REFLEX RACING - LIGHTWEIGHT BALL DIFF V4

RX515V4 What makes the Reflex Ball Diff Special? Attention to details. We worked on sourcing the highest quality materials and ended up with a light weight ball diff that has better 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, our 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).Instructions -https://www.reflexracing.net/assets/images/Reflex%20Racing%20V2%20Ball%20Diff.pdf?rdm=BFC5F24445B0
