Heads up: If you plan to rebuild a lot of shocks (10+), it's worth considering the official RockShox Vivid Service Toolset. It's not too expensive and built for shop volume. It doesn't include the IFP puller, the IFP Depth tool and the 1/2 shaft clamp that might be needed.

⚠️ RockShox Sealhead Torque Warning

RockShox recommends torquing their shock sealheads to ~30–34 Nm, but that’s arguably way too high.

Fox only uses 16 Nm on their sealheads and they work perfectly. Why? Because:

• The O-ring does all the sealing
• The fine threads generate massive force with very little rotation
• Overtorquing risks stripping threads, cracking parts, or ruining your tool

In this video at 13:50, even the pro doesn’t torque to 34 Nm, because you’d need over 50 pounds (22+ kg) of force on the wrench tip. That’s excessive.

We suggest staying around 20–25 Nm. That’s already more than Fox uses and more than enough to fully seal a fine-pitch thread with an O-ring.

Use our Torque Calculator to figure out the right pressure for your wrench length, there is a preset for the wrench.

Overtightening isn’t better. It’s just more likely to break something.

If you just want the factory wrench, you can also get the RockShox Vivid Spanner Wrench separately.

Here is a good Aftermarket Seal kit that you can get from MTB Hydraulics, it's really cheap and updated.

Equation:
Adjusted IFP Depth = Base IFP Depth − [(6.35² × Shaft Lost) / (Reservoir Diameter / 2)²]

Example:
Base IFP Depth = 33 mm
Shaft Stroke Lost due to negative spring = 10 mm
Piggy Back reservoir INNER Diameter (Measure it please) = 24 mm
Adjusted Depth ≈ 33 − [(6.35² × 10) / (12²)] = 30.25 mm

IMPORTANT: This equation is only valid if you're using a proper bleed fitting and syringe. If you're doing a hand bleed, do not adjust the IFP depth, just use the base value and use the Screwless Sealhead Negative Spring Compression Tool

WARNING: Shocks are pressurized systems. Always release both the air spring pressure and the IFP pressure before opening a damper. Failure to do so can result in injury or damage. This kit is designed for experienced home mechanics, if you're unsure, consult a professional. Read official RockShox service manuals and watch detailed rebuild videos before attempting service. You must open all adjusters during bleeding for it to work correctly. Rubber glove bleeding technique works very well on this shock.

Do not dismantle the eyelet or adjusters unless absolutely necessary.

Get yourself some Maxima Plush 7wt, Motorex 7.5wt, or RockShox 7wt suspension fluid for this shock.
