Tamiya 94792 JR O Ring Set - 6 O-rings for 17mm and 19mm Rollers

The Tamiya 94792 JR O Ring Set supplies six replacement O-rings for Mini 4WD racers who want to fine tune roller traction on their cars. These robust rings are sized for 17mm and 19mm rollers to help maintain grip and steady rotation during faster runs.

Fitment and function

These O-rings are compatible with Tamiya's 15160 19mm Aluminum Ball-Race Rollers, 15161 17mm Aluminum Ball-Race Rollers, and 15404 19mm Aluminum Ball-Race Rollers (5-Spoke Type). When fitted correctly they keep the roller face in consistent contact with the track, cutting down on slip and aiding cornering performance.

On-track benefits

Control through bends is a key factor in Mini 4WD racing. The Tamiya JR O Ring Set improves the roller surface traction, allowing smoother turns and more predictable handling, especially on technical circuits where consistent contact matters.
