3RACING MIF-011 Mini Inferno ST Bearing Upgrade (8 pcs)  [MIF-011]

Refine your Mini Inferno's drivetrain with ball bearings

For a noticeable reduction in drivetrain drag, the 3RACING MIF-011 Ball Bearing Set is a compact upgrade for the Kyosho Mini Inferno ST and ACME NB16 Racing models. This eight-piece kit swaps in for standard bushings to promote smoother rotation and longer component life.

Improved rolling and component life

Replacing bushes with these ball bearings reduces friction at wheel and shaft interfaces, which helps keep speeds steady and lowers wear on parts. That is helpful whether you are timing laps or enjoying spirited runs on mixed surfaces.

Compatibility notes and installation tips

Installation is straightforward for experienced hobbyists: remove existing bushings and press the 3RACING bearings into place. They work with several Mini Inferno variants so you can standardise upgrades across multiple models.
