These double aluminium rollers are offered by 3Racing as an aftermarket assembly for 1/32-scale Mini 4WD cars. CNC-style machining and an anodised red surface give a metal alternative to the usual plastic rollers, prioritising wear resistance and consistent geometry rather than changing drivetrain behaviour.
They mount using standard roller posts and the common mounting methods found in Tamiya-compatible Mini 4WD builds. Hobbyists and collectors will value the finish and long-term serviceability when replacing aged or brittle plastic rollers.
No precise dimensions are listed here; confirm roller post compatibility and clearance with your chassis before ordering.
