Mini 4WD Aesthetic Ringless Roller 19mm - M4WD-32/PK by 3Racing  [M4WD-32/PK]

Pink 19mm ringless aluminium rollers model M4WD-32/PK

These ringless 19mm aluminium ball race rollers are presented as a machined, low-profile option for Mini 4WD enthusiasts. The design removes the outer ring to lower the running profile and minimise external contact, while the pink anodised shell is chosen for matching display builds.

Internal ball-seating in an aluminium body requires careful alignment on compatible chassis roller posts to prevent interference with side stays or stabiliser brackets. Secure using rivets or low-profile screws with thin washers to preserve free rotation and correct lateral position.

Compatibility: intended for Mini 4WD frames accepting 19mm roller diameters. These units are cosmetic or replacement rollers rather than performance drivetrain components, so confirm post size and clearance before purchase.
