Associated 81007 Diff / Differential Pinion Gear 10T V2 RC8T3 RC8T3e

This is the genuine Associated 81007 differential pinion gear, a 10-tooth version 2 gear built for the RC8T3 and RC8T3e truggies. The pinion gear meshes with the ring gear inside your differential, and its tooth count directly affects the internal gear ratio of your diff, which plays into how power is delivered through the drivetrain.

This version 2 gear reflects Associated's updated internal differential design, so it's the correct spec to run if you're maintaining a current-generation diff rather than trying to make an older gear work. A worn or chipped pinion gear can cause rough diff action, unusual noise, or inconsistent power delivery, so replacing it restores smooth, reliable differential operation.

This pinion gear is a direct-fit replacement engineered to Associated's factory tolerances, making it a straightforward part of routine differential maintenance for your RC8T3 or RC8T3e.
