XRAY XB4 - Diff News (please read XRAY Statement below)

"Dear Distributor

Please note that there are some wrong information being spread around. Some customers have noticed a small play on the gear mesh between diff crown gear and pinion gear and they suggest other XB4 customers to use shims on the diff. This is however wrong. Here is official statement which will be posted also online at our web, please be aware of this:

XB4 information about shimming the differential:

Please note that the XB4 was designed by purpose with a small play (clearance) on the gear mesh between the differential crown gear and pinion gear. This small play is made by purpose. You should not use any shims on the differential to eliminate this play. The differential during operation gets warmer and expands. In case the differential will not have a sufficient play the gears may not work smoothly, may lock or even break. For this reason it is suggested not to use any shims and to build the differential as per the instruction manual."
