How to Lube and Tune Mechanical Keyboard Stabilizers

Stabilizers have you feeling like this? Let's fix that!

If your mechanical keyboard sounds rattly, inconsistent, or just plain noisy, there’s a good chance your stabilizers are the culprit.

Whether you’re building your first custom keyboard or refining your tenth, properly tuned stabilizers can make a massive difference in both sound and feel. A perfectly tuned stabilizer is truly the difference between a bad keyboard build and a great keyboard build. In this guide, I’ll walk you through everything you need to know. I will go over tools and techniques so you can get smooth, quiet, and satisfying stabilizers every time. 

What Are Stabilizers?

Stabilizers (or “stabs”) are used on larger keys like:

• Spacebar
• Enter
• Shift
• Backspace
  

They keep these keys level when pressed and prevent wobble. However, stock stabilizers often come with:

• Rattle
• Ticking
• Scratchiness

Tuning your stabilizers fixes all of that and it’s one of the highest-impact mods you can do.

There are several types of stabilizers, with PCB-mount and plate-mount being the most common. Since most boards use PCB-mount, this tutorial will focus on that type, but the steps for lubrication are the same for both.

What You’ll Need

Before getting started, make sure you have the right tools and materials:

Essential Tools:

• Lube Pen (or small brush if you have a jar of lube at home)
• Tweezers (or fingers if you're okay with getting your fingers a little messy)
• Keycap puller (if you're disassembling your board for tuning)
• Switch puller (if you're disassembling your board for tuning)
• Phillips head screwdriver (+)
• Stabilizer kit
• Krytox™ XHT-BDZ or other stabilizer wire lube
• Krytox™ 205g0 (or similar) for housings
  

Before You Start

Building a custom keyboard can come with a few unexpected challenges. If you ever get stuck along the way, you don’t have to figure it out alone.

You can always join the Omnitype Discord to ask questions, get real-time feedback, and learn from both our team and other experienced builders. It’s one of the best ways to improve quickly and avoid common mistakes.

Step 1: Familiarize yourself with the Stabilizer components

Each stabilizer consists of:

• Housings
• Stems
• Wires
• Screws (only for PCB mount stabs)
• Washers (not all brands include these)

Carefully separate each component. Keep everything organized so you don’t lose small parts.

Step 2: Lubricate the Stems

Using a small brush, apply a thin, even layer of Krytox™ 205g0 to stabilizer stems on all sides.

Tip: Apply a very thin and minimal coat to the inside of the stem where the wire will eventually rest. This will further reduce wire rattle in the long run.

Step 3: Lubricate the Housings

Using our lube brush, apply a thin, even layer of Krytox™ 205g0 to the inside walls of the stabilizer housings.

Tip: Less is more. Over-lubing can make your keys feel sluggish.

Step 4: Lube the Stabilizer Wires

This is where the magic happens for eliminating rattle.

Apply a generous coat of Krytox™ XHT-BDZ or your preferred wire lube to the ends of the wire where it enters the stem and where it clips into the stem. You'll lube in the shape of a capital "L".

Tip: Make sure it’s evenly coated, but not dripping. Over-lubing may make your keys feel sluggish. You should just barely see the wire through the lube. For Durock or Cherry clip-ins you may need a bit more lube. For TX AP and Knight you may need a touch less. 

Step 5: Assemble and Install

Put your stabilizers together and install them onto your PCB. 

Make sure:

• Wires are fully clipped in (the clip goes into the larger hole on the pcb)
• Stabilizers sit flush
• Secure tightly with screws
• Movement feels smooth before reinstalling switches

Step 6: Test Your Stabilizers

Before fully reassembling your keyboard:

• Install a switch in the pcb
• Add your keycap
• Press each stabilized key (try going from side to side)
• Listen for rattle or ticking
• Check for smooth travel

Step 7: Enjoy!

Congrats, now your next build will sound amazing! 

Something still sound off? Let's go over some other things you can try below.

Troubleshooting

• Warped spacebar: Sometimes during manufacturing the spacebar can get warped slightly. Place your spacebar on a flat surface and tap the sides. Does it rock? If so try a different spacebar.
• Unlubed switch: Sometimes a switch needing lube can cause issues too. The leaf tick or spring ping sounds can be amplified on stabilizer keys. Swap to a lubed switch or lube yours to eliminate those sounds.
• Check that the stabilizer is fully seated: If you didn't seat the stabilizer properly it can cause parts to collide in ways they weren't intended to.
• Add more lube: Maybe you went too light, you can "plug the butt" of the stab by gently lifting the stem and applying more lube in the hole where the wire rests. Most ticking and rattling is cause by the wire.
• Check for bent wires: Sometimes, very rarely, a wire can be slightly bent. This will cause it to be seated improperly or be hitting other components. You can place on a flat surface and gently bend the wire to straighten. Be very carefully, bending too hard can cause it to snap. Luckily this is a more rare occurrence and is likely the last resort. 

Common Mistakes to Avoid

• Over-lubing: Leads to mushy feel
• Uneven application: Causes inconsistent sound
• Skipping wire lube: Biggest source of rattle
• Rushing the process: Precision matters here
