Mini-T and RC18 Ball End Cap Set 3.9mm MT-028/V2 by 3Racing  [MT-028/V2]

Technical 3.9mm ball end cap kit for competitive setups

This 14-piece 3.9mm ball end cap set provides exact-fit replacement sockets for steering and suspension linkages used on Team Losi Mini-T and Team Associated RC18T / RC18R. The kit is intended to restore consistent ball seating where worn caps have introduced play that affects geometry and handling repeatability.

Use these caps to pair with standard 3.9mm ball studs and common turnbuckle or rod-end hardware found on the listed platforms. Replace degraded caps during routine teardown or when refining steering and suspension alignment to retain predictable response under tuning iterations.

Installation procedure: remove the existing cap, verify ball stud diameter and original mounting method, then install the replacement by pressing or threading as required. After fitting, inspect steering sweep and suspension articulation, and re-tension surrounding linkages to factory or preferred setup settings.

In race preparation, consistent socket seating contributes to repeatable geometry. Renewing worn caps reduces variable free play so chassis behaviour is reliable between setup passes.
