Few upgrades are as critical to a vehicle as a tuned suspension package. Adventure in comfort and confidence with a Van Compass system tuned for your van and needs. The Stage 4.3 Dually system pairs our innovative Opti-Rate Replacement Leaf spring with front and rear adjustable piggy back 3.3 Fast Adjust shocks and a front Sumo Spring bump stop upgrade. This system is intended for heavy weight vehicles like extended body adventure vans and Class B/C RV's that need a rear spring rate upgrade to counter build weight and correct rear sag that results in poor ride quality and wallowing handling. This kit can restore the ride height back to the original range, eliminates un-controlled swaying, and reduces harsh bottom out.
The Opti-Rate replacement leaf springs use a tunable preload system to change the spring rate that allows users to more closely dial in ride height and spring rate to their liking. Its clever design requires minimal tools to change rate once the springs are installed, and is designed to work on vehicles that spend their time at or well over GVWR.
Our Stage 4.3 Dually 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.
Falcon's 3.3 Fast Adjust Piggyback Reservoir Shocks represent the perfect pairing to our Opti-Rate Springs. Built specifically to our tune specifications, they represent the culmination of years of accumulated knowledge, applied directly to the adventure van market. These shocks have a MASSIVE range of compression adjustment at the simple flip of a knob. We've put the large red knob in an easy to reach location that allows for easy access and quick confirmation of the settings. The rear shocks also include the SP2 adjustment, which allows for further refinement specific to your preferences and vehicle's weight; with a simple turn of the shaft one of 2 tune profiles is engaged during installation. For more info on the functions of these shocks, you can read our 3.3 shock settings guide.
