Tamiya 94792 JR O-Ring Set 6pcs - 17/19mm Roller Upgrade  [94792]

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

The Tamiya 94792 JR O Ring Set contains six O-rings intended as replacements for Mini 4WD rollers. These rings are produced to fit common 17mm and 19mm roller sizes and help improve roller traction and consistency under race conditions.

Which rollers and what they do

Compatible with Tamiya models 15160 (19mm Aluminum Ball-Race Rollers), 15161 (17mm Aluminum Ball-Race Rollers), and 15404 (19mm Aluminum Ball-Race Rollers, 5-Spoke Type), the O-rings maintain a steady interface between roller and track to reduce slips and aid cornering.

Practical racing advantages

On technical tracks where control matters, the Tamiya JR O Ring Set helps the car track predictably through turns. Better roller traction means fewer wide exits and more consistent lap times when set up correctly.
