Springs (set of 2)

These are a perfect match for the device—fit exactly as they should. The replacement tension is much more reliable than the worn-out originals.

The tension feels noticeably more consistent now that I’ve swapped in these replacement springs—assembly was straightforward and they sit snugly in place. Definitely worth grabbing if your originals have lost their bounce.

After swapping out the old ones, the assembly clicks back together cleanly and the tension holds steady through a full hour-long session. These are exactly the right size for the device and they don't squeak at all, which is a nice change.
