Tamiya 3RACING M4WD-31/PK 17mm Pink Aluminum Ringless Ball Race Rollers  [M4WD-31/PK]

Quick look at the Tamiya Mini 4WD 17mm Pink Rollers

The Tamiya Mini 4WD 17mm Aluminum Ball Race Rollers in pink are a compact upgrade for racers wanting crisper cornering and steadier line holding. The ringless design keeps weight down while the aluminium body provides a solid yet light option for race setups.

Track performance and chassis fit

These 17mm aluminum ball race rollers cut friction against track walls to smooth out transitions and keep speed through bends. That advantage is most clear on technical, twisty layouts. They suit a broad range of Tamiya chassis, including MS, MA, and AR types.

Practical gains during racing

Fitting these rollers typically improves cornering precision and can help lower lap times by reducing slowdowns on turns. Their ringless form lowers rotating mass without compromising stability, a useful balance for club and practice sessions.
