With input from IceAge Performance Backcountry Team, the new FOX lightweight mountain shocks improved ride quality is as significant as their weight savings. While it may seem like a stretch, this technology has trickled down from our trophy truck engineering successes. Simply put, we’ve freed the shock to move comfortably by using internal grooves to bypass oil around the piston in the ride zone while providing increased bottom-out resistance for those big hits by eliminating the grooves in the last 30% of travel. This provides the plushness to ride all day with the control you need for maximum fun. Our objective? Retain that great FOX ride feel while increasing bottom-out control, especially in coil-over shock applications.

Shocks Features

• Simple to use QS3 Compression and Rebound Adjustment

• Main air / Evol Air chambers for infinite tunability

• Lightweight bodies and caps

• Bypass technology for plush ride

• Premium Fox Factory / Chris Burandt calibration

• Preset / ready to ride right out of the box.

ADJUSTMENTS

• FLOAT air spring (ski / track front and rear)
• EVOL air chamber (ski / track rear)
• QS3 — Adjustable 3 position compression (ski / track front)
• QS3 — Adjustable 3 position rebound (ski / track rear)
• QS3 — Adjustable 3 position compression with lock-out mode (rear track only)

The combination of the main air spring and the evol air chamber results in an incredibly progressive feel. This means a plush compliant ride over the bumps and ruts while soaking up the biggest jumps and drops without bottoming. Couple this with the simple to adjust QS3 switch and you can go from powder carves to rough trail with the flip of a switch. No more fumbling with tiny iced up knobs and tiny adjustments you can't feel, the Quick Switch technology makes adjustment simple and clear. The positions represent real changes a rider can feel for easy to understand setting adjustments. Large background numbering makes it easy to see which position you are in. The QS3 tech is the perfect match for the mountain snowmobilers needs from novice to expert.

Baseline Range:

Soft: 45psi MAIN & 150psi EVOL
Stiff: 90psi Main & 250psi EVOL

The FOX Floats come with pressures of approximately 90 psi in the MAIN chamber and 100 psi in the EVOL chamber. These pressures may vary so its beneficial to check both chamber pressures beforehand to ensure consistency. Prior to adjusting the pressures in your FLOAT 3 shocks it's important to note that you must set the EVOL chamber before setting the MAIN chamber. The uniqueness of the FOX FLOATS compared to the alternative Coils is they provide supreme bottoming out resistance through the progressive dampening technology and have a multitude of "spring rates" thanks to using air in lieu of a coil. Collectively this provides the consumer with a shock that can be tailored to the specific riding style and conditions to achieve full benefit of the air suspension.

The range of shock pressures can be adjusted from 45 psi in the MAIN chamber & 150 psi in the EVOL to a stiffer calibration of 90 psi in the MAIN chamber & 250 psi in the EVOL. Between these ranges is personal preference according to riding style and conditions.

For the FOX FLOAT 3 EVOL QS3R we recommend setting the shocks to a middleground setting of 65 psi in the MAIN chamber and 200 psi in the EVOL chamber. This will provide the rider with a baseline of whether to increase or decrease the pressures accordingly. Thereafter, changing the shock pressures in increments of 10 psi for both chambers. For larger riders weighing more than 225+ (with gear) or for those who are jumping more frequently, more air pressure may be necessary.

Skid shock pressures can be used to achieve the following results. The front skid shock greatly controls ski pressure and weight transfer. Additional front track shock pressure will result in less ski pressure and more rapid weight transfer front to back when on and off the gas. The only side effect is this firmer shock is less compliant and will be more prone to trenching. Reduced FTS preload will result in more ski pressure and a sled with a more 'planted' feel capable of climbing on top of the snow better. The rear track shock adjustment greatly affects how the sled controls weight transfer. Increased RTS preload will create more ski pressure and help 'tame down' the sleds desire to wheelie.
