Replacement Mini 4WD Double 8-9mm Aluminum Rollers M4WD-33/RE (red) by 3Racing  [M4WD-33/RE]

Red anodized 8-9mm double rollers for 1/32 Mini 4WD

These double aluminum rollers are a compact option for hobbyists working on 1/32 Mini 4WD cars. The paired 8-9mm rollers feature red anodizing to improve surface hardness versus untreated metal while keeping overall rotating mass low for performance setups.

Fit depends on your chassis roller shaft and mounting clearances. Measure axle bore, spacer stacks and any local chassis mods before installation. They are compatible with typical roller shafts and two-piece mounting systems used on Super-II, MA, MS, AR and other performance chassis; check fit on unusual or scale-oriented bodies.

Installation guidance for experienced tuners: verify shaft alignment and lateral play, use light lubrication if bearings are absent, and avoid over-tightening fasteners that may deform the roller or mount. Check the anodize after fitting and replace any roller with visible damage. These are intended as replacement or custom setup components rather than generic kit upgrades.

Maintenance advice: regular cleaning and inspection will reveal burrs, looseness or anodize wear. If using bearings or bushings, match their tolerances to your setup and refresh them when performance drops.
