KF2 shock seal sizes
 

Looking to buy in some better quality shock seals - anyone else do this? Any idea on exact dimensions?

The o-rings for the Schumacher 1/10th off-road cars all use an o-ring of size 1/8 according to the manuals and diagrams. The compound of the o-ring is really important so that with the oils we use it does not well too much. Also the compound must be a friction free as possible so as not to alter the action of the shaft in the shock. The std o-rings vs the blue pro o-rings are an example of this.
