Team Associated RC18T RC18R 3Racing RC18-008/SI Aluminum Caster Block Race Ready Upgrade  [RC18-008/SI]

Precision Caster Block in Aluminum for RC18T and RC18R

Fit this 3Racing RC18-008/SI aluminum caster block to your Team Associated RC18T or RC18R to replace the stock plastic piece and gain a firmer, more accurate front end. The machined unit is aimed at better control under sustained use.

Precision Machining for Better Handling

High tolerance machining gives the caster block a tight fit that reduces play and improves steering feedback. The aluminium body is less prone to deformation, which helps maintain setup consistency lap after lap.

Simple Replacement, Track Ready

Designed as a direct replacement for the RC18T and RC18R front assembly, the RC18-008/SI installs with the existing hardware and keeps original suspension geometry intact. It is a practical upgrade for track days and local competitions.
