3RACING M4WD-36/PK Double Aluminium Rollers 18-19mm for Tamiya Mini 4WD  [M4WD-36/PK]

Technical Overview of 3RACING M4WD-36/PK Rollers

The 3RACING M4WD-36/PK double aluminium rollers, supplied for Tamiya Mini 4WD applications, provide a reliable means to refine roll contact and cornering stability. These parts are engineered to fit common Tamiya chassis while offering tunable clearance via the 18-19mm arrangement.

Engineering Characteristics and Fitment

CNC-style aluminium construction reduces abrasive wear and maintains consistent contact surfaces against track walls. The dual-size configuration allows setup variance for handling balance and recovery. These rollers are compatible with MA, AR and MS chassis architectures and integrate with standard mounting points.

Race Setup Guidance

Use the smaller roller position for a lower centre of gravity and crisper turn-in, and the larger position for increased glide over uneven rail sections. Combine with bearing checks and correct spacer stack to ensure smooth rotation and predictable behaviour in competition settings.
