This Arrowmax AM-010021 front drive shaft set is a purpose-made RC-scale replacement for the Yokomo B-MAX4 platform, supplied as a two-piece set for the left and right front axles. It is presented as a lightweight option to reduce rotating mass in the drivetrain, with a focus on predictable behaviour during acceleration and direction changes on 1/10 touring-style setups.
Installation follows standard front drive shaft replacement steps: remove the wheel and hub, extract the existing shaft from the gearbox/knuckle assembly, and install the replacement while checking spline fit and endplay. Confirm fastener torque and verify free rotation through the steering sweep before running. No special modifications are required if the set is used with stock B-MAX4 steering and front hub geometry.
Tuning role and service notes: reducing rotating mass at the front reduces drivetrain inertia and can sharpen initial throttle response, which helps when fine-tuning balance and traction in on-road conditions. Routine inspection for play, wear at the splines, and proper engagement with the steering knuckle is recommended; replace the pair at the first sign of excessive wear to maintain consistent handling.
Use this set when you need matched front shafts for regular maintenance or a lightweight option during setup changes on B-MAX4-based touring builds.
