1/32 Mini 4WD Double Aluminum Rollers 18-19mm - Tamiya M4WD-36/GO  [M4WD-36/GO]

Tamiya M4WD-36/GO double aluminum rollers 18-19mm gold

These double aluminum rollers are supplied as replacement components for 1/32 Mini 4WD cars. The design focuses on machined aluminum construction and visual finish rather than an included bearing or spacer kit. Experienced builders will treat this item as a drop-in visual and structural swap that uses standard roller post locations on compatible 4WD chassis.

Material selection and machining quality influence stiffness and how the rollers behave under contact. Aluminum rollers will perform differently than plastic or composite rollers when struck or run against guide walls, and may show different wear patterns. Check axle diameter, spacer arrangements, and whether extra washers or bearings are required before fitting to your car.

Installation tips: confirm there is adequate clearance on your chassis and that your roller mount screw length suits the thicker roller profile. If you already use bearings or slim spacers elsewhere, test for lateral play after mounting and secure the assembly with correct fasteners to prevent unwanted rotation or contact with nearby parts.
