Model number: TRA2072X
Traxxas Metal Gear Set for 2075 High Torque Servos replaces the gears in your 2075X servo. The set includes lithium grease, and its gears may upgrade 2070, 2075, or 2075R servos if you swap all gears. Bearings are not included and must be bought separately.
Factory should use these
I honestly dont get why Traxxas doesnt just include metal gears in their servos from the start, it cant cost them much to do so. Anyway, I busted my servo when I crashed into concrete w/ the steering wheel, and these gears made it way stronger. For fun, I tried breaking it again, but the gears held up perfectly. If your servo shows any wear or breaks, def order these.
