These double rollers are an aftermarket replacement produced by 3Racing for 1/32-scale Mini 4WD models. Machined from anodized aluminum, the assembly provides a metal alternative to standard plastic rollers and focuses on improved durability and stable dimensions without changing drivetrain geometry.
Fitting is done with common roller posts and the mounting methods used on Tamiya-compatible Mini 4WD chassis. The anodized finish and material are the main selling points, making this part useful for hobbyists restoring models or swapping out worn OEM plastic rollers.
This editorial does not include precise dimensions or spec sheets. Verify roller post type and clearance on your chassis prior to purchase.
