Technical overview of M4WD-35/LB double aluminium rollers

The M4WD-35/LB is a compact paired-roller assembly designed for Mini 4WD use, featuring machined aluminium bodies and a light blue anodized surface. The carrier mounts two rollers in close spacing to minimise lateral profile while maintaining secure mounting alignment.

Manufacture uses CNC-style machining processes to produce matched roller shells mounted on a single unit. Installers should confirm bracket hole spacing, axle diameter and stack height to ensure the rollers clear stabilisers and guide pins. The specified diameter range of 16-17mm targets low-profile applications where minimal clearance is required.

Technical integration notes include checking axial play, spacer thickness and bearing type. The rollers are compatible with many standard roller brackets and common bearing assemblies, but verify shaft and nut dimensions prior to final torque. The anodized coating is for surface protection and cosmetics rather than structural performance.

Use this component primarily as a replacement or aesthetic upgrade. For race tuning, evaluate roller stack geometry and mass distribution as part of the overall setup process.

What mounting tolerances should I verify

Verify bracket hole spacing, axle diameter and available clearance to stabilisers. Ensure spacer thickness yields correct lateral and axial positioning.

Which bearing types are recommended

Use low-friction bearings sized to your shaft for best rolling performance, or high-quality bushings if preferred for display builds. Bearings are not specified as included.

How to set correct stack height

Measure from bracket face to stabiliser and adjust spacer thickness so the roller face aligns without binding. Small trial fits reduce the risk of rubbing under load.

Is the anodize suitable for high-wear locations

Anodize adds surface hardness and corrosion resistance but will show wear at constant contact points. For high-wear racing positions consider protecting contact edges or swapping to dedicated race rollers.

Recommended maintenance schedule

Inspect rollers and bearings before and after sessions, clean contact faces and check for axial play. Replace any components with measurable deformation or excessive wear to maintain predictable handling.
