Team Associated RC18T/RC18R Aluminum Steering Caster Block RC18-008/SI by 3Racing  [RC18-008/SI]

Upgraded caster block for RC18T/RC18R

This aluminum caster block replaces the original plastic steering block used on Team Associated RC18T and RC18R and is identified as RC18-008/SI. It gives a firmer mounting point for the front suspension, helping to control flex while preserving the vehicle's original geometry.

Installation follows standard hobby procedures: remove the factory caster block, transfer bearings and any spacers, mount the new aluminum block to the upright and refit the original hardware. No specialist tools are required beyond common hex drivers, and correct torqueing reduces the chance of steering bind.

The component should be treated as a tuning accessory rather than a setup overhaul. By increasing mounting stiffness it helps keep steering alignment stable under load, which benefits handling when adjusting caster, camber or toe settings. Pair with serviced bearings and aligned links for best results.

Maintenance and tuning reminders

• Confirm caster and toe after fitting to ensure your setup targets are maintained.
• Reuse original seals and spacers where applicable to keep bearing preload consistent.
• Cycle suspension through full travel and confirm there is no binding before running.
