Traxxas Ring & Pinion Machined Spiral Cut Rear RC Differential Gear - 6879R

The Traxxas TRX6879R is a machined spiral-cut ring gear and pinion gear set for the rear differential, designed as a direct-fit replacement for a wide range of Traxxas Slash, Stampede, Rustler, and Bandit models. Spiral-cut machining gives these differential gears smoother engagement and quieter operation compared to standard straight-cut gears, making this a worthwhile upgrade when rebuilding a worn rear diff. This is a genuine Traxxas spare part, so fitment across compatible models is precise and straightforward.
