If your FOX FLOAT rear shock stays compressed or suddenly stops returning to its usual position, stop riding. Arrange a qualified bicycle or suspension-shop inspection; you do not need to prove a “stuck-down” fault before asking for help.
Do not try to force it back to length
Do not pull the shock apart, add pressure to force it out, bleed it down or open the air sleeve. A stuck-down air shock can retain trapped pressure; releasing air from the main chamber does not establish that it is safe to dismantle.
FOX’s 2021 FLOAT DPS and DPX2 owner information warns against opening or servicing a stuck-down shock and directs it to FOX or an authorized service center. This guide does not reproduce pressure tests. Older non-EVOL explanations are not a diagnosis for every FLOAT generation.
Give the shop a record, not another test
Describe what changed before you stopped: a sudden drop in ride height, recent service, an unusual noise or visible damage. Use existing photos. Do not ride or cycle the suspension again for a video.
Provide the bike make, model and year, plus the shock model and any safely visible serial number or identification code. Do not remove parts or manipulate the shock just to read a marking; let the shop identify it if necessary. A shortened shock is an observation, not confirmation of a particular seal failure.
Ask the shop to handle removal, shipment preparation, refitting and setup. Make sure the service request says the shock is suspected stuck down: a routine air-can maintenance booking alone does not establish acceptance of that problem.
Before sending it away, settle these three decisions
Can this particular shock be serviced?
FOX’s US intake instructions ask for photos and parts-availability confirmation for products older than 2016 or of unknown age. Confirm eligibility before shipping. An older unit is neither automatically accepted nor automatically beyond repair.
Are you comfortable with the spending authorization?
As checked November 2, 2026, FOX’s US intake authorizes the estimated service plus up to US$50 in additional parts and labor based on the technician’s evaluation. It says additional work beyond that allowance needs approval. This is not a promise to call before every extra charge.
Who handles the bike-side work and return?
Ask whether the shop’s quote includes removal, packing, refitting and setup, and what transport costs remain. Confirm any inspection or return charge if service is declined or parts are unavailable. Do not assume these are included in the factory-service estimate.
If you require approval of every additional charge, resolve that with the provider before submitting the shock; a note saying “quote first” does not itself change the published authorization. These are US factory-service terms, not a rule for every independent shop or country. Recheck the terms when booking.
FOX’s bicycle service page lists estimated shock-service pricing and notes that some models vary. Get the estimate for your actual shock rather than treating a routine service price as a confirmed stuck-down repair quote. If requesting warranty evaluation, provide the purchase information requested and wait for the result; the symptom alone does not establish coverage.
Compare the repair with a replacement approved for your frame
The useful alternative is not simply another shock marked FLOAT. Have the bicycle manufacturer or qualified shop confirm the replacement’s length, stroke, mounting hardware, clearance, tune and any required controls. Even matching dimensions are not the entire compatibility check.
Compare a confirmed service proposal, including the bike-side work and shipping, with an available compatible replacement fitted and set up. Service may preserve a shock already suited to the bike; unavailable parts, substantial damage or a costly uncertain repair may favor replacement. Do not buy a discounted but unconfirmed configuration to avoid waiting for the assessment.
For an inquiry, the bike and shock identification, existing photos and previous service findings are enough to start. You may ask Mad Labs about the situation, but an inquiry does not confirm acceptance or repair availability. Keep the bike out of use while the suspected stuck-down condition remains unresolved.
Based on the linked FOX information checked November 2, 2026, not a hands-on diagnosis or a claim that Mad Labs is a FOX service partner.
