RockShox DebonAir+ Sealhead Assembly ZEB A2

You should consider replacing the sealhead assembly if you notice your fork is losing air pressure, feeling harsh, or if you see oil leaking from the air spring side. It is also standard practice to replace these seals during a full 200-hour service interval to maintain optimal performance.

No, this specific sealhead assembly is designed exclusively for ZEB A2+ models (2023 and newer). It will not fit earlier ZEB A1 versions, so please verify your fork's model year before purchasing.

If you are comfortable performing a standard air spring service and have the necessary RockShox tools—specifically the correct socket for the sealhead and a torque wrench—you can do this at home. If you lack the proper tools or experience with suspension internals, a professional mechanic is recommended to avoid damaging the stanchion or seals.

While the seals may have a light factory coating, you must apply fresh suspension grease, such as SRAM Dynamic Seal Grease, to the seals and O-rings during installation. Never install these components dry, as it will lead to premature wear and friction.

Yes, a failing sealhead assembly is a common cause of the 'suck down' phenomenon, where air pressure equalizes incorrectly between the positive and negative chambers. Replacing the sealhead and ensuring the transfer port is clear typically resolves this issue.
