Precision 18-19mm Double Roller Upgrade M4WD-36/PK Pink Spare Set by 3Racing  [M4WD-36/PK]

Technical notes for M4WD-36/PK double rollers, 18-19mm pink

The M4WD-36/PK parts are supplied as machined aluminium double rollers in the 18-19mm band with a pink finish. They are intended as aftermarket replacement rollers for 1/32 Mini 4WD platforms and focus on dimensional consistency and predictable wear rather than decorative claims.

From an installation viewpoint the twin-roller geometry shifts contact lines relative to single rollers; confirm axial clearance, mounting angle and spacer stack on your roller stay before final assembly. The items are aluminium rollers only, so fastener length and spacer thickness must be selected to suit the host stay. Avoid excessive clamp force which can deform slim plastic stays and change roll behaviour.

For maintenance or tuning, aluminium rollers provide stable wear characteristics and a precise outer diameter control compared with many molded plastics. Do not assume bearings or internal components are present unless explicitly listed by the supplier.
