Yokomo B-MAX4 Front Drive Shaft Set by Arrowmax AM-010021 Lightweight Touring Upgrade  [AM-010021]

Front drive shaft pair for improved front-end response

The Arrowmax AM-010021 front drive shaft set is manufactured as a direct replacement for the Yokomo B-MAX4 and is supplied as two shafts for the left and right front positions. This lightweight option is intended to reduce rotating mass in the front drivetrain and promote a more predictable response during acceleration and steering transitions on 1/10 touring vehicles.

Installation uses standard procedures: remove the wheel and hub, extract the existing shaft from the gearbox/knuckle, and fit the new shaft while checking spline fit and endplay. Ensure fasteners are torqued correctly and verify free rotation through the steering sweep. No special alterations are needed with stock B-MAX4 front hardware.

Tuning notes and service: cutting rotating mass at the front lowers drivetrain inertia and can sharpen initial throttle bite, aiding balance and traction adjustments. Carry out routine checks for spline wear, play and correct engagement with the steering knuckle, and replace both shafts if wear is evident.
