TRAXXAS E-REVO Steel Differential Gear Set ER1200S by GPM  [ER1200S]

Replacement steel gears for E-REVO differentials

This gear kit is a precision RC differential internals set made for TRAXXAS E-REVO platforms. The hardened steel components feature a black finish to give a stable contact surface under load and steady rotational feel inside the diff case. It is intended as a direct swap for the stock internal gears where the listed compatibility applies.

Installation follows routine diff service steps: remove the diff cover, take out the original gears, check bearings and pinion/spur engagement, then fit the steel output and spider gears. Verify gear mesh and clearance before final assembly, and re-use or replace O-rings as needed to maintain diff sealing. Use a suitable differential grease and confirm smooth rotation through full suspension travel.

Tuning notes: steel internals alter wear patterns and heat transfer versus softer alloys or plastics, so inspect backlash and bearing condition after the first few runs. Maintain consistent lubrication and avoid over-tightening housing screws since that can change gear mesh.

This set suits hobby-level maintenance and upgrades on listed 1/10 4WD platforms, providing a metal option for diff internals where compatibility is stated.
