RC18T/RC18R Competition Aluminium Caster Block RC18-008/BU by 3Racing  [RC18-008/BU]

Competition aluminium caster block for RC18 chassis

This CNC-style machined aluminium caster block is specified as an upgrade for Team Associated RC18T and RC18R platforms. The rigid aluminium body reduces compliance compared with standard plastic parts, providing a precise mounting surface for the front steering knuckle and improving repeatability of caster geometry under load.

Installation requires typical workshop steps: remove the OEM caster block per the chassis service manual, transfer bearings and locating pins, then torque the replacement unit to chassis specifications using the existing hardware. After fitting, confirm steering free play limits, steering linkage geometry and bearing seating to ensure predictable handling and component longevity.

From a setup and tuning perspective, the stiffer aluminium member reduces front-end deflection, stabilises steering feedback and makes camber and caster adjustments more reliable during competitive running. It is intended for racers seeking a high-precision, drop-in upgrade to improve front-end consistency on RC18T and RC18R vehicles.
