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

Intro to the Tamiya 95148 HG 19mm rollers

The Tamiya 95148 HG 19mm Aluminum Ball-Race Rollers are an upgrade aimed at Mini 4WD competitors. As part of the Japan Cup 2021 releases, they come in a black anodised finish with blue decorative printing that complements race builds. Each roller runs on 520 ball bearings to deliver smooth rotation during competitive runs.

Materials and fitting guidance

Crafted from lightweight aluminium, these 19mm rollers balance robustness with minimal added mass. They fit many Mini 4WD and Mini 4WD PRO platforms, but some vehicles may need minor body or chassis modification to clear the rollers. Mounting hardware including spacers and screws is provided to help with setup.

Benefits on the circuit

Installing these ball-race rollers can enhance corner stability and cut down rolling friction, which helps maintain momentum and faster lap times. Their ringless construction lowers drag for cleaner transitions, making them a good choice for technical or twisty circuits where precision is important.
