Mini 4WD Low-Profile 17mm Ringless Rollers M4WD-31/PK Pink by 3Racing  [M4WD-31/PK]

M4WD-31/PK 17mm ringless aluminium rollers in pink

These 17mm aluminium ball race rollers are produced for 1/32 scale Mini 4WD applications and feature ringless ball assembly for a reduced running face. The anodised aluminium cups provide a tougher surface finish and a clean machined contact edge that suits tight clearance setups.

Verify fitment against the roller boss diameter and mounting hardware on your Mini 4WD chassis. The rollers fit standard 17mm posts and the common spacer and screw configurations used on MA, MS, AR, FM-A, VS and Super-II platforms. As lightweight spares, consider spacer and screw choices carefully to prevent any interference with stabilisers or side stays.

Maintenance advice: inspect the seating area for wear and check screw torque periodically. For display or long term storage, protect exposed metal surfaces to guard against oxidation.
