{"product_id":"traxxas-3691-slgry-slate-gray-gearbox-halves","title":"Traxxas 3691-SLGRY Slate Gray Gearbox Halves","description":"\u003cp\u003eThe Traxxas 3691-SLGRY is a left and right pair of gearbox halves for the Magnum 272 transmission, supplied with the idler gear shaft.\u003c\/p\u003e\u003cp\u003eThese halves make up the transmission housing. They locate the shafts, carry the bearings, and hold the gear mesh in correct alignment. A cracked half or a stripped screw boss lets that alignment drift, and once the mesh is off the gears wear rapidly. Catching it and replacing the housing is a far smaller job, and a far smaller bill, than replacing a destroyed gearset.\u003c\/p\u003e\u003cp\u003eCommon reasons to need these include a case split by a hard impact, screw bosses that no longer hold the halves clamped together, or a rebuild where starting with a fresh housing makes more sense than reusing a fatigued one. The idler gear shaft is included, covering a component that typically shows wear by the time the housing does.\u003c\/p\u003e\u003cp\u003eFitment note: these fit the Magnum 272 transmission and will not fit the Magnum 272R transmission. The two are not interchangeable, so check which unit your vehicle runs before ordering.\u003c\/p\u003e\u003cp\u003eSupplied as a left and right pair.
