Bring your Sprinter into the 21st century with electronic damping adjustments, and adventure in comfort and confidence with a Van Compass Adapt suspension system. The Stage 4.5 system combines cutting edge shock control technologies with the proven and popular upgrades of the Stage 4.3 system. This is the ideal system for the uncompromising owner that wants to not only restore rear ride height and fix wallowing handling, but have the ultimate level of control to adapt to changing road and terrain conditions. This kit is perfect for built-out vans and RV's that do need rear sag correction and spend most of their time near or above GVWR.

System Benefits:

  • 4 corner in-cab electronic shock adjustment with Auto mode
  • Preserves factory CV, tie rod and control arm angles
  • Enhanced sway and cornering stability
  • Rear sag corrected by increase spring rate
  • Increase compliance and control over small bumps
  • Increased off road performance and capability

Falcon's 3.5 E-ADAPT Piggyback Reservoir Shocks represent the ultimate damping upgrade to your Sprinter's handling. These shocks feature a state of the art electronic control unit that can adjust the compression damping in real time while the vehicle is being driven, based on user set parameters for G-force and duration. Its multi-axis accelerometer monitors cornering, acceleration and braking forces to react and adapt to changing conditions. Each shock uses an electronic solenoid to control compression flow, and has an external fine-setting adjustment to control the range of firmness. The control unit, mounted under the driver's seat, uses a 3-position in-dash control switch as well as pairs with your phone to set user presets for the Auto mode parameters. The 3 position dash switch offers quick access to Soft, Firm and Auto mode for the shocks. As an added benefit, when the vehicle is turned off, the system even defaults the shocks to their firmest setting so that the van has maximum stability when parked, perfect for van life! A pre-cut and labeled harness with OEM grade wiring and connections ensures a reliable, trouble-free installation.

Our Stage 4.5 system retains the factory suspension geometry and 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, and the payoff is increased performance over any terrain while also improving handling for unexpected emergencies.

The Mini Leaf Spring pack offers a cost effective way to increase spring rate in the rear of your Sprinter, add approximately 1.25" of rear lift and restore lost ride height. Our mini spring is tuned to work perfectly with the OEM spring and represents an excellent solution to maintain factory wheel position and leaf spring geometry while restoring suspension up-travel on a heavy van. Included U-bolts ensure a quick and easy installation, and glide pads on the tips ensure quiet operation, just like your OEM springs.

Great results having these guys install a VanCompass 4.3 suspension upgrade on a Storyteller Overland Classic. They have done 50+ suspension upgrades and are knowledgeable and experienced. They keep a lot of components in stock, and offer many van upgrades besides suspension. Their pricing was also great, I drove 2+ hours to use their shop as they gave the best service and pricing when I was calling around.
