4x8x3 MR84ZZ / MR842RS RC Bearing for Traxxas 1/16 Slash 4X4

Bearing type options

Rubber Sealed bearings are generally better for dusty, dirty or wet RC running conditions. Metal Shielded bearings can be suitable for cleaner running conditions and lower drag applications.

Why upgrade these bearings?

This Traxxas 1/16 Slash 4X4 replacement bearing is built for owners who want a smoother, more durable RC drivetrain without guessing bearing sizes. Replacing tired stock bearings, worn bushings or gritty drivetrain bearings helps reduce drag, limit heat build-up and protect shafts, hubs, differentials and transmission parts from unnecessary wear. Choose rubber sealed bearings, also known as 2RS bearings, for dirty conditions, wet grass, loose dust and general bashing where extra seal protection matters. Choose metal shielded bearings, also known as ZZ bearings, for cleaner running conditions where low drag and free drivetrain feel are the priority. These replacement RC bearings are suitable for Slash bashing, club racing, routine servicing and rebuilds after high-speed impacts. For Maxx Slash models, check the exact product title and bearing size table before ordering so the kit matches your specific version.
