Model number: TRA2072X
Traxxas Metal Gear Set for 2075 High Torque Servos restores the performance of the 2075X metal gear servo. The gears may also upgrade 2070, 2075, or 2075R servos if you swap all gears. Lithium grease comes with the set, but bearings are not included.
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.
