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

Machined front caster block compatible with RC18T and RC18R

This machined aluminum caster block is a direct-fit replacement compatible with Team Associated RC18T and RC18R platforms. Built from solid aluminium to reduce flex versus stock plastic parts, it provides a firm mounting surface for the front steering knuckle and helps maintain intended caster geometry.

Fitting is straightforward for experienced hobbyists: follow the chassis manual to remove the original caster block, transfer any pins or bearings, and fasten the aluminium unit with the existing chassis hardware. After installation, verify steering free play, linkage alignment, and wheel bearing seating for correct setup and safe operation.

From a setup perspective, the stiffer aluminium block tightens steering feedback and lowers front-end compliance, making camber and caster settings more consistent during spirited running or timed practice. It is aimed at builders who want a robust drop-in upgrade to sharpen front-end response on RC18T and RC18R cars.
