Infinity IF18 Front Differential Oneway Upgrade - Arrowmax AM-930002  [AM-930002]

Front diff drag-assist unit for Infinity IF18

The Arrowmax AM-930002 is a drag-assisted oneway designed for the front differential of the Infinity IF18 touring car chassis. As a direct replacement, it alters torque transfer on deceleration and at low speeds to provide a predictable drag characteristic for tuners balancing front traction and steering response.

This part is made to fit inside the IF18 front differential housing without chassis modification; always verify internal clearances and fitment against your diff internals before final assembly. The unit is intended to complement standard IF18 diff setups and to work alongside suspension and tire tuning rather than replace those adjustments.

Installation requires diff strip-down, removal of the existing oneway, and fitting of the AM-930002 while maintaining correct shim and bearing positions to ensure reliable engagement. After fitting, controlled track testing and small adjustments to differential preload and tyre setup will help you arrive at the desired front-end behavior.
