Function
01115-21 is the 12 mm, 21 mm, 0.15 mm version — Öhlins lists each size separately. Changing one shim in a stack alters the damping curve measurably; that is why Öhlins sells them individually rather than only as sets. Shims are reused only if they are undamaged and flat; a coned shim is finished. Revalving means changing the stack, not the piston — that is why shims are sold singly.
Original Öhlins Part
Öhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. Rebuilding to specification only works if the parts are to specification — that starts here. Öhlins parts are unit-specific: a close dimension is not a substitute. Where a number has been superseded, Öhlins states the replacement — we pass that on.
Getting the Number Right
Öhlins identifies this position by the number 01115-21 in the exploded view for the unit it belongs to. Check inner diameter 12 mm, outer diameter 21 mm, thickness 0.15 mm against what you have removed; a close size is not the same part. Two shims of the same thickness but different diameter give completely different damping. Suspension technicians keep these in stock by size because a revalve means changing several at once.
Fitting and Setup Service
A damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.
