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

3.9mm ball end cap replacement for Mini-T and RC18 linkages

This 14 pcs 3.9mm ball end cap set is a direct replacement option for Team Losi Mini-T and Team Associated RC18T / RC18R linkage sockets. The caps suit steering and suspension linkages that use 3.9mm ball studs and are intended for straightforward swaps during maintenance or setup tuning.

The kit is specified for Mini-T and the RC18 family and pairs with common 3.9mm ball studs and standard turnbuckle or rod-end assemblies used on these cars. Fit the set when worn sockets introduce play or when matching parts during a handling setup.

Installation takes only a few steps: remove the old cap, confirm the ball stud diameter and how the original was mounted, then press or thread the new cap into place according to your chassis hardware. After fitting, check for any change in steering free play and suspension articulation and make final linkage adjustments.

In fine tuning, consistent socket seating keeps your geometry repeatable. Replacing tired caps restores reliable joint seating so steering and suspension reactions remain consistent run to run.
