These Traxxas Metal Differential Ring and Pinion Gear serve as a metal replacement for worn or damaged plastic differential internals, restoring reliable power transfer and reducing drivetrain play. They suit hobbyists repairing a damaged diff or anyone who wants a stronger gear set for regular driving and bashing.
Metal construction improves wear resistance compared with stock plastic gears and helps the differential handle sustained loads without premature wear. As a direct replacement ring and pinion set, installation returns the diff to solid, predictable operation so you can get back on the trail or track with confidence.
Buy Shims!
Grab some RC18T shims, seriously. I got the Team Associated part #21141 and it makes these last at least twice as long, maybe more, haven't had to replace any since adding them. Traxxas really should be including shims or at least offering them. Huge improvement for sure. The gears themselves are pretty decent.
