Tuning stabilizers is the single biggest improvement you can make to a mechanical keyboard’s sound and feel. Untuned stabilizers rattle, tick, and create a mushy bottom-out that makes even expensive switches sound cheap. The process involves clipping, lubing, balancing the wire, and optionally adding internal padding to eliminate any remaining noise. It takes about 30 to 60 minutes for a full board, and the difference is immediately obvious.
Know Your Stabilizer Type First
Before you start, identify what you’re working with. Keyboards use one of three stabilizer mounting styles: plate-mount, PCB-mount clip-in, or PCB-mount screw-in. Plate-mount stabilizers snap into the metal or plastic plate above the PCB. PCB-mount stabilizers attach directly to the circuit board, either clipping in or screwing down.
If your keyboard has a universal plate (one that supports multiple key layouts), it almost certainly uses PCB-mount stabilizers because the plate cutouts are too wide for plate-mount clips. Fixed-layout plates often support both types. The distinction matters for tuning because PCB-mount stabilizers on a soldered board require desoldering every switch to remove. Plate-mount stabilizers only require desoldering the switches directly above them. If you’re building a new board, do all your stabilizer tuning before soldering anything.
Clip the Stabilizer Stems
Most Cherry-style stabilizer stems come with two small feet on the bottom. These feet are meant to soften the landing when you press a key, but in practice they make the bottom-out feel soft and inconsistent compared to your regular keys. Clipping those feet off with flush cutters gives stabilized keys the same crisp, clean bottom-out as every other key on the board.
Some manufacturers ship pre-clipped stems. Leopold, Vortex, and KBT boards typically come this way, and aftermarket stabilizers from brands like Zeal are designed without the extra feet altogether. If your stems have two small forked legs at the bottom, clip them flush. You want a flat surface so the stem lands cleanly.
Balance the Wire
The metal wire connecting both sides of a stabilizer is the most common source of ticking sounds. Even a slight bend causes one side to move before the other, producing an audible tick on every keystroke. Fixing this is tedious but essential.
Remove the wire from the housing and lay it on a flat, hard surface like a glass table or a mirror. Look for any spots where the wire lifts off the surface or bows to one side. Use flat-nose pliers to carefully straighten any bends. You’re aiming for the wire to sit completely flat with both ends making contact at the same time. Work slowly, because overbending in the other direction just creates a new problem. Once it looks flat, reinstall it and test for even movement on both sides. Wire balancing takes patience, but when the wire is truly straight, ticking is greatly reduced or eliminated entirely.
Lube the Right Parts With the Right Grease
Stabilizers have two types of contact: plastic sliding against plastic (the stem inside the housing) and metal sliding against plastic (the wire rotating inside the housing). Each benefits from a different viscosity of lubricant.
Stems and Housings
For the plastic-on-plastic surfaces, use a thin lubricant like Krytox 205g0. Apply a light, even coat to the inside walls of the housing where the stem slides, and to the stem itself. This reduces friction and eliminates any plasticky scratchiness. A thin layer is all you need here. Too much and the key will feel sluggish.
The Wire
The wire needs something thicker. You have a few good options: dielectric grease, Krytox 205g2, or XHT-BDZ. All three are viscous enough to stay in place on metal and dampen the wire’s movement inside the housing. Dielectric grease is the cheapest and easiest to find. XHT-BDZ is a popular choice in the custom keyboard community because it’s thick enough to coat the wire generously without migrating away over time.
Apply a healthy amount of your chosen grease to the wire, especially at the bend points where the wire clips into the stem housing. You can be fairly generous with wire lubrication without negative effects. The goal is to fill the gap between the wire and housing so there’s no room for the wire to rattle. If you’re using 205g0 on the wire (it works, just not ideally), you’ll need to apply it in multiple layers to build up enough thickness.
The Holee Mod for Remaining Rattle
If lubing and wire balancing don’t completely silence your stabilizers, the Holee mod adds a physical barrier inside the stem to lock the wire in place. The concept is simple: you place a small piece of material inside the hole where the wire sits in the stem, taking up the slack so the wire can’t move freely.
The original version used cut strips of fabric bandage, but PTFE (Teflon) tape works better. It’s thinner, more consistent, and doesn’t compress over time the way fabric does. Cut a small piece and press it into the inside of the stem’s wire channel, focusing on the top chamber where the wire sits. Press firmly with tweezers across the entire surface of the tape. If you don’t get good adhesion on the first pass, the tape will peel back up, so really work it into place.
You can also place a small foam pad or piece of bandage material on the PCB directly beneath where the stabilizer stem lands. This dampens the sound of the stem bottoming out against the board and adds a subtle cushion to the keystroke. Both mods together eliminate rattle and ticking almost completely.
Install Screw-In Stabilizers Safely
If you’re using screw-in stabilizers, place a non-conductive washer between the screw and the PCB before tightening. The metal screws can make contact with exposed traces on the circuit board and cause a short circuit. Some stabilizers ship with plastic or nylon screws that don’t carry this risk, but if yours are metal, use washers on every screw point. A small piece of electrical tape on the PCB under each screw works as a backup if you don’t have washers.
Dry-Test Before You Commit
Once your stabilizers are clipped, lubed, wire-balanced, and installed, don’t solder anything yet. Do a dry run by pressing switches into the plate without soldering them, then installing keycaps on the stabilized keys. Press each one repeatedly, listening for rattles, ticks, or creaks. Press off-center on the edges of longer keys like the spacebar, since that’s where stabilizer issues are most obvious.
If something sounds off, pull the switch, remove the stabilizer, and go back to the step that addresses the issue. Ticking usually means the wire still isn’t balanced. Rattling points to insufficient lube on the wire. A mushy or inconsistent bottom-out means the stems need clipping or the wire isn’t seated properly in the housing. It’s much easier to iterate now than after soldering 60 or more switches to the board.
For hotswap boards, you can test and adjust any time, which makes the process more forgiving. But even then, getting it right before full assembly saves you from repeatedly pulling keycaps and switches later.
