Yokomo B-MAX Rear Drive Shaft Lightweight Set by Arrowmax AM-010020  [AM-010020]

Rear drive shaft role and fit

This Arrowmax AM-010020 rear drive shaft lightweight set is an RC-scale replacement part designed for use with Yokomo B-MAX touring chassis layouts. The kit focuses on reducing rotating mass at the rear driveline to refine transient response and drivetrain feel without changing core geometry.

The set ships as two pcs intended to replace the stock rear shafts and interfaces directly with the existing rear driveline mounting points on compatible B-MAX layouts. Installation requires standard hobby disassembly of the rear hub and differential housings, checking spline engagement and retaining hardware torque after initial installation.

Tuning role: swapping to lighter rear shafts can reduce rotational inertia on acceleration and direction changes, which may make throttle and steering responses feel crisper. Expect changes to vehicle balance to be subtle and to interact with suspension, gearing, and motor/ESC setup; adjust those systems incrementally when testing.

Use this lightweight rear drive shaft set when you want a targeted reduction in rotating mass at the rear of a Yokomo B-MAX chassis to evaluate effects on acceleration and handling response during setup sessions.
