Tamiya 94792 Mini 4WD JR O-Ring Pack (6) for 17/19mm Rollers  [94792]

Tamiya 94792 JR O Ring Set (6pcs) for 17mm and 19mm Roller Use

The Tamiya 94792 JR O Ring Set offers six spare O-rings for Mini 4WD hobbyists who want improved roller contact. Sized for both 17mm and 19mm roller types, these O-rings help preserve grip and reduce unwanted movement on the track.

Compatibility and purpose

These rings pair with Tamiya 15160 19mm Aluminum Ball-Race Rollers, 15161 17mm Aluminum Ball-Race Rollers, and 15404 19mm Aluminum Ball-Race Rollers (5-Spoke Type). They secure the roller surface to maintain continuous track contact and minimise slippage during cornering.

Why racers fit them

Precise handling is essential in Mini 4WD events. Fitting the Tamiya JR O Ring Set helps rollers bite into the guide rails more reliably, making turns smoother and the car more stable when racing on technical layouts.
