Overview
The Hot Racing Steel 54T Main Spur Gear is a hardened-steel direct replacement for the Traxxas TRA7591 plastic spur gear used on the LaTrax Rally. CNC-machined from #45 hardened steel, this 0.5 module 54-tooth spur eliminates the stripped teeth and gear failures that plague the stock plastic gear — especially when paired with high-output brushed motors or brushless upgrades.
The 54-tooth count is a popular choice for drivers seeking slightly higher top-end speed than the 60T, while still benefiting from the full strength and longevity of a steel spur gear.

Usage Notes
Verify gear mesh after installation — there should be a small amount of backlash with no binding. Apply light grease to gear teeth. Re-check pinion mesh after the first run as the steel spur seats in.
