Yokomo B-MAX4 Drive Shaft Mid Lightweight Set by Arrowmax AM-010022  [AM-010022]

Mid Drive Shaft for B-MAX4

This Arrowmax mid drive shaft set is an RC-scale replacement intended for use with the Yokomo B-MAX4 chassis. The package is a lightweight mid-shaft option built to reduce rotating mass compared with stock components while maintaining the geometry needed for standard B-MAX4 drivetrains.

Design emphasis is on predictable on-track behavior and straightforward fitment into the B-MAX4 mid-gear area. The set serves as a direct upgrade or spare part during routine maintenance, setup changes, or geartrain tuning where lower inertia at the driveshaft helps refine throttle response and transient handling.

Installation notes: the shafts install in place of the original mid drive components and require normal disassembly of the RC gearbox or mid-section as per the chassis manual; check alignment and clearance after fitting and verify that drivesuffix interfaces mate with existing dogbones or couplers. No special modifications are required for standard B-MAX4 layouts.

For RC racers and tuners running the B-MAX4 chassis, this Arrowmax AM-010022 mid drive shaft set is a compact upgrade option to reduce rotating mass and support finer drivetrain tuning without changing chassis layout.
