SERPENT 988/989 front differential drag-assisted oneway by Arrowmax AM-930005  [AM-930005]

Technical overview

This Arrowmax AM-930005 drag-assisted oneway is an RC-scale front differential accessory designed specifically for SERPENT 988 and 989 chassis. It replaces the stock oneway to change engagement behavior using a drag-assisted mechanism, intended for fine-tuning front differential response in electric RC cars.

The part is presented as a direct-fit upgrade for the specified Serpent models, with a focus on how the drag-assisted oneway alters torque transfer and engagement feel rather than on absolute numerical performance claims. Installation requires access to the front differential housing and basic RC tooling; the role of this unit is to offer a different engagement characteristic for setup tuning and handling balance.

For builders adjusting front-end behavior, this drag-assisted oneway provides an alternate engagement profile to help tune turn-in and front traction. Confirm compatibility with your Serpent 988 or 989 chassis before installation and follow standard differential service practices when fitting.
