SKY RC Shock Oil Bubble Buster

Once air bubbles are present, damping is compromised!

During oil filling or refilling, shaft cycling, or cap installation, air inevitably becomes trapped in the shock oil.
Air is compressible.
As a result, damping is no longer governed solely by oil, but repeatedly disturbed by trapped air bubbles.
This is not about feeling softer or stiffer — the damping logic itself is broken.

You think you’re tuning. In reality, you’re fighting variables.

If air bubbles remain in the shock oil, you may experience:

• Sluggish damping response, a vague feel
• Inconsistent performance between left and right shocks
• Identical setups producing different results
• Noticeable performance drift as temperature changes

At this point, swapping oil weights or springs only makes tuning feel more like guesswork.

The Correct Order:


Get the shock right first.
Without valid oil conditions, setup doesn’t make any sense.
Before tuning,
remove the variables.
Remove the air.
Leave only the oil.
Shock Oil Bubble Buster uses negative-pressure vacuum to force dissolved air out of the shock oil.
It doesn’t solve a feel problem.
It solves a physical state problem.
When oil is only oil,
damping is

Adjustable vacuum.
Matched to viscosity.
The Bubble Buster supports 3–5.5V wide-range voltage adjustment, providing the appropriate degassing strength for different shock oil viscosities:
• Higher voltage
For high-viscosity shock oils — fast, thorough degassing
• Lower voltage
For low-viscosity oils — gentle bubble removal without disturbing oil structure
It’s not about pulling harder —
it’s about being exactly right.

Accelerate Tire Additive Absorption
Psst…
a small pit trick!
When applying tire additive to foam tires, the Bubble Buster* creates a vacuum that removes air trapped inside the foam’s microscopic pores. When pressure returns, the additive penetrates deeper into the foam.
The result:
• Faster penetration
• More uniform absorption
• More consistent traction
Faster tire prep. More time to race.
*Use with discretion. Since foam tires vary widely in material and formulation, test on a small area first to verify compatibility.

Dual power input.
Flexible by design.
The tool adapts to your environment,
not the other way around.

• XT60 (5–15V)
Direct battery connection for trackside efficiency
• USB-C (5V)
Power bank or wall adapter for home maintenance

Multi-scale compatibility.
Versatile
Supplied with multi-size supports, the Bubble Buster is compatible with common RC shock types:
• 1/8 off-road
• 1/10 touring
• Crawlers
Single shocks or batch maintenance — the process remains consistent.
