X3 Helix is the next step in our X-Series—built for people done with heat soak, sticky humidity, and “apps” that stop at Bluetooth range. An efficient PWM compressor modulates instead of hard cycling, so your 12V rooftop air conditioner holds target temperature with less battery stress. Helix adds scenes, schedules, and true remote access on phone, tablet, and watch—pre-cool before you return, keep pets safe while you’re out, and see live status anywhere.

  • Steady comfort: smooth modulation, less overshoot.
  • Real remote control: set and adjust from anywhere (not range-bound).
  • Cleaner interior: flush powder-coated metal faceplate (no bulky plastic box).
  • Humidity handled: High Humidity mode for van/RV cabins.
  • Built for miles: corrosion-resistant stainless hardware (our long-standing standard).
  • US-based support: Elkhart, Indiana—level-one techs and engineers.
  • Options: 12V Black or White.
  • Coach integration: RV-C ready via the optional Helix AC Controller for multiplex coach panels.

Bottom line: if you’ve outgrown on/off cycling and short-range apps, X3 Helix delivers steady comfort, real control, and road-ready construction.

The X3 Plus is the powerhouse variant in our Eco Level lineup—built on the rugged, reliable foundation of the Standard X3, but designed for adventurers who demand the ultimate cooling experience. While the Standard X3 delivers high-capacity off-grid performance, the X3 Plus takes it further with smarter control logic, climate-conscious refrigerant, and foam-insulated ducting for maximum efficiency.


A redesigned faceplate improves airflow, while features like high-humidity operation, mute mode, and stainless steel compressor support boost durability and functionality. Whether you choose the Standard or go for the Plus, you’re investing in one of the toughest and most capable off-grid air conditioners out there—built to handle any terrain and any adventure.

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 system pairs the Van Compass Mini Leaf Spring pack 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 built out adventure vans, loaded work/play vans and Class B 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.
Falcon's 3.3 Fast Adjust Piggyback Reservoir Shocks represent the perfect pairing to upgrade your Sprinter's handling. Built specifically to Van Compass 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. Van Compass 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.
The Van Compass Stage 4.3 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 off road. Vehicle control and suspension compliance are the two areas of ride quality we focused on when engineering 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. Van Compass’ 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.
