Aluminum caster block for RC18T/RC18R

This aluminum caster block is an RC-scale replacement part designed to fit Team Associated RC18T and RC18R platforms. Machined from aluminum for improved rigidity compared with typical stock plastic parts, it serves as a direct mounting point for the front steering knuckle and influences steering geometry and caster settings.

Installation is straightforward for hobbyists: remove the original caster block following the chassis manual, transfer any existing pins or bearings, and secure the aluminum unit with the chassis hardware. After fitment, check steering free play, steering linkage alignment, and wheel bearing seating to ensure intended geometry and safe operation.

In tuning terms, this caster block helps stabilize steering feedback and reduces flex at the front end, which can make camber and caster adjustments more consistent during aggressive runs or track sessions. It is suitable for hobbyists seeking a durable drop-in part to refine front-end response on the RC18T/RC18R.
