The 3Racing RC18-008/BU aluminum caster block is made for Team Associated RC18T and RC18R models to deliver improved front end durability and a firmer steering feel. It is a sensible upgrade for drivers who want more reliable handling from their front suspension.
Manufactured from aluminium to resist wear and impacts, these caster blocks reduce unwanted movement at the steering knuckle and deliver a closer, more repeatable steering response. The precise fit helps keep wheel alignment consistent lap after lap.
Fitting this aluminium caster block is a straightforward replacement of the stock piece and brings immediate gains in toughness and steering consistency. It pairs well with refreshed bearings and steering hardware when tuning for performance.
