What It Is

Dimensionally this is 1 mm, 3 mm, which is how it is told apart from the rest of the range. Brackets and housings position the component precisely enough that it works as designed. Thread and length identify the adaptor; both are part of the installed length. Öhlins machines its housings from solid rather than casting them, which keeps the bores true.

Why the Original

This is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. Parts remain available years after a unit leaves the current price list, which is unusual in this trade. We can check the number against the Öhlins exploded view before you order — just ask. Tell us the damper's model designation and year and we will match the number for you.

How to Be Sure It Fits

Part number 21655-03 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. dimension a 1 mm, dimension b 3 mm is what distinguishes this number from its neighbours in the range. Öhlins uses adaptors rather than making a separate body for every chassis. Öhlins machines its housings from solid rather than casting them, which keeps the bores true.

Fitting and Setup Service

Fitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.
