About the Aluminum Ball-Race Rollers

Roller Upgrade

These 11mm ball-race rollers help improve a Mini 4WD's chances of finishing a race by enhancing stability during runs. Their bowl-shaped design helps the car slide back down if it rides up onto a lane wall, assisting it in regaining the course. They can also be used as part of racing setups to support smoother, more controlled performance in tight lanes.

Features:

• Made from lightweight aluminum
• Built-in 520 ball bearings for smooth rotation
• Bowl Shape for reduced hang ups on track wall
• Compatible with Mini 4WD and Mini 4WD PRO cars
