Precision aluminium caster block for tuned RC18T and RC18R setups

The 3Racing RC18-008/BU aluminium caster block is manufactured to provide a rigid, precisely machined mounting point for Team Associated RC18T and RC18R steering knuckles. This component reduces compliance at the front end, allowing finer steering inputs and more predictable handling when optimising suspension settings for racing.

Engineered for setup consistency and endurance

CNC style machining yields tight tolerances for repeatable alignment and minimal unwanted movement. The aluminium construction offers improved resistance to deformation under load, which helps maintain intended caster and steering geometry during aggressive cornering and frequent track sessions.

Installation and tuning considerations

Installation is a direct replacement for the stock blocks; technicians should check fitment and re-evaluate toe and steering trim after fitting. For competitive use, pair this unit with fresh bearings and secure fasteners to fully capitalise on the improved rigidity and feedback.

How does reduced compliance affect tuning choices?

Lower compliance yields crisper steering feedback, which can make the car more responsive to small setup adjustments; expect to fine tune toe and steering end points after installation.

Are there recommended complementary upgrades?

For optimal performance, inspect and, if needed, replace bearings, ball studs and steering hardware to ensure the full assembly benefits from the reduced flex of the aluminium block.

Will aluminium change dynamic handling under load?

Yes, stiffer mounting points tend to preserve steering geometry under load, which improves predictability at the limit and supports consistent lap times when combined with tuned suspension settings.
