XRAY Active Diff segments are CNC-machined from very tough steel, and have very precisely-machined "V" ramp grooves with 90° angle for easy engagement/disengagement. The segment is hardened to ensure long life and durability. The segments are laser engraved with "90°" for easy and instant recognition. Set of 2.

The 90° segments provide a very good balance of performance between on- and off-power. On-power the diff becomes hard after a brief delay. Off-power the diff becomes free after a brief delay. For use on medium traction tracks.

Active Differential Segments are available in three different alternatives:
#352123 - 60°
#352125 - 90°
#352127 - 120°
