Infinity IF18 Front Oneway Replacement - Arrowmax AM-930002  [AM-930002]

Tuned drag oneway for the IF18 front differential

The Arrowmax AM-930002 is a drag-assisted oneway made for use in the front differential of the Infinity IF18 touring car. Fitted as a direct replacement, it modifies how the front diff carries torque under braking and low-speed load, giving racers a consistent drag baseline for balancing front traction and steering response.

This RC-scale component is intended to sit inside the IF18 front diff housing without needing chassis changes; check the diff internals and clearances before final fitment. The AM-930002 integrates with standard IF18 diff assemblies and is meant to complement suspension and tyre tuning rather than replace those setup elements.

Fitting involves disassembling the diff, removing the stock oneway, and installing the AM-930002 while keeping shims and bearings in their correct positions to ensure proper engagement. Post-install, perform track sessions and make incremental tweaks to diff preload and tyre choice to tune the front-end feel.
