Traxxas TRA7778 Pinion Gear Rear Differential X-Maxx

Traxxas TRA7778 Pinion Gear Rear Differential X-Maxx

This is a genuine Traxxas rear differential pinion gear for the X-Maxx. The pinion drives the differential ring gear, delivering the truck's power to the rear axle through every launch and jump.

Replacing a worn pinion restores smooth, quiet operation and keeps the rear drivetrain running exactly as Traxxas designed.
