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 if you install them correctly. Here's what you need to know.

⚠️ Only use a rubber mallet.
Never strike this tool with metal. If you misalign the seal or hit too hard, you can damage the fork or the wiper. If they go too deep, it's annoying to remove them again and it can damage them so try to get it in the first go.
Pro Tip:
Only tap the driver gently with a rubber mallet, never hit it hard with a hammer. Over-striking can crack the tool, and if the seal goes in too deep you will have to pry it back out again..

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, 40 mm) and a base plate to keep things organized

Removing the Old Seal

A quick way to pop out 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 Instructions

  1. Find the correct dust wiper seal for your fork on the S4 Dust Wiper Finder.
  2. Use our Dust Wiper Tool Calculator to determine which installation tool you need.
  3. Clean the dust wiper groove thoroughly with isopropyl alcohol.
  4. Place the pre-soaked foam rings at the bottom of the dust wipers grooves, ensuring they sit flush and are not twisted.
  5. Remove the spring on the top (to the outside of the fork) of the wiper and insert the dust wiper seal in the tool fully.
  6. Align the seal and driver tip squarely with the fork 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 and make sure it goes in really straight.
After Installation - Grease It Up
Coat the seal’s inner lip and the stanchion bushing area with a thin film of suspension grease (SRAM Butter, Slickoleum, etc.).
This drastically improves small-bump sensitivity and decreases stiction.

Tips for Best Results

  • Go slow : Misaligned hits can damage the seal and wear your stanchions over time
  • Center the tool carefully before striking
  • Store in your garage : While heat-tested for durability, extended sun exposure (like in a hot car) is not ideal
    • We left one outside in the sun for a month with no change, but still, be carefull

What Seals to Use?

I personally like using the green SKF seals, they seal really well and have very low friction. The Fox factory dust wipers are also excellent and a bit more affordable.

I’ve never tested the dual compound SKF seals, they are supposed to last longer but are stiffer and more aggressive. Some people have reported that they could cause stanchion wear over time, so I never took the risk. They are also pricey for something you replace every year.

How Often to Replace?

Once per season is more than enough for most riders. On my girlfriend’s bike (she doesn’t ride too hard), I replace them every two years with no issues. If you ride in mud or wet weather often, once a year is a safe baseline.

Don't wait until it starts leaking like in 2012, it will probably never leak but your stanchion coating will wear out.
