The Reflex Racing Lightweight Ball Diff V4 is a high quality ball diff that is super light while maintaining great engagement and acceleration.
The ball diff comes standard with super hard steel diff rings, 7075 T6 Aluminum diff shaft, carbide diff balls, hard o-ring for tighter adjustment, and a specially designed 10 ball spur gear and lightweight 7075 aluminum shaft and diff parts. The V4 diff now also comes with a molded spur and spur gear covers. The spur gear is super durable, quieter and much longer lasting. The covers are now about 50% lighter than the aluminum variants, which gets the weight down to a scant 6.6g with covers and 5.8g without (including the left hub).
