FOX INTRODUCES NEW iQS

— Push-button adjustable suspension —

By Tim “Lumpy” Tolleson

Make your appointments now for Shock Therapy at Camp RZR, because ST will be installing the all-new Fox iQS E-compression system on all two-year-old or newer UTVs with Fox Podium QS3, RC2 and IBP shocks. Fox’s iQS is a much simpler electronic compression-damping adjustment system than the Polaris Dynamix, as it doesn’t stiffen damping on the outside wheels in turns or front wheels when braking, and iQS isn’t interactive like Dynamix.

The iQS E-compression-damper assemblies simply screw into the shocks’ base valves in place of QS3, RC2 or IBP mechanical compression adjusters. Each kit has four iQS E-compression adjusters, a wiring loom and stand-alone shock ECU, and a three-way switch for the steering wheel, like the new Polaris RZR XP Pro Premium or Ultimate. Basically, the switch has Soft for rock crawling, Medium for desert whoops, and Hard for dunes and drifting. In effect, iQS is an electronic sway bar; leave it on Soft for general trail riding and even racing, then go to Medium for sand whoops or Hard for panic situations.

Fox Racing and Shock Therapy (ST) co-developed iQS, and ST has settings for all Maverick X3s and X3 Maxes. RZR and Talon settings are on the way. Better yet, the iQS system is stackable and growable as Fox introduces new systems. Owners will be able to tune iQS through Bluetooth and iPhone programs. ST has patented hydraulic sway bar links that act as E-bars, and owners can engage or disengage immediately.

Best yet, the price is going to be in the range of $1995 to $2070! Compare this to $22,999 for the new 2020 RZR XP Pro, $24,499 for the Premium or $28,499 for an RZR Pro Ultimate with Dynamix. With Fox iQS, buy the base model or upgrade your existing Fox-shocked UTV to this adjust-on-the-fly E-system for the cost of a set of tires and wheels.

With Honda introducing the Talon 1000X-4 and 1000X-4 Live Valve for 2020, owners of two-seat Talon 1000Xs and 1000Rs now have the opportunity to upgrade from QS3 shocks to the all-new iQS system without having to wait for Honda to introduce two-seat Live Valve editions. MSRPs haven’t been released for Talon X-4 models, but we’ll bet that the cost difference between the 1000X-4 and X-4 Live Valve is a heck of a lot more than $2000!

Honda developed its Live Valve control system in conjunction with Bosch, and it’s a variation of the Polaris Dynamix interactive system. Five inputs go into the Live Valve ECU—switch mode, engine/DCT ECU, IMU gyro, steering angle and brake-pressure sensors—which then adjusts each shock’s Live Valve every 5 milliseconds. This maximizes suspension performance, bottoming resistance, handling and ride comfort, and the driver can select between Sport and Normal settings. Honda claims its Live Valve is the smartest suspension system ever to grace a UTV.

Fox iQS doesn’t depend on several sensors like the Honda Live Valve or Polaris Dynamix, so it does only what you want it to do, only when you want it.

We’ll be featuring the Shock Therapy Talon 1000R in the January 2020 issue. ST has spring kits and valving for the Talon 1000X and 1000R, and torsion bars are on the way, along with rear-hub braces. So iQS is for Talons, but the biggest market will definitely be the myriad of Polaris RZR and Can-Am X3 owners who want to upgrade to the next-generation iQS on-the-fly adjustment system. Over-jump that dune? Hit the iQS panic button and save your equipment and spine!

Fox is set to unveil iQS at the Sand Sports Super Show, and Shock Therapy will also be on hand. Fox will likely install iQS only for Fox Factory drivers, leaving Shock Therapy to do consumer installs. ST has its big rig at Glamis all winter, or make an appointment for installation at ST headquarters: 23011 North 16th Avenue, Phoenix, AZ 85027; (623) 217-4959.
