Roco Air piggy back shock service

Here is the video guide for the Roco Air piggy back shocks. The TST and the RC are the same shock units with the exception of the mechanical TST valve vs. the shimmed compression valve in the RC, they are interchangeable so you can convert between the two.

The service is complex so if you are in any doubt please send your shock to a specialist.

The seal kit is Y8501251/P and costs £59.95 


  1. Hey Dan, great guide! I was wondering if the IFP heights you listed in the Roco RC Coil video can be used in the Air TST R... Otherwise, could you post the right IFP heights here?

    Thanks in advance!

  2. just use the same IFP heights as the coil and you are back in business!

  3. hello,
    i'd like to ask, what can i change internaly on an "Air tst r" 200X50mm in order to increase the stroke up to 57mm??? (if this is possible)

    1. its not an easy conversion, its a new air can, internal piston and main tube. It would be cheaper to buy another shock, sorry!
