Tamiya 94792 JR O Ring Set (6pcs) - Suitable for 17mm and 19mm Rollers

The Tamiya 94792 JR O Ring Set provides six replacement rings aimed at Mini 4WD hobbyists wanting more predictable roller behaviour. Sized for both 17mm and 19mm rollers, these O-rings help preserve grip and reduce roller movement during racing.

Compatibility details

These O-rings are compatible with Tamiya 15160 19mm Aluminum Ball-Race Rollers, 15161 17mm Aluminum Ball-Race Rollers, and 15404 19mm Aluminum Ball-Race Rollers (5-Spoke Type). Their secure seating keeps the roller in better contact with the track surface and reduces slippage in corners.

How they help on track

Maintaining steady corner speed is vital in Mini 4WD. Fitting the Tamiya JR O Ring Set can improve turn-in and mid-corner stability, giving a more consistent line through technical sections where small gains count.
