XRAY X20/X23 caster pointer adapter by Arrowmax am-174040-c  [am-174040-c]

Caster pointer adapter for XRAY

This adapter is an RC-scale caster pointer accessory intended for precise caster angle checking on XRAY X20 and X23 platforms. It works with the 4D setup system interface to give repeatable reference points when you measure or adjust caster during chassis setup.

The part fits as a pair and is designed to align with existing setup fixtures on the specified chassis, allowing consistent pointer placement between runs. Use it when you need to compare left/right caster readings or lock in a baseline before fine tuning suspension or steering geometry.

Installation is straightforward: mount the adapter to the setup plate or designated locating points on the chassis, secure with the original fasteners, then attach the caster pointer as required by your 4D setup tooling. Check fitment and clearances before final tightening to avoid contact with servo linkages or suspension components.

This accessory serves as a setup aid for RC touring cars, providing stable pointer positioning for caster checks and incremental adjustments during track setup.
