PRO201/RS201 2WD Front Lower A-Arm Upgrade - D-164 by Yokomo  [D-164]

Reinforced aluminum lower arm for 2WD drift conversions

The Yokomo D-164 is an aluminum front lower A-arm made for use with PRO201/RS201 2WD conversion kits for drift applications. It replaces the conversion subassembly's stock lower arm to provide a stiffer pivot and more consistent geometry than typical plastic parts.

The arm includes multiple damper mounting holes to reduce the chance of the damper contacting the tyre at full lock and to allow small adjustments to damper angle and mounting position. Those mounting options let you tune roll centre, steering response, and damping leverage without changing other suspension components.

Installation note: the D-164 mounts into the conversion kit’s front lower arm location; install following your PRO201/RS201 kit instructions for correct orientation and torque. After fitting, confirm full steering travel to ensure there is no interference with tyres or steering linkages.

As an aluminum replacement lower arm for PRO201/RS201 drift conversions, the D-164 delivers extra damper mounting positions and a firmer mounting surface, supporting setup changes that prioritise steering clearance and suspension behavior.
