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

Reduced-mass front drive shafts for Yokomo B-MAX4

This Arrowmax AM-010021 front drive shaft set is a purpose-built replacement for the Yokomo B-MAX4 platform, supplied as a matched two-piece pair for the left and right front positions. The lightweight construction is intended to lower rotating mass in the front drivetrain, helping deliver more predictable behaviour under acceleration and during steering changes on 1/10 touring-style cars.

Fitting follows standard front shaft replacement steps: remove wheel and hub, withdraw the old shaft from the gearbox and knuckle, then install the new unit while checking spline engagement and endplay. Confirm fastener torque and ensure free rotation through the full steering sweep before running. No chassis modifications are required for stock B-MAX4 steering and front hub geometry.

Setup and maintenance notes: trimming rotating mass at the front can reduce drivetrain inertia and sharpen throttle bite, which is useful when dialling in balance and traction for on-road tracks. Inspect splines and mating surfaces regularly for wear and play, and replace both shafts if you see excessive looseness to preserve consistent handling.
