Offset Bushings | Trek DRCV / RE:aktiv Shock Conversion Kit – Offset Bushings | Shock Mounting Hardware

Looking to upgrade from your stock shock on a Trek frame? You'll need our bushing conversion kit! This has been one of our most popular Offset Bushing kits over the years so we've decided to offer it as a stand alone product.

Trek commonly use unique shock sizes such as 197mm which aren't commonly available for aftermarket shocks. Our conversion kit reduces the new shock length by 3mm overall, allowing you to use a 200mm shock which readily available without adjusting the geometry negatively. 

  • Includes a pair of standard size (12.7mm) igus® DU bushes.
  • Compatible with many Trek frames, such as Remedy / Fuel / Slash for 2016 and earlier. If your frame is 2017 + this will not work. Please contact us for an alternative.
  • Sizes are 39.9x8mm (lower) and 39.9x10mm (upper). Please note that the product photo does not reflect this. Proper photos on their way!
  • Replacement upper bolt is not included as these vary between frames, though are easily sourced from your local bolt store (10mm diameter).
  • Machined to high tolerances from Brass with Aluminium spacers.
  • Replace your out of date DRCV / RE:aktiv shock with a modern shock to greatly improve performance.
  • Very simple to install with no special tools needed.
  • Fast machining and shipping time!
  • Worldwide delivery

      Giant Anthem X2 2010

      Once again great service, my Giant Anthem X2 e-bike is ready to go, offset top bush has slackened the headstock angle and given me more clearance for getting the wiring thro' for the Tongsheng mid drive. Many thanks.


      I'm fitting a shock and needed a little extra room, found Offset Bushings, and they set me right up. The quality of these is amazing. It's too bad stock shocks (that go for $700 US and up) don't come with bushings like these. And they got to me super fast. Thanks again Offset Bushings!

      great product and great service

      I have a few older bikes I thought I might give these a shot on. I waited a bit to review to see how they work long term. Now the bushings are 7 months old with 1000s of miles and still going good. Being in the US thought it might be quite a while. Shipped FAST and when they arrived was amazed. These are a much better bushing than the plastic stuff that comes from the factory. Buy their little tool it is amazing and even use it to press some bearings on other parts. As soon as a I get my new frame, ordering another set and swap out from the get go. Thanks for great service and a great product.

      Awesome! Thank you for the kind words sir! :)

      Even if the changes are minute, I can definitely feel that my bike, a 2016 Canyon Spectral, is longer and slacker, making for a slightly more interesting and stable ride when pointed downhill.
      Given (the ratio between) the price and changes this product brings about, I'd say it's highly recommended.

      Great Service

      I ordered replacement offset bushings, initial bushing supplied were wrong size (probably down to my slightly uncommon bike), but within two days of sending an email regarding this, they got the correct size bushings to me. Phoned twice for advice, both time got straight onto someone who was very helpful and gave me some valuable technical help.
