Compact 19mm ball-race roller overview

The Tamiya 95160 Aluminum Ball-Race Roller Set J-Cup 2023 is a dedicated upgrade for Mini 4WD racers seeking reliable, low-friction rollers. These 19mm rollers use integrated ball bearings to deliver consistent rotation and help reduce drivetrain drag during competition.

Lightweight aluminium build and finish

Machined from lightweight aluminum, the rollers keep added mass to a minimum while offering good durability. The set features a blue anodized finish and Japan Cup and Tamiya logo prints for authentic event styling. Avoid using solvents on the printed areas to prevent damage.

Roller function and fitment notes

Each roller is fitted with rubber rings that cushion impacts when your car contacts track walls, helping to stabilise the chassis at speed. The rollers suit both Mini 4WD and Mini 4WD PRO cars, though some chassis or bodies may need small modifications for a perfect fit. The kit includes the small hardware required for mounting.
