TRAXXAS Sledge Center Differential 51T Straight-Cut Gear Upgrade - SLE51S by GPM  [SLE51S]

Heavy-duty centre differential for Sledge

This fully assembled RC centre differential is made for the TRAXXAS 1/8 4WD Sledge Monster Truck chassis. It pairs 20CrMnTi steel with 7075 aerospace-grade aluminium and a 51T straight-cut main gear to increase strength and maintain driveline precision under the high loads common to large-scale off-road rigs.

The assembly includes 4140 carbon steel cross shafts and rubber-shielded ball bearings to simplify fitting and ensure efficient power transfer. Differential oil is not supplied and should be added separately following TRAXXAS service guidance; this unit replaces factory part number 9585.

For installation, verify fitment with the Sledge drivetrain before final assembly, use a medium-strength threadlocker on fasteners to prevent loosening under vibration, and confirm bearing seating and gear mesh during the initial run-in. This aftermarket RC accessory targets hobbyists who need improved durability and longer service intervals compared with stock components.

This centre differential is a direct replacement for the factory unit on the TRAXXAS Sledge, offering stronger materials and a complete assembled package for hobbyists seeking a robust drivetrain upgrade for large-scale off-road use.
