3Racing M4WD-33/RE Double 8-9mm Aluminum Rollers (red)

These double aluminum rollers are a compact spare intended for experienced Mini 4WD hobbyists who maintain or restore 1/32-scale models. The set uses a double-roller arrangement in an 8-9mm diameter range and is finished in red anodizing. Material choice and surface treatment are noted to improve wear resistance compared with untreated metal rollers, while keeping mass low.

Compatibility depends on roller shaft and mounting hole clearances found on common 4WD chassis. Check axle bore diameter, spacer thickness, and any local chassis modifications before installation. The rollers are compatible with standard roller shafts and most two-piece mounting setups used on Super-II, MA, MS, AR and other performance-oriented chassis; verify clearance on non-standard or scale-style bodies.

Installation advice for experienced builders: confirm shaft alignment and lateral clearance, use light lubrication on contact surfaces where bearings are not present, and avoid overtightening fasteners that can deform the roller or mounting bracket. Inspect anodize for chips after installation and replace if structural damage appears. These rollers are intended as replacement parts or for custom setups; they are not a kit upgrade for non-performance series models.

Maintenance notes: periodic cleaning and inspection will help detect wear or play at the shaft interface. If the set uses small bearings or bushings, ensure those components meet your preferred tolerance and replace with matched parts when necessary.
