs and is for owners who feel like the rear of their van is riding low. This kit will bump up the rear ride height approximately 3/4" - 1-1/4" (19-31mm) depending on the weight of the van.
-To determine the actual weight of your vehicle, go to your local landfill to utilize their scale or use the CAT Scale Locator tool here to find a scale near you:
-If you have a Winnebago Revel and that has been accessorized with additional bumpers, gear or is frequently loaded heavily for long trips, then this is the kit for you!
-If you have a Storyteller Overland, then this is the kit for you!
-The Stage 4.3 kit utilizes front and rear fully adjustable piggy back SP2 3.3 Fast Adjust shocks for owners that want complete control over their suspension. The Fast Adjust shocks allow you to easily soften up the suspension for extended dirt road travel or firm it up for windy days and long highway stretches for sports car like handling.
-The Stage 4.3 kit includes the following components:
- Front Falcon 2.315" piggy back reservoir 3.3 Fast Adjust Shocks
- Front 4x4 Sprinter Sumo Springs
- Rear Falcon 2.315" piggy back reservoir SP2 3.3 Fast Adjust Shocks
- Dust boots for all 4 shocks.
- 3 leaf progressive rate mini-spring pack
- All necessary hardware and instructions for a simple installation
The Stage 4.3 Van Compass suspension package transforms the Mercedes Sprinter 4x4 from a violently swaying and lumbering cargo van into a vehicle with true German luxury car feeling and control both on and offroad. Vehicle control and suspension compliance are the two areas of ride quality we focused on when we engineered this kit. Each shock is tuned specifically for YOUR vehicle’s weight and intended purpose. Designed exclusively for 4x4 Sprinter vans running at a weight over 7900lbs to smooth out the harshness experienced on washboard roads and sharp, abrupt impacts. Additionally, this kit includes our tried and true 3 leaf mini spring pack to compliment the factory leaf pack to provide for an increase of about 3/4" - 1-1/4" of rear ride and simultaneously providing a 15% rear spring rate increase to help control the additional vehicle's weight. This spring pack eliminates that rear end sag on heavy vans and returns the vehicle to a more neutral, level ride height.
The Stage 4.3 kit does not change the vehicle's front ride height. It retains the factory suspension geometry which is critical for safe emergency lane change procedures as well as off-road performance. While other kits on the market force the van up 2” in ride height and sacrifice critical down travel in order to gain front spring rate, the Stage 4.3 kit utilizes a front sumo spring to accomplish the same thing without maxing out the limits of your van’s front suspension. This means control arm angles, axle shaft and steering angles stay neutral and your van retains it’s ability to articulate and keep it’s tires planted on the ground while traversing rough forest roads. The front sumo spring greatly helps with front stability and reducing harsh bottoming of the front suspension without sacrificing suspension travel. It optimizes your van’s front suspension and properly loads the chassis in an area designed to hold a spring load. Paired with a tuned Falcon piggy back 3.3 Fast Adjust front shock and the original Van Compass secondary shock mounting bracketry, your Sprinter will have a sporty but compliant feeling the way a Mercedes Benz vehicle should. Utilize the Fast Adjust knob to truly dial in the ride of your sprinter to your driving preference and the road conditions.
The last unique feature of the Stage 4.3 kit is the fully adjustable Falcon Piggyback Reservoir SP2 3.3 Fast Adjust Shocks. Just like the front shocks in this kit, these rear shocks have a MASSIVE range of compression adjustment at the simple flip of a knob. With the large red Fast Adjust knob, placed in an easy to access spot you will definitely take advantage of the adjustment features of these shocks. Flip the knob to position 1 (the softest setting) for dirt road travel. Set the knob to position 2 and utilize the micro dial to set the shocks for everyday comfort. This is your van’s every day normal running around town setting. Flip the knob to position 3 (the firmest setting) for when the van is loaded up with cargo and gear for a big trip. Cross wind sway, poor cornering stability, low speed rocking and harshness are a thing of the past with the Van Compass Stage 4.3 kit installed!
NOTE: The Falcon 3.3 SP2 Fast Adjust rear shocks are NOT compatible with Sumo Spring Rebel series of springs, specifically Sumo Spring part numbers: SSR-327-47-2 and SSR-327-40-2 There is a Sumo Spring bracket associated with those kits which makes contact with the large shock body of the Falcon shocks.
NOTE - Some 2019+ Vans with rear A/C are not compatible with our front shock mounts. Please look in the passenger wheel well for a/c lines under the plastic fender liner. Winnebago Revels do not have the a/c line run here.
Simple installation with basic hand tools.
