The FOX Float X refines All-Mountain and Enduro features into a smaller, lighter package at home equally on a flickable trail bike setup. The Float X offers rebound and compression controls as well as a 2 position, OPEN – FIRM, lever.
This is the 185 x 52.5mm FOX Factory Float X with 2 position switch, Trunnion mount
FOX Part Number: 979-01-054

FOX Float X
Click through these tabs to learn more about the Float X’s Compression, Rebound, Float EVOL and more.
Some of the details and improvements on the X lineup include:
High-flow main piston
Updated Air seal package
Volume spacers with smaller increments
MCU bottom out bumper
Numbered tool-free 12 position single-turn LSC (Low Speed Compression) adjuster
Independent firm mode circuit – Clockable 2 position adjuster
Increased rebound adjuster range (over DPX2)
Optimized reservoir lengths per shock size
Hydraulic top out feature
Reduced damper noise
Larger air sleeve bore reduces average rider pressure by 40 psi vs. DPX2
Bearing hardware compatible both sides
Air valve location offers improved frame fitment and pump access
Float X Compression Controls
The Float X rear shock provides riders Low-Speed compression as well as a 2 position OPEN – FIRM switch.
Low-Speed Compression is typically used with air spring and volume spacing to balance support. With increased Low-Speed Compression the shock will “stand taller” in the travel which helps bikes in fast corners or blasting through the chunk.
Float X Compression Adjustability:
Low-Speed Compression: 11 Clicks of Adjustment
FOX Float X 2 Position Switch
The Float X 2 position switch provides riders a “climb switch” shifting the shock from it’s OPEN circuit to a redesigned independent FIRM circuit.
With this redesign the Float X’s FIRM position is notably improved for the long climbs for those big descents.
FOX Float X Rebound Adjustability
Low-speed rebound – 16 clicks
Rebound is set to compensate for the air spring driving the shock back to neutral after compression. You can learn more about how Rebound, Air Volume, Compression and PSI interact on the Learn More tab
Float X EVOL Air Sleeve Details
(from FOX’s site)
Float X Max Pressure
FLOAT DPS EVOL and FLOAT X shocks have a maximum pressure of 350psi (24.1 bar)
FLOAT DPS Non-EVOL shocks have a maximum pressure of 300psi (20.7 bar)
Using the EVOL Air Sleeve
The EVOL air sleeve comes standard on FLOAT DPS and DPX2 models. The EVOL air sleeve provides an external negative air chamber integrated into the main air sleeve to significantly reduce the force to initiate travel, providing excellent small bump performance. The system is also more linear in its progression offering improved mid stroke support and better bottom out resistance. It is important to add or remove air from the EVOL sleeve as detailed below to experience the best possible performance.
When adding air to the air chamber, it is important to equalize the positive and negative air chambers by slowly compressing the shock through 25% of its travel 10-20 times after every 50psi addition.
Adding air to the shock without periodically equalizing the air chambers can lead to a condition in which the shock has more pressure in the positive chamber than the negative. In this condition the shock will be very stiff and can top-out. You can equalize the air chambers by slowly compressing the shock until you feel and hear a transfer of air. Hold the shock at this point for a few seconds to allow the air to transfer from the positive to the negative chamber.
When releasing air from the air chamber, it is important to do this slowly so the shock can transfer air from the negative to positive chamber and then be realeased through the Schrader valve.
Releasing the air pressure too quickly can induce a condition in which the negative chamber has more pressure than the positive chamber. In this condition the shock will compress into its travel and not fully extend. You can remedy this by adding air pressure until the shock extends, then slowly compressing the shock through 25% of its travel 10-20 times.

Float X: FOX Performance vs. Factory Kashima
There are a couple notable upgrades to the Factory X rear shocks compared to the FOX Performance or a OEM Performance Float X.
Float X Defining The Differences
FOX Factory shocks feature the Kashima coating as well as the top tier dampers. They’re called Factory or Kashima options. And they’re pretty easy to spot with the dark brown hue.
FOX Performance ELITE
FOX Performance Elite shocks typically feature the top tier damper systems, with all the adjustments of the Factory shock, but have a black ano coating.
Some shocks are available from FOX in a Performance configuration. The FOX Performance shocks tend to have a less sophisticated damper, generally without as many compression controls as the Factory or Performance Elite shocks are spec’d with. The damper body has a black ano coating.
OEM FOX Float X
You might see take-off shocks in a variety of configurations. Manufacturers can spec differences in the body, dampers, etc so understanding which damper is spec’d on an OEM shock will allow you to compare “apples to apples” so to speak.
FOX Factory Float X versus Performance Float X
This is the biggest difference. The FOX Factory Float X offers a 2 position OPEN – FIRM as well as the 11 clicks of low speed compression control. Performance offerings tend have a damper without the 11 clicks of low-speed compression control.
What this means is the Factory shock can use the low-speed compression with volume spacing to control support and bottom out. The Performance shocks lean on the volume spacing and PSI to produce support and bottom out characteristics.
This Low-Speed Compression feature is exceptionally notable as your ground speeds increase as well as for larger riders.
Kashima Coating vs Black Ano
Without access to all of FOX’s testing I’m referencing my years of experience riding both FOX coatings as well as our background on custom shock manufacturing and tuning.
The Black Ano coating works well. I ran a Performance Elite fork and shock with the black ano for years without noticing any wear in the coating.
The Kashima coating is slightly more “slippery” – which means less stiction – probably more notable for smaller riders.
When BikeCo has done custom internals or custom branded shocks we work closely with our coating specialists. Many of the additive packages aimed at producing a surface with less surface friction have an additional benefit that they work really well at negating or minimizing heat input on the shaft. This helps minimize performance changes to the shock during a fast run with thousands of shaft inputs. BTW: these additive packs tended to produce a rich, brown color… Just saying…
So in conclusion: Factory Shocks have notable advantages in overall tuning setup as well as direct benefits for large and small riders on different sides of the spectrum!
Comparing the Float X to other shocks
The Float X is designed to be competent from your all day trail adventure into mid level enduro runs.
Featuring more extensive compression control than the DPS the Float X is a popular upgrade to even smaller travel bikes.
The Float X is at home on bikes like the Mondraker RAZE, Yeti SB140 even onto a slightly more trail oriented Ripmo.
Riders looking for a shock with a little more “thump” will gravitate to the Float X2 if it fits the frame. The Float X will have a bit more “pop” than the X2 for riders looking for quick handling feel.
