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

3.9mm linkage ball end caps for Mini-T and RC18

This 14 piece 3.9mm ball end cap set replaces worn linkage sockets on Team Losi Mini-T and Team Associated RC18T / RC18R platforms. The kit covers steering and suspension connections that use 3.9mm ball studs, letting you swap caps quickly during maintenance or setup changes.

The set is intended for use with Mini-T and the RC18 family. Each cap is sized to mate with standard 3.9mm ball studs and common turnbuckle or rod-end assemblies found on these models. Use the full set to restore tight seating where degraded caps are causing play at pivot points.

Fitting is straightforward: remove the old cap, verify the ball stud diameter and thread engagement, then press or screw the replacement cap into place according to your original mounting method. Once fitted, check steering throw and suspension travel for any change in free play, and re-secure adjacent linkages as required.

During setup work these small components matter for repeatable geometry. Fresh caps help keep socket seating consistent so steering and suspension responses remain predictable while you fine tune handling.
