SKYRC Shock Oil Bubble Buster - RC Shock Vacuum Pump

Careful shock setup only works when the oil behaves like oil. Trapped air compresses, which can make damping feel vague and leave carefully built shocks behaving differently. The SKYRC Shock Oil Bubble Buster uses adjustable vacuum pressure to pull trapped air and micro-bubbles from oil-filled RC shocks, giving each rebuild a cleaner, more repeatable starting point.

Set the filled shock bodies in the built-in multi-size stand, tighten the vent screw, fit the clear cup, and turn the control knob. Turn it farther for faster vacuum, or back it down for thinner oil. Watch the bubbles rise, switch the unit off when they are gone, then open the vent before lifting the cup. Simple, manual, and blissfully free of another app.

The stand fits 13-19mm shock bodies, covering common 1/8 off-road, 1/10 touring, and crawler shocks. Use 5V USB-C at the workbench or a 5-15V XT60 source trackside. Maximum input current is 1A, and rated vacuum pressure is -36.05kPa +/- 2kPa.

It can also help foam tires absorb tire additive more evenly. Foam compounds vary, so test a small area first. The box contains the main unit and manual; shocks, oil, power source, and cable are not included.

Quick specs:

• Vacuum pressure: about -36 kPa (-36.05 kPa +/- 2 kPa)
• Pump power adjustment: 3-5.5V via rotary knob - higher for thick oils, lower for thin oils
• Shock body diameter: 13-19mm
• Capacity: a single shock or a batch on the multi-hole stand
• Power input: USB-C (5V) or XT60 DC input (5-15V), max 1A
• Internal battery: none - needs external power to run
• Controls: rotary power/speed knob plus a vent screw to release the vacuum
• Chamber: transparent cup over the shock stand, so you can watch the bubbles leave
• Dimensions: 98x88x185mm
• Operating range: 0C to 40C, 10-90 percent humidity, non-condensing
• Secondary use: helps traction additive penetrate deeper into foam tires; test a small area first
• In the box: vacuum unit (base, multi-size shock stand, clear cup), instruction manual
• Limitation: mild vacuum tuned for shock oil - not a shop degassing chamber for resin or silicone work
