XRAY have introduced a new 41T steel bevel gear for the XB4’20. CNC-machined from HUDY spring steel and ultra-hardened making it super strong, reliable and with much higher life span, the 41T bevel gear is specially designed to be used with the large volume differential when smaller front tires are used. The 41T bevel gear will result in an overdrive characteristics that will help to compensate for the larger rear tires. XRAY’s unique split design of the gear differential features a separate lightweight crown gear and a separate diff cover. The split design results in significantly lower weight and improves the service comfort.
