Fox Suspension Transfer SL Dropper Post Seal Kit

You should consider a service if you notice your post becoming sluggish, failing to return to full extension, or if you spot oil leaking from the seal head. These are clear indicators that the internal seals have worn out and are no longer maintaining proper pressure.

No, this specific kit is engineered exclusively for 2023 model year Transfer SL posts. It will not fit older versions of the Transfer or Transfer SL dropper posts, so please verify your model year before purchasing.

Yes, this kit is compatible with both 30.9mm and 31.6mm diameter Transfer SL posts. The seal components included are designed to accommodate these two common sizes.

If you have experience with basic suspension maintenance and the proper tools, you can certainly perform this service yourself. However, if you are uncomfortable working with pressurized systems, it is best to have a qualified mechanic handle the installation to ensure everything is seated correctly.

This kit is designed for the 2023 Transfer SL series, including FS (Factory Series), PSE (Performance Series Elite), and PS (Performance Series) models. Always double-check your post's specific model designation to ensure a perfect match.
