Traxxas 10287-RED Gear Cover Aluminum Red O Figuers The built-in high precision HallAluminum gear cover with a red anodized finish. The gear cover shields the spur and pinion from dirt, grit, and debris thrown up by the tires. Grit that reaches the gear mesh acts as grinding paste and will chew through a spur gear far faster than normal wear. Aluminum stands up to impacts that crack a moulded cover and leave the gears exposed. Fits: Traxxas Maxx Slash (102076 4). Direct replacement for the factory gear cover.
