What It Is

21915-02 is the 18.3 mm, 30.8 mm, 230 mm version — Öhlins lists each size separately. Inner and outer diameter both matter; a bushing that is a little loose does more damage than none at all. A worn bushing lets the shaft move off centre, and the seal is the next thing to fail. Bushings take the side load so the seal only has to seal.

Why the Original

Every part in this catalogue is one Öhlins fits itself during assembly and service. Öhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. Öhlins parts are unit-specific: a close dimension is not a substitute. The Öhlins exploded view names the number for each position; we can look it up if you do not have it.

Identifying the Right Part

Order under 21915-02. Where several sizes share a description, only the number separates them. The published dimensions are inner diameter 18.3 mm, outer diameter 30.8 mm, length 230 mm — measure the old part against them if you are unsure. A bushing is a consumable and is replaced at rebuild rather than reused. Bushings carry the side load in a damper or fork and keep the moving parts concentric.

Fitting and Setup Service

Öhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.
