Yokomo B-MAX4 Low-Inertia Mid Drive Shafts for Tuners - Arrowmax AM-010022  [AM-010022]

Performance Mid Drive Shafts for B-MAX4

This Arrowmax AM-010022 mid drive shaft set is an RC replacement intended for the Yokomo B-MAX4 chassis, offering a lighter mid-shaft solution that reduces rotating mass while keeping the required geometry for standard B-MAX4 drivetrains.

The product aims to enhance predictable handling and simplify trackside adjustments. Fit it as a direct upgrade or as a spare during routine servicing or when tuning drivetrain inertia to sharpen transient response.

Fitting advice: install these shafts in place of the factory mid components by following the gearbox or mid-section disassembly steps in the chassis manual; confirm alignment and clearance after assembly and ensure the driveshaft ends engage correctly with current dogbones or couplers. No special chassis alterations are required for typical B-MAX4 setups.

For tuners and racers using the B-MAX4, the Arrowmax AM-010022 mid drive shaft set is a compact upgrade to reduce rotating mass and help achieve more responsive drivetrain behaviour without changing chassis layout.
