GPM Racing 20CRMNTI Steel + 7075 Alloy 51T Center Complete Differential for Traxxas 1/8 4WD Sledge Monster Truck-95076-4 (SLE51S)

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.
