Suspension Fork Bushing Sizing Tool

10 reviews|5 answered questions


SKU: N/A Category:

If your forks feel harsh with poor small bump sensitivity the culprit could be tight bushings.  Our suspension bushing resizing tool can be used to resize your bushings to ensure optimum performance and better oil flow by allowing the lower leg lubricating oil to effectively coat the bushings and stanchions.  More information about the tool can be found in our blog post here.

This tool was designed and manufactured in our workshop in Aberdeen, UK and is currently in use in suspension workshops worldwide.  The sizes are laser engraved onto the heads for quick and easy identification.

Each kit will contain the handle and two precision machined burnishing heads sized at xx.07 and xx.10.  For example if you were to order a 36mm set you would receive one head sized at 36.07 mm and one at 36.10 mm.  All kits are supplied in a flight case with a custom CNC machined foam insert to keep them safe along with a detailed instruction guide.  We also offer a PRO version of the kit which has additional sizes as well as a larger case designed to store the handle fully assembled when not in use!

All our heads are precision machined in house to a ±10μm tolerance.  The tool is compatible with Fox and Rockshox forks as well as other manufacturers.  Just select the appropriate size tool from the drop down list.  If you would like custom sizes then please contact us here.

    Haven’t had chance to use it yet, it looks well made and comes in a nice box, but does seem overpriced for what it is.

    Excellent service. Haven’t tested the 36 mm heads yet but they look precision made.

    Very fast delivery time and great customer care. My kit was probably handled rough by the shipping company, all the kit was moved around inside the box when I received it. No damage on the parts though so no worries. The tools appear correctly made with consistent surface finish and good fit the the tool holder. I’d recommend this tool to anyone willing to spend a little extra to get their fork perfect. Pricing feels correct for the quality and quantity of tools.

      Thanks for the great review and I’m glad you love the tools! And thanks for noting about things moving around in the box. I put a lot of effort in to make custom inserts for the cases to keep everything in safely in place but going forwards I’ll tweak the inserts to provide a bit more squish against the lid to ensure they stay where they’re supposed to be even with the roughest of couriers!

Q & A

Hello, What material are the polishing heads made of? Are they abrasion-resistant? Can they corrode? P asked on January 2, 2024

Hi There,

Thanks for your question!

The exact material of the heads varies depending on what my suppliers have available when I order the raw materials but since 2021 they have always been a hardenable stainless steel so they have good wear properties and won't corrode under normal use.

Heads and kits made prior to 2021 used EN24 which offered good wear properties however they have the potential to suffer from flash rust if left in a damp environment (i.e. a cold garage or shed). Some of the individual heads I have in stock may still be EN24 but the kits are all new stock therefore are all stainless. Generally speaking as long as the heads are kept lightly oiled and in a dry environment then corrosion isn't an issue - it was mainly due to international orders where I had a few boxes get wet during transit.

The handles are made from 304 stainless which again won't corrode in normal workshop use.

hi, can you make a 32.03 & 32.07 mm combo heads only? I saw on youtube that these are the sizes to use for burnishing. Isn't 32.1 too big? or maybe your experience says otherwise, I'm curious about it, my new bushings are very tight and I'm not sure how to fix them... Florin asked on July 18, 2023


Thanks for getting in touch!

Yes, I can make custom sizes on request. The idea behind having multiple sizes is that you can push the first one through, check for stiction then go in with the next larger if required.

In my experience most forks benefit from at least the .07 mm going through. Some forks that are particularly tight need a smaller size to go through first to loosen them enough to get the larger tool going.

If you would like me to make you some custom sizes then drop me an email at [email protected] and we can discuss your options.

Does the complete kit come with 37mm heads? The picture shows it missing. jon asked on February 20, 2023


Yes, the full kit does - the picture was taken before I added it to the kit and I've not gotten around to adding photos so apologies about that!

Hello, does the complete kit come in the suitcase as in the picture? Can you make a better price for the workshop? Thanks Sergiu asked on September 2, 2022


Thanks for the question! Yes, the full kit comes in a flight case with a custom CNC machined foam insert for the heads as shown in the pictures. The sizing heads also have the sizes laser engraved on them for quick and easy identification/

As for pricing, we sell direct to the end user be it home shop or professional workshop therefore our pricing is the same regardless although quantity discounts may be available if you're after a few sets to kit out the workshop. Please get in touch at [email protected] to discuss further.
