TRAXXAS E-REVO Steel Differential Spider Gears by GPM ER1200S/G2  [ER1200S/G2]

Steel Spider Gears for TRAXXAS E-REVO

These steel differential spider gears are an RC-scale aftermarket replacement designed for TRAXXAS E-REVO platforms, supplied under GPM part ER1200S/G2. The set replaces the stock alloy or plastic spider gears with hardened steel components intended to reduce wear in demanding 4WD driving and high-torque setups.

Installation is straightforward for hobbyists familiar with differential teardown: remove the diff cover, extract the gear assembly, swap the spider gears, check gear mesh and clearances, then reassemble with proper diff fluid for your tuning goals. No special tools are included or required beyond common hobby tools.

From a tuning perspective, steel spider gears are a durability upgrade rather than a dramatic handling mod. They help maintain consistent gear engagement under heavy loads, useful when running stronger motors or aggressive gearing. Expect longer service life and more predictable diff behavior during high-traction runs.
