This clamp is designed to securely grip oversized 5/8″ damper shafts in a bench vise.

• Fits: Original FOX DHX RC4 (circa 2012)
• Use cases: Eyelet removal, main piston removal, rebound assembly service
• Not compatible: FOX DHX2, RockShox, Cane Creek, or any modern shocks

If your shock is newer than ~2013, this is almost certainly the wrong clamp.

• Clean the shaft thoroughly with isopropyl alcohol (multiple passes)
• No oil, grease, or residue on the shaft
• Wrap the shaft with a dry paper towel to increase grip and reduce marking
• Clamp with even bench-vise pressure; do not overtighten
• Apply heat before turning if threadlocker was used

For torque estimation on old hardware, use the luggage scale torque calculator.

True 5/8″ shafts are rare.

If you are working on an older shock and are unsure, measure the shaft with calipers before clamping.

This clamp will not fit anything smaller.

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 re-check shaft diameter

Old hardware is brittle. Excess force will snap parts before threads move.
