Aluminum center differential

Traxxas Slash 4X4 BL-2s · 68154-4

This installs a complete aluminum-carrier center differential, which lets the front and rear axles turn at different speeds. Choose it when you want to tune how drive is shared between the axles using differential oil, checking whether it replaces a slipper or an existing differential on your truck.

6780Aluminum center differential with 54T 32-pitch steel spur1

Traxxas lists this package for the stated vehicle configuration. Check previously fitted upgrades and modifications before ordering.

Installation notes

  • One 6780 assembly includes an aluminum carrier, 54T 32-pitch steel spur and sealed differential filled with 1-million-weight silicone oil. Use a compatible 32-pitch motor pinion.
  • Check the installed equipment before ordering. Some factory Slash 4X4 configurations already have composite center differential 6814; on those vehicles this replaces that differential rather than a slipper.
  • Keep 6780 and 6780A identities separate; their listed contents and fill descriptions differ.
  • Set gear mesh and check center-drive and motor clearance. A center differential redistributes drive between axles and needs fluid maintenance. Retain the motor and ESC voltage limits.
