The First Gear is the LEAST LIKELY to fail.
Replacing it with a metal gear makes about as much sense as putting titanium lugnuts on your truck.
The factory 7R gearboxes are best gearboxes to use.
-If you want to be proactive consider buying spare factory gears or buy an entire spare gearbox to have every gear set on hand (links below).
To Avoid Broken Gears:
-Use an ESC/soft start setup for smooth starts
-Avoid rough and bumpy terrain which cause torque spikes
-Never add rear rubber traction which can also overheat motors and increase the risk of a roll over
-Inspect gearboxes to ensure there is grease on the gear posts especially on the smallest first gear
