กระบอกสูบ

Replacement was straightforward since these are genuine parts and the fit is exact. The threads align perfectly with the existing setup, so no fiddling or forcing needed. They've held up solidly through daily use for a few weeks now.

Swapped out my old worn cylinders on both sides and the fit was exact, no wobble or play once locked into the threading. Feels just as solid as the originals did when the system was brand new, which is all I wanted for a replacement part.

Took about ten minutes to swap both sides and they clicked into place exactly like the originals did. The fit is spot-on, so my device feels as solid as the day I first got it.
