Caster Alignment Gauge for XRAY X20/X23 - am-174040-c by Arrowmax  [am-174040-c]

Setup tool for exact caster readings

This RC-scale adapter is an accessory for checking caster angle on XRAY X20 and X23 models. It integrates with the 4D setup system to deliver repeatable datum points when you measure or tweak caster during setup work.

Sold as a pair, the part is shaped to match the locating features on the specified chassis so pointers land consistently between runs. Use it to verify left/right symmetry or to lock in a starting point before fine tuning suspension and steering geometry.

Fitting is direct: align the adapter to the chassis locating points or setup plate, secure using the chassis fasteners, then mount the caster pointer according to your 4D setup procedure. Always confirm clearance around servo linkages and moving suspension before final tightening.

This alignment gauge is intended as a practical setup aid for touring car racers seeking predictable caster measurements at the track or workshop.
