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

Low-profile M4WD-32/PK pink 19mm ringless rollers

These 19mm ringless aluminum ball race rollers feature a machined shell and a reduced outer profile suited to experienced Tamiya Mini 4WD builders. The pink anodized finish gives a coordinated look for show or matched builds while the ringless layout lowers contact area and overall width.

The construction uses a ball-seating arrangement inside an aluminum housing; installers should align the rollers carefully on standard Mini 4WD posts and check for interference with side stays or stabilisers. Use rivets or low-profile screws with thin washers to secure the rollers without compressing the ball seating.

Fitment notes: these rollers are sized for chassis that accept 19mm diameter roller parts and are intended as replacement or aesthetic rollers rather than drivetrain upgrades. Confirm post diameter and clearance before fitting to ensure proper rotation and chassis clearance.
