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.”
