Overview
The Fox Racing Shox 985-24-103 is a Fox 2.0 Performance Series smooth body reservoir shock sold as a bolt-on unit. Its extended length is 24.95 in., its collapsed length is 15.35 in. and its stroke is 9.60 in. No vehicle is named for this part number, so fit must be verified before purchase.
The aluminum body is metal-impacted, which dissipates heat faster than conventional steel. An Internal Floating Piston keeps the shock oil separate from a high-pressure nitrogen gas chamber, supporting a predictable ride on rough roads.
Key features
- Metal-impacted aluminum shock body that Fox says sheds heat faster than steel
- Internal Floating Piston (IFP) separating shock oil from the gas chamber
- High-pressure nitrogen gas chamber
- Smooth body reservoir design
- Bolt-on installation
Before you install
A replacement shock controls how the suspension damps compression and rebound, so its length and stroke matter as much as its build. When a shock changes, the eyelets, bushings and travel limits all need to match the original geometry. Measuring first avoids a unit that binds at full compression or hangs loose at full extension.
Gas-charged designs carry internal pressure, and the floating piston keeps oil and nitrogen apart so damping stays consistent through repeated hard cycles. Before removing the old shock, look for oil seepage on the body, a bent eyelet, cracked bushings or worn rubber, since any of these can signal a unit near the end of its service life.
- Measure eye-to-eye length at ride height
- Note bushing sizes and any spacers
- Check mounts for cracks or corrosion
- Replace both sides of an axle together

Vehicle fitment
Direct Fit is the only fitment term for 985-24-103, and no vehicle years, models or trims are identified, so compatibility is unconfirmed.
Compare the lengths above with the shock being replaced. Check fit against your vehicle’s year, model and trim before ordering.
Installation notes
Measure the existing shock and compare its extended and collapsed lengths with 24.95 in. and 15.35 in. before installing. Nitrogen-charged shocks are pressurized, so handle the unit with care during removal.
What’s included
The package is the shock only, with no mounting hardware or accessories.
