Tamiya 94617 10mm Guide Roller Ball Bearing Set - Limited Edition  [94617]

Tamiya 94617 - Exclusive 10mm Guide Roller Bearings for Mini 4WD

The Tamiya 94617 10mm Diameter Guide Roller Ball Bearing Set is designed to improve rolling efficiency for Mini 4WD models. As a limited edition Grade-Up component, it reduces rotational friction so guide rollers rotate with greater ease, helping your setup run more predictably during races or practice laps. The 10mm diameter is a touch smaller than the typical 11mm bearings and is compatible with a broad selection of Mini 4WD chassis.

Suited to both competitive tuners and detail builders, these bearings deliver subtle but meaningful gains in handling and smoothness. They are an effective, low-effort upgrade for anyone seeking better roll characteristics without altering core chassis geometry.
