RCG Racing 18-Series Engranaje Principal del Diferencial

Replacement was a perfect drop-in fit for my short course truck, no shimming or filing needed to get the mesh right. Spins smooth and quiet on the bench, and it's holding up fine after a few full battery packs.

My old diff gear was stripped, but this replacement dropped right in with no issues. The gear teeth mesh perfectly with the pinion, and it's held up well through a few packs on my short course truck.

My 18-series monster truck was sitting on the shelf with a stripped diff gear, but this replacement fit perfectly and brought it back to life. The hardened steel teeth feel much more durable than the stock plastic ones.
