Tamiya 3RACING M4WD-31/LB 17mm Light Blue Ringless Aluminium Rollers  [M4WD-31/LB]

Overview of 17mm Ringless Ball Rollers by Tamiya

The Tamiya Mini 4WD 17mm Aluminum Ball Race Rollers in light blue are designed to lower rotating mass and smooth cornering responses. Their ringless construction helps reduce drag while keeping a compact footprint on the chassis.

Fitment and Build Characteristics

Constructed from aluminium for lightness and durability, the 17mm rollers keep steady contact with track guides. They are compatible with common chassis like MS, MA, AR and VS, allowing straightforward installation into most setups.

Performance Impact on the Track

These rollers reduce unwanted lateral movement and aid consistent line holding, particularly on circuits with sharp bends. The design supports quicker recovery out of corners and steadier lap times when tuned correctly.
