13 mm Shaft Clamp
Designed for true 13 mm damper shafts. This is a rare size, only found on a very small number of boutique coil shocks. Not suitable for most air shocks or fork dampers.
Product photos may show a different clamp as reference. The actual 13 mm version may differ in appearance.
Technical Details & Compatibility
This clamp is designed to securely hold 13 mm damper shafts in a bench vise for disassembly and reassembly work.
- Confirmed fit: Formula MOD Coil shock
- Unknown: Other models may exist, confirmation required
- Not suitable: Most air shocks, fork dampers, and modern coil shocks
If you are unsure of your shaft size, measure it with calipers before clamping.
Setup & Usage
- Clean the shaft thoroughly with isopropyl alcohol until fully degreased
- No oil, grease, or residue on the shaft
- Wrap the shaft with a dry paper towel to improve grip and protect the surface
- Clamp with even bench-vise pressure; do not overtighten
- Apply heat before turning if threadlocker was used

Use the luggage scale torque calculator to estimate applied torque.
Sizing Confirmation
13 mm shafts are uncommon.
If the clamp does not seat easily or feels loose, stop immediately and re-check the shaft diameter.
Do not force the clamp onto a mismatched shaft.
Safety & Warnings
WARNING: Always fully depressurize both air and damper circuits before disassembly.
- Never clamp a pressurized damper shaft
- Oily or dirty shafts will slip and damage the clamp
- Using the wrong clamp size will damage both the shaft and the tool
- If it does not seat cleanly, stop and verify sizing
Slippage and damage almost always come from incorrect sizing or poor cleaning.
