Gaahleri Premium Series

Genuine replacement trigger spring for the Gaahleri Mobius Airbrush. OEM fit — matched to the Mobius's lever geometry and cutaway handle, preserving the full range of the built-in tension adjustment system.

Why You Might Need This

It's a small part with a big job. The trigger spring controls how the Mobius's trigger returns to neutral after each press — and it directly affects the "feel" and responsiveness of your airbrush. Over time, springs lose tension, deform, or break. A fresh spring brings the factory feel right back.

The Mobius is known for its ergonomic square lever and rear-adjustable trigger tension — a feature reviewers consistently praise. This OEM spring is engineered to work within that adjustment range, so you retain the full spectrum of light-to-firm trigger feel. A generic spring may not match the required tension, which can limit or override the adjustment system.

Signs Your Spring Needs Replacing

Spongy or loose trigger — doesn't snap back to neutral with the same firmness it used to.

Uneven resistance — the trigger catches or feels different at various points of travel.

Lost responsiveness — fine paint control is harder because the trigger doesn't return predictably.

Tension adjustment feels off — the rear dial doesn't seem to change the trigger feel the way it should.

What's in the Box

1× Gaahleri Replacement Trigger Spring for Mobius Airbrush.

Pro Tips

Work over a clean, light-coloured surface — the spring is small and will bounce if it escapes during disassembly. A white towel or a parts tray makes it much easier to spot.

Check before you swap — a sluggish trigger isn't always the spring. Clean the trigger mechanism and check for dried paint or debris first. If cleaning doesn't fix it, then the spring is your culprit.

Take a photo before disassembly — if this is your first time opening the back of your Mobius, a quick phone photo of how everything sits will save you guessing during reassembly.

Re-calibrate your tension after fitting — once the new spring is in, use the rear tension adjuster to dial in your preferred trigger feel before you start spraying.

Worth Knowing

Mobius only — this spring is specific to the Gaahleri Premium Series Mobius. It will not fit the Seeker, GHAD-39, GHAD-68, or any third-party airbrush.

Won't fix everything — if the trigger lever itself is bent, the needle guide is damaged, or the paint channel is clogged, a new spring won't solve those problems. Diagnose before you order.

Installation requires partial disassembly — you'll need to open the rear of the airbrush body to access the spring. It's not difficult, but small parts can escape if you're not careful. First-timers should watch a teardown video first.

Generic springs are cheaper — but they may not match the Mobius's required tension, which can limit the effectiveness of the rear tension adjustment system. The OEM spring preserves the full designed range.
