17mm ringless aluminium ball rollers M4WD-31/PK

These 17mm aluminium ball rollers suit 1/32 Mini 4WD chassis, using a ringless ball layout to reduce the contact profile. The anodised cups offer improved surface hardness compared with painted parts, making them suitable for enthusiasts who want a clean machined ride surface.

Before fitting, confirm the roller boss size and mounting hardware on your chassis. They are compatible with standard 17mm posts and common spacer and screw arrangements employed on MA, MS, AR, FM-A, VS and Super-II builds. Because they are light spare components, check spacer thickness and screw engagement to avoid contact with stabilisers or side stays.

Care advice: inspect cup seating and the ball seat area periodically for wear, and verify screw torque. For stored cars, remove exposed metal rollers or apply a light protective coating to slow oxidation.
