TRX-4472R Traxxas Spur Gear, 72-Tooth (32-Pitch / 0.8 Metric Pitch)

The 4472R is a 72-tooth 32-pitch (0.8 metric pitch / 0.8 Mod) spur gear for many Traxxas vehicles. Unlike the 4472, this is a standard spur gear style — no bushing and no friction pegs required. Swapping spur gears shifts the final drive ratio — fewer teeth lean toward top speed, more teeth lean toward torque and acceleration.

What’s Included

• (1×) 72-tooth spur gear (32-pitch / 0.8 metric pitch)

Fitment Note

Fits many Traxxas vehicles using 32-pitch (0.8 metric pitch) gearing. This is not the same as the 4472 — the 4472R is a standard spur gear style requiring no bushing or friction pegs, while the 4472 uses both. Consult your vehicle’s manual or parts diagram to verify fitment before ordering.

Key Features

• 72-tooth count in 32-pitch (0.8 metric pitch) — larger tooth count favors torque and acceleration
• Smaller spur gear tooth count = higher speed; larger tooth count = more acceleration
• Standard spur gear style — no bushing or friction pegs required
• Compatible with 32-pitch pinion gears
