Which forks is the 38mm DH Stanchion Clamp compatible with?

The 38mm DH Stanchion Clamp is compatible with the RockShox BoXXer (2024 and newer) and the Öhlins DH38. It is designed specifically for 38mm stanchion tubes. If you are unsure of your fork's stanchion diameter, Shockwave Parts offers a Dust Wiper Seal Finder Tool to help identify the correct size.

Why do double crown forks require a stanchion clamp for service?

On double crown forks, the stanchions are not fixed through the crown once removed, so they spin freely. A stanchion clamp held in a bench vise provides the secure, non-rotating grip needed to open damper or compression assemblies, which are typically torqued tight. Without a proper clamping point, servicing these assemblies risks damaging the fork or injuring the mechanic.

How does the 38mm DH Stanchion Clamp protect the stanchion from damage?

The clamp is designed to wrap fully around the stanchion, providing 360° contact that distributes clamping force evenly and prevents surface scratching. Correct use requires thoroughly cleaning the stanchion with isopropyl alcohol, wrapping it in a clean paper towel, and spraying the clamp interior with isopropyl alcohol to maximize grip. Clamping on an edge or with any dirt present risks permanent scratching.

How does the 38mm DH Stanchion Clamp compare to universal strap-style stanchion holders?

Unlike universal strap-style or rubber-lined holders that rely on friction across variable contact areas, the 38mm DH Stanchion Clamp is machined to the exact 38mm diameter of the BoXXer 2024+ and Öhlins DH38 stanchions, delivering full 360° contact. This precision fit eliminates slippage under the high torque required to open damper assemblies, where a generic tool may rotate or mark the tube.

What is the price of the 38mm DH Stanchion Clamp and where can it be purchased?

The 38mm DH Stanchion Clamp is priced at CAD $30.49 and is currently in stock at Shockwave Parts. It is available directly at shockwaveparts.com. Shockwave Parts also offers 35mm and 40mm stanchion clamp variants for other fork sizes.

38mm Fork Stanchion Clamp Tool For BoXXer 2024+ & Öhlins DH38

Made specifically for 38 mm stanchions found on the new RockShox BoXXer (2024+) and Öhlins DH38. This clamp securely holds the stanchion tube in a bench vise for damper service without damaging the surface.

Available in two versions at the same price: straight or angled 35°. Both use the same 360° clamping surface and hold identically — the only difference is how the stanchion sits relative to your vise.

Which version should you pick?

Straight: best if you have a big wide vise where you can clamp off to the side and let the stanchion hang past the edge.

Angled: best if you have a small vise, or one with a wide bottom casting that gets in the way of long straight parts. The angle sends the stanchion off to the side so it clears the center of the vise instead of running into it.

Not sure? Look at your vise. If a 38 mm tube standing straight up in the jaws would hit the base or the bench, pick angled.

Why You Need This

Double crown forks don’t connect the stanchions through the crown, once removed, they spin freely.
A solid clamping point is required to open damper or compression assemblies, which are often torqued tight.
This clamp provides a secure, non-damaging grip when used correctly.
Stanchions are long. Whichever version you choose, the goal is the same: get the tube held solid without fighting your vise for room.

How to Use It Properly

Thoroughly clean the stanchion with isopropyl alcohol.
Wrap a clean sheet of paper towel around the shaft.
Spray 1–2 times inside the clamp with isopropyl alcohol, it dramatically increases grip.
Place the clamp fully around the stanchion. Never clamp on an edge; you need full 360° contact.
Clamp in your bench vise gently but firmly. If it slips, stop and redo your prep.
Angled version: set it in the jaws with the tilt running clear of the vise center before you close it, so you are not repositioning under load.

Critical Warning

Even one grain of dirt can permanently scratch your stanchion.
Always clean everything thoroughly and inspect the clamping zone before locking it down.
