The Burandt Series, FLOAT 3 EVOL Quick Switch (QS) is the lightest mountain sled suspension package. These shocks are tuned specifically to suit Chris Burandt’s riding style. Ride harder in the backcountry with less fatigue without a compromise of durability. Experience a new sense of control on the snow due to less outboard weight.  

We designed the air-sprung mountain shocks with two primary objectives: weight reduction and ride performance. FOX optimizes the FLOAT 3 EVOL QS shocks through material reduction without a sacrifice of ride quality or structural integrity. We shaved weight from the reservoir walls and mounting hardware to save weight where it counts. The result is an air shock package in a league of its own.   

FOX’s position-sensitive damping technology, with origins in desert truck racing, is now applied to the Burandt Series coil-sprung shocks. Spiral grooves inside the shock allow the oil to flow around the main piston reducing damping force in the ride zone for a plush feel. The bypass grooves terminate through the final 30% of the travel, forcing oil to only flow through the main piston, and providing a significant increase of bottom-out resistance to cushion any hard hits. Our goal is to inspire confidence next time you send it big thanks to the extra support.  

FOX’s QS technology allows you to adjust the compression and rebound damping with ease to suit the snow conditions. Three positions keep the adjustment simple, so you focus on the ride instead of counting clicks. The FLOAT air spring and EVOL air chamber have an infinite range of spring adjustment. The air spring allows you to tailor the suspension specifically to your ride style or terrain. When the shock compresses through the travel, the spring force ramps up due to the progressive nature of air springs. If you ride aggressively and want a bottomless feel, the FLOAT 3 EVOL QS shock package is for you. 

Maximize the power-to-weight ratio of your sled by bolting on the new FOX Burandt Series shocks.

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.
