TRAXXAS SLEDGE MONSTER TRUCK 20crmnti Steel + 7075 Alloy 52T Center Complete Differential by GPM SLE52S  [SLE52S]

Center differential upgrade for SLEDGE

This GPM SLE52S center complete differential is a ready-to-fit RC-scale replacement intended for the TRAXXAS 1/8 4WD SLEDGE MONSTER TRUCK platform. The assembly pairs a 52T straight-cut main gear with hardened 20CrMnTi steel and 7075 aerospace-grade aluminium housings to improve component life under heavy load, while shipped fully assembled for faster installation.

Key mechanical notes: the main 52T gear uses a 1.0 module straight-cut profile for predictable meshing, cross shafts are specified as 4140 carbon steel for effective torque transfer, and rubber-sealed bearings are included to simplify fitment. The unit replaces factory part number #9585 and does not include differential oil, which must be supplied and filled separately following the vehicle manufacturer’s guidance.

Installation and service guidance: the differential arrives pre-assembled, verify fitment before final tightening, and it is recommended to use medium-strength screw glue on external fasteners to reduce the risk of loosening during running. For differential fluid type and fill procedure, consult the TRAXXAS manual for the correct viscosity and volume.

For builders focused on drivetrain durability and consistent center behavior, this SLE52S assembly offers a direct, material-focused upgrade path for the specified TRAXXAS Sledge platform while preserving serviceability and adjustability.
