RockShox DebonAir Air Spring Sealhead

You likely need a replacement if your fork is losing air pressure over time, feels harsh, or exhibits oil leaking from the air spring side. If you are already performing a routine air spring service and notice wear on the existing seals, it is best practice to replace the entire head assembly to ensure a reliable seal.

No, this specific part is engineered exclusively for 32mm chassis models. It is compatible with SID RLC A1 (2017-2019), RL B1-B2 (2017-2019), and B4 (2020+) forks. Always verify your specific fork model and year before purchasing.

If you have experience with suspension service and the proper tools—such as a cassette tool or specific RockShox seal head tool, along with suspension grease—you can likely handle this installation. If you are uncomfortable working on pressurized air springs, it is safer to have a local bike shop perform the service.

Genuine RockShox components are manufactured to the exact tolerances required for your fork's internal air spring system. Using factory parts ensures the correct fit, maintains the intended air pressure consistency, and prevents potential damage to your fork's stanchions.
