DW SM025 Complete Bass Drum Pedal Spring Assembly
The SM025 is the complete spring assembly offered by DW. It answers one specific case: when replacing the coil alone fixes nothing, because everything around it has aged along with it.
What sets it apart
- Complete spring assembly, not just the coil
- Original replacement part from the manufacturer
- Saves you a two-step rebuild
- The logical choice for a pedal with an unknown history
- Chrome finish
Coil alone or complete assembly: how to decide
The answer comes from looking at what moves. If the pedal returns straight, makes no noise and only the spring has sagged, the coil alone is enough. If the adjuster turns stiffly, if the hook has gone oval, if the rod shows visible wear, putting a new coil on that mount is like painting over rust.
The complete assembly takes the guesswork away: everything involved in the return is new on the same day, and the pedal starts again from a known state.
What a two-step rebuild really costs
The classic mistake is to order the smallest part, reassemble, find the same fault, then order the rest. In between, there is a rehearsal played on a so-so pedal and a second teardown to do.
On a used pedal, out of a rental fleet or a shared rehearsal room, nobody knows what was replaced or when. That is exactly the situation where the complete assembly is the shortest route.

Frequently asked questions
- How is this different from the spring sold on its own?
- The spring on its own is the coil and its felt. This item is listed as a complete assembly: it covers the spring mount, not just the elastic part.
- What exactly is in the box?
- The manufacturer lists this part as a complete assembly without detailing its contents. We would rather say so than list parts nobody has confirmed.
- Will it fit any DW pedal?
- It is listed for the brand's bass drum pedals, and their generations differ. Check the series marked on the baseplate before ordering.
- Do I need two for a double pedal?
- A double pedal has two springs. If both are the same age, it is best to do them together so both feet respond the same way.
