How to Use Our Dust Wiper Seal Press Tools

Proper installation of dust wipers is critical for keeping your fork smooth, leak-free, and reliable. These tools make it easy, but only if you install them correctly.

⚠️ Rubber mallet only.
Never strike this tool with metal. If the seal goes in crooked or too deep, removing it is annoying and can damage the seal. Take your time and try to get it right on the first install.
Pro Tip (Do Not Over-Strike)

Tap the driver gently with a rubber mallet. Never hit it hard like a hammer strike. Over-striking can crack the tool, and if the seal goes in too deep you will need to pry it back out.

Tool Options
  • Short Driver: compact and perfect for travel kits or small toolboxes
  • Long Driver: easier to align and tap smoothly, ideal for frequent use or tight-fitting seals
  • Ultimate Kit: includes all sizes (30 to 40 mm) plus a base plate for organization
Removing the Old Seal

A quick way to remove the old dust wiper is to pry it with a 24 mm wrench around the lower edge, then lever it out. Do not use anything sharp.

Step-by-Step Install
  1. Find the correct dust wiper seal for your fork using the S4 Dust Wiper Finder.
  2. Use our Dust Wiper Tool Calculator to select the correct press tool.
  3. Clean the dust wiper groove thoroughly with isopropyl alcohol.
  4. Place the pre-soaked foam rings at the bottom of the grooves. Make sure they sit flat and are not twisted.
  5. Remove the spring on the top (outside) of the wiper, then fully seat the wiper into the tool.
  6. Align the seal and driver squarely with the lower. Tap gently and evenly with a rubber mallet until the seal is flush with the flat surface of the lower leg. Never over-press.
After Installation (Grease It Up):
Apply a thin film of suspension grease (SRAM Butter, Slickoleum, etc.) on the seal inner lip and the stanchion bushing area. This improves small-bump sensitivity and reduces stiction.
Tips for Best Results
  • Go slow: crooked hits can damage the seal and increase stanchion wear over time
  • Center the tool carefully before tapping
  • Storage: heat-tested, but avoid long sun exposure (hot car storage is not ideal)
  • We left one outside in the sun for a month with no change, but still, be careful.
What Seals to Use

I personally like the green SKF seals. They seal very well and have low friction. The Fox factory dust wipers are also excellent and more affordable.

I have not tested the dual-compound SKF seals. They are supposed to last longer but can feel stiffer and more aggressive. Some riders report possible stanchion wear over time, so I never took the risk. They are also expensive for something many riders replace yearly.

How Often to Replace

Once per season is more than enough for most riders. On a lightly ridden bike, every two years can be fine. If you ride in mud or wet weather often, once a year is a safe baseline.

Do not wait for leaks. Many forks will not leak for a long time, but dirty or worn wipers can still accelerate stanchion coating wear.
