Info direct from XRAY regarding XB9 Shocks

Dear Distributor

There is some confusion and misinformation about the tolerance of the XB9 shock pistons between the customers. The XB9 pistons were designed and produced cca 0.2mm smaller than the diameter of the shock body. This is NOT a manufacturing fault but this is made by purpose to allow the shock pistons to move ultra smoothly. Same tolerance we use for other cars and same tolerance is used by some other competition cars as well. So there is no fault, everything is made by purpose.

We can of course make optional pistons which will have less gap between the piston and shock body but this will require to use different shock oil and when it is colder it makes more difficult to set-up the shocks, the setting is more sensitive and this is of course more complicated for regular drivers.

Most of the "problems" are created by few drivers, some of them team drivers, who start the issue and it rolls like snowball. The Kyosho shocks which are considered as bench mark have the same toleracne of pistons, same number of holes, same angle of pistons, same diameter of holes, the XRAY o-rings seal perfectly while the shocks move freely and the shock membranes are very good as well.

In case you will get any questions or comments about this matter you will know the above information .
We will update the XB9 and shock piston information to make sure the information is also available publicly. Please feel free to provide this info to your customers.

Thanks and with best regards
