The Tamiya Mini 4WD Aluminum Rail Guard in red, model number M4WD-49/RE, is a practical replacement part that strengthens chassis stability and longevity for Mini 4WD cars. This guard is aimed at hobbyists who want a durable, low-mass solution to protect common impact points on the car.

Design and chassis fitment

The rail guard is made to mate cleanly with many Mini 4WD chassis layouts and keeps additional mass to a minimum so top speed and cornering remain largely unaffected. It fits popular platforms including MS, MA, and AR, giving racers flexible installation options.

On track benefits

During competitive runs the rail guard helps limit damage from side impacts and heavy landings, helping cars stay on line and reducing repair time between heats. The red finish also makes it simple to spot on the pit bench.
