Mini 4WD Double Aluminum Roller Set 8-9mm M4WD-33/GO by 3Racing  [M4WD-33/GO]

M4WD-33/GO double aluminum rollers for Mini 4WD

This double-roller assembly provides two concentric 8-9mm aluminum rollers with a gold anodized finish. These aftermarket spare rollers are intended for Mini 4WD chassis that accept 8-9mm roller mounts and focus on solid construction and proper fit rather than performance guarantees.

For builders with experience: these rollers replace worn plastic parts and give a more consistent contact surface where rules allow double rollers. Confirm rail and side stay clearances before fitting, since a double arrangement increases mounted width and can interact with stabilisers and side guards.

Fitment follows standard roller mounting practice. Use the correct shaft diameter and low-friction hardware, tighten fasteners securely without deforming the thin aluminium, and inspect regularly for burrs or wear.
