M4WD-49/BL precision rail guard

Compact aluminium rail guard engineered for experienced Mini 4WD builders focused on tidy, repeatable chassis setups. The black finished guard provides a stiff, lightweight replacement for worn rail trim without changing drivetrain geometry.

Designed to align with typical rail mounting locations on many Tamiya Mini 4WD platforms, the guard requires verification of hole centres and body clearance prior to final assembly. Use existing low-profile fasteners where possible and check for any contact with bumpers or shell overhang during dynamic fit checks.

Routine maintenance is low effort: clean with a soft cloth and nonabrasive cleaner and inspect mating faces for paint transfer or burrs. The part is intended for reliable service in club and practice environments but is not a mechanical performance upgrade.

Aim for hole centre tolerances within 0.5 mm when possible. A small mismatch can be accommodated with thin washers, but better alignment reduces stress on fixings.
Use low-profile countersunk or pan head screws sized to your chassis holes. Stainless or plated steel fasteners balance corrosion resistance and stiffness for general use.
Yes, it is light and adds minimal mass. However, treat it as a cosmetic/durability item; any performance impact is negligible for tuning decisions.
