Serpent 988/989 Front Differential Oneway for Tuning - Arrowmax AM-930005  [AM-930005]

Overview for tuners

Arrowmax AM-930005 is a drag-assisted front oneway designed to fit SERPENT 988 and 989 front differentials. It replaces the stock unit to alter engagement characteristics, offering a different ramp of drag that can be useful when dialling in front traction and turn-in response.

This component is presented as a direct replacement for the listed Serpent models, focusing on how the drag-assisted mechanism modifies torque transfer and engagement feel rather than claiming specific numerical gains. Installation involves access to the front differential and common RC hand tools; basic mechanical familiarity will make the swap straightforward.

When you need a different front engagement profile for setup balance, the Arrowmax AM-930005 provides an alternate option to tune turn-in and front traction. Verify compatibility with your Serpent 988 or 989 before fitting and observe correct differential servicing.
