Ordered flishrc cobra. Communication was great. Ordered larger batteries but they were the wrong size. Olly shipped the right batteries and gave a refund for the difference I paid. Couldn't ask for more. Thanks for the help with the order.

The seller knew I was after one and very kindly informed me when they came back into stock so now have a Flywing Bell 206. Fantastic bit of kit. Well worth the wait.

About this product
Centre complete differential for Sledge
This is a fully assembled RC-scale centre differential designed for the TRAXXAS 1/8 4WD Sledge Monster Truck chassis. The unit combines 20CrMnTi steel with 7075 aerospace-grade aluminium and a 51T straight-cut main gear to improve durability and maintain driveline precision under high loads typical of large-scale off-road use.
The assembly includes 4140 carbon steel cross shafts and rubber-shielded ball bearings to simplify installation and ensure efficient power transfer. Note that differential oil is not included and must be added separately following TRAXXAS service guidance; this component replaces factory part number 9585.
For installation, verify fitment with the Sledge drivetrain before final assembly, use medium-strength threadlocker on fasteners to prevent loosening under vibration, and confirm bearing seating and gear mesh during initial run-in. This part is an aftermarket RC accessory intended to support more demanding driving conditions and longer service intervals compared to standard factory components.

- Center Complete Differential – 1pcs
Original Name / Part No:
9585

Does this replace a factory part number?

Any special installation recommendations?
