NEXX Racing CNC Ball Diff Shaft

The NEXX Racing NX-232 is a CNC-machined ball differential shaft for Mini-Z MR02/MR03 chassis, built as a precision replacement for the stock diff shaft inside NEXX Racing's ball differential upgrades. A true, precisely machined shaft is critical to how smoothly a ball differential operates — any flex or runout in the shaft translates directly into inconsistent power delivery and reduced diff life.

CNC machining holds tighter tolerances than a stock stamped or molded shaft, giving the differential a smoother, more consistent feel through corners and off the throttle. It's a precise, direct-fit replacement for MR02/MR03 differential builds, making it a straightforward way to freshen a worn diff shaft or complete a full differential rebuild.

A useful spare part for any competitive Mini-Z racer running a ball differential, keeping the diff performing like new. Sold individually.
