Traxxas Cup RC Drive Cup - 8551

The Traxxas TRX8551 drive cup is a direct-fit replacement component designed for use exclusively with the Traxxas #8550 driveshaft assembly. This RC driveshaft component transfers drive from the differential or transmission output to the axle, and it is a critical part of the drivetrain on the compatible Traxxas model. If your existing drive cup is cracked, chipped, or worn, replacing it with this genuine Traxxas spare part restores correct drivetrain function. Note that this drive cup must only be used with the Traxxas #8550 driveshaft — it is not interchangeable with other driveshaft assemblies.
