Wireless-connected ride dynamics for Fox's off-road racing trucks
Fully integrated wireless control for advanced off-road vehicle dynamics systems
Fox Factory’s challenge
Fox set out to build an intelligent, connected suspension control system for a limited-edition 2024 Chevrolet Silverado “super truck.” The solution needed to:
- integrate Fox’s Live Valve electro-hydraulic suspension
- run advanced vehicle dynamics algorithms in real time
- push and pull telemetry many times per second
- enable wireless configuration, updates, and mode control
- meet demanding reliability and performance requirements
- support a premium, unobtrusive driver experience
Fox had the core suspension technology — but bringing together embedded software, vehicle dynamics control, ECU development, and Bluetooth wireless communication required a strategic engineering partner with deep experience in performance-critical systems.
Having collaborated successfully with Virscient before, Fox once again tapped the team for embedded software, wireless engineering, system integration, and rapid prototyping.
Virscient’s deep engineering expertise was vital to integrating embedded wireless connectivity into Fox’s latest products.- Director, Advanced Development, Fox Factory
A connected suspension ecosystem — engineered for performance
Virscient worked closely with Fox to build a fully integrated suspension control platform, consisting of:
- a high-performance ECU
- Fox’s Live Valve system
- wireless mode controllers
- a mobile app
- a full real-time telemetry engine
Working as Fox’s strategic engineering partner, Virscient:
- led the system design around an STW Technic ECU – including Infineon TC1798 MCU
- built performance-critical embedded software to handle Live Valve control, telemetry and safety-critical behaviours
- integrated Nordic Semiconductor’s nRF52883 Bluetooth® multiprotocol SoCs into controllers and mobile interfaces
- rapidly delivered early prototypes of controllers, apps and subsystems
- optimised communication so riders could configure, update and monitor suspension performance right from their smartphone
The Outcome
The system launched on Fox Factory’s limited-edition 2025 Chevrolet Silverado super truck (pictured) – delivering an intelligent, connected suspension experience unlike anything on the market.
Drivers can now:
- configure suspension behaviour wirelessly from their smartphone
- update system modes and firmware without tools or shop visits
- access real-time performance telemetry streamed multiple times per second
- record and compare ride data to refine performance
- enjoy a seamless, premium experience where high-performance hardware and software disappear into the background
Fox achieved its goal of building a new benchmark for off-road ride dynamics, powered by a tightly integrated blend of mechanical engineering, vehicle dynamics, wireless connectivity and embedded intelligence.
As Virscient’s GM of Projects Owen Woollaston summarised:
“Fox came to us with an exciting vision to transform ride dynamics. The launch of the 2024 Silverado super truck shows exactly what we achieved together.”
