RC18T/RC18R Front Aluminium Caster Block RC18-008/BU for Team Associated by 3Racing  [RC18-008/BU]

Front caster block in aluminium for RC18 platforms

This lightweight machined aluminium caster block is intended as a replacement part compatible with Team Associated RC18T and RC18R cars. The aluminium construction offers greater rigidity compared with OEM plastic, acting as a solid mounting point for the steering knuckle while influencing caster and steering geometry.

Installation is simple for hobbyists familiar with chassis work: remove the stock caster block per the manual, transfer bearings and pins as needed, and secure the aluminium unit with the original hardware. After fitting, inspect steering free play, linkage geometry and bearing seating to confirm correct alignment and safe running.

In tuning terms, the aluminium block reduces front-end compliance so steering input is relayed more directly, helping camber and caster adjustments behave predictably during tight cornering or practice sessions. It suits pilots wanting a durable, drop-in upgrade to sharpen front-end control on their RC18T or RC18R.
