Precision ball studs for Mini-T race setups

This MT-031 3.9mm aluminium ball stud set is produced for direct-fit replacement at Team Losi Mini-T linkage points. The kit contains 10 CNC-friendly machined aluminium studs designed to replace original plastic or steel posts where Mini-T compatibility is required.

Fitment procedure: remove the factory studs from linkage arms or bulkhead, inspect thread engagement, and fit the aluminium studs. Torque to a firm setting without exceeding the tiny thread limits to prevent stripping; use appropriate small drivers and confirm unrestricted articulation of the ball ends within the mating cups.

Setup impact and serviceability: aluminium studs change pivot stiffness and wear patterns at steering and suspension links, offering a consistent metal interface that reduces flex under load compared with softer plastics. This helps drivers lock in steering geometry and improves repeatability during tuning cycles.

What thread checks should I perform before fitting?

Confirm stud thread pitch and engagement depth by hand-starting each stud; ensure the bulkhead or link retains at least the original number of turns of engagement before final torque.

How do aluminium studs affect tuning consistency?

Aluminium provides a stable metal bearing for ball cups, reducing movement variance seen with soft plastics and improving repeatable toe and camber settings across runs.

Recommended maintenance intervals?

Inspect studs and ball cups after the first few sessions for seating and wear, then include them in routine checks; replace cups if deformation is observed to maintain precise pivot action.
