Available Online or order in store

SKU 854-02-000

The FOX Intelligent Quick Switch (iQS) system is a peerless suspension package tailored specifically for your mountain sled. FOX’s 1.5 ZERO coil-sprung shocks are known for their range of control and supple ride through the chop and crust.  

The electronically controlled suspension system allows you to adjust the performance of your sled in under a second. Depending on the conditions and terrain, tune your sled to provide you optimal control and comfort in any situation. Never take a break to adjust suspension again, thanks to iQS 

FOX iQS is an electronic modal damping control system. This system comprises a Bosch Electronic Control Unit (ECU), custom wiring harness, and electronically actuated valves integrated into each shock.  

The three-button switch mounted to your handlebar puts you in command of four unique shock modes. Each mode changes the character and balance of your sled by adjusting the compression damping of each shock. Ride primed to handle any situation in the snow.  

Are you scaling a near-vertical wall? Utilize lockout mode for better floatation and steering control. Lockout your rear track shock to prevent unwanted weight transfer to the rear to keep the sled planted when you twist the throttle. Worn out from a great day on the peaks and ready to motor back to the truck? Engage soft mode for a plush ride down the mountain. Between lockout and soft are settings to cover the full spectrum of riding from high-flying action to quick transitions boondocking through the trees.  

The FOX iQS system is a straightforward DIY install supported by a thorough step-by-step manual, online videos, and of course, our friendly FOX Service Center technicians.
