Yokomo B-MAX4 Aluminium Mid Drive Shaft Set for Racing - Arrowmax AM-010022  [AM-010022]

Aluminium Mid Drive Shafts for B-MAX4

This Arrowmax AM-010022 mid drive shaft set is supplied as a lightweight replacement for use with the Yokomo B-MAX4 chassis. Components are machined from aluminium alloy to lower rotating mass while retaining the mid-gear geometry required by standard B-MAX4 drivetrains.

The focus is on stable, repeatable on-track behaviour and a simple fitment process. Use the set as an upgrade or spare when adjusting geartrain inertia for crisper throttle transitions and improved transient handling.

Fitment notes: install the shafts in place of the original mid drive parts following the chassis service procedure; verify shaft alignment and clearances after assembly and ensure the shaft ends mate cleanly with existing dogbones or couplers. No additional chassis modifications are expected for standard setups.

For competitive drivers and workshop tuners using the B-MAX4, the Arrowmax AM-010022 mid drive shaft set provides a practical way to reduce rotating mass and refine drivetrain response without altering the chassis layout.
