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

Fitment and purpose of the rear shafts

The Arrowmax AM-010020 rear drive shaft lightweight set is an RC replacement item created for Yokomo B-MAX touring chassis arrangements. The parts are designed to reduce rotating mass at the rear driveline to sharpen transient response while maintaining the original chassis geometry.

The two-piece set replaces the stock rear shafts and couples directly with the existing rear driveline mounting points on supported B-MAX variants. Installation follows standard model hobby practice: disassemble the rear hub and differential housings, confirm correct spline engagement and torque the retaining hardware after initial testing.

Tuning advice: lighter rear shafts reduce rotational inertia under acceleration and quick steering transitions, which can yield more immediate throttle and steering feedback. Changes to balance will usually be small and will interact with suspension tuning, gearing and motor/ESC setup, so progress with small adjustments while evaluating performance.

Use this lightweight rear drive shaft set to make a targeted reduction in rear rotating mass on a Yokomo B-MAX chassis and assess the resulting effects on acceleration and handling during setup laps.
