TRAXXAS E-REVO Steel Output and Spider Gears ER1200S by GPM  [ER1200S]

Durable steel diff gears for E-REVO

This is a hardened steel differential gear set designed for TRAXXAS E-REVO applications. The black-finish steel offers a stable contact face under load and delivers consistent rotational behaviour inside the diff shell. It is intended as a direct internal gear replacement for the listed compatible platforms.

Fitting uses standard diff service practices: remove the diff cover, take out the factory gears, inspect bearings and mating gears, then install the steel output and spider gears. Set gear mesh and clearances before closing the case, and re-use or change the supplied O-rings where needed to preserve sealing. Use the appropriate differential grease and confirm smooth rotation through suspension travel.

Setup advice: steel internals will affect wear and heat dispersion compared with softer materials. Keep an eye on backlash and bearing condition after initial runs, keep lubrication regular, and avoid over-tightening the case screws to prevent mesh distortion.

Suitable for hobby technicians seeking a metal option for diff internals on compatible 1/10 4WD platforms, useful for durability and serviceability upgrades.
