Limited Tamiya 95148 HG 19mm Aluminum Ball-Race Rollers Ringless J-Cup 2021  [95148]

Product brief for Tamiya 95148 HG 19mm rollers

The Tamiya 95148 HG 19mm Aluminum Ball-Race Rollers provide a focused upgrade option for Mini 4WD fans. Issued as part of the Japan Cup 2021 collection, the rollers feature black anodising with blue accent print for a tidy, competition-ready look. Equipped with 520 ball bearings, they promote consistent, low-friction rotation during runs.

Compatibility and construction details

Made from lightweight aluminium, these 19mm rollers offer a good compromise between durability and weight savings. They are compatible with Mini 4WD and Mini 4WD PRO chassis types, although particular bodies might need slight modification to fit. Spacers and mounting screws are supplied for straightforward installation.

How they affect handling on course

Adding these ball-race rollers can improve line holding and reduce rolling resistance, which helps keep lap times competitive. The ringless format cuts parasitic drag for smoother transitions, which is beneficial on twisty, technical layouts where control and responsiveness are key.
