How to Use Our Open-Style Air Can Wrenches

⚠️ Critical safety warning +

Always fully depressurize the air can before using this tool.

If the shock is stuck down (air can pulled in and won’t extend), repressurize to at least 100 psi to equalize the chambers. Then release pressure slowly in 25 psi steps, letting the chambers equalize each time.

Opening a stuck-down shock without doing this can cause violent air can ejection. Treat air shocks as pressurized systems at all times.

Open-style wrenches use two swing-out handles that must be held closed during use. They are meant for air cans with external grooves or notches where closed wrenches do not fit or lack clearance.

How it works +
  • Seat the wrench teeth fully into the air can slots
  • Hold the secondary arms firmly closed while applying torque
  • Do not bend the secondary arms inward, they can break
  • Make sure all teeth are engaged to avoid point loading
  • Torque is spread across all teeth when aligned correctly
Important usage tips +
  • Do not bend the secondary arms inward, they can break
  • Always align the teeth with the piggyback or air can grooves
  • In most cases, the piggyback must sit between the two handles
  • Never torque without holding the arms closed
  • If the wrench flexes open, stop and realign
Recommended tools +
When to use an open-style wrench +
  • You have enough side clearance for the handles
  • The air can uses multiple robust grooves
  • You need flexibility around piggybacks or frame constraints
Disclaimer +

Open-style air can wrenches require correct hand placement and alignment. Always verify full engagement before applying torque. Improper use can damage the tool or the air can. By using this tool, you agree to our terms of service.
