{"product_id":"traxxas-3691-gray-magnum-272-gray-gearbox-halves","title":"Traxxas 3691-GRAY Magnum 272 Gray Gearbox Halves","description":"\u003cp\u003eThe Traxxas 3691-GRAY is a left and right pair of gearbox halves for the Magnum 272 transmission, with the idler gear shaft included.\u003c\/p\u003e\u003cp\u003eThe gearbox halves form the housing that holds the whole transmission together, locating the shafts, supporting the bearings, and setting the gear mesh. Once a half is cracked or a screw boss has stripped, the mesh no longer holds true and wear accelerates straight into the gears. Replacing the housing at that point is considerably cheaper than replacing a chewed-up gearset afterwards.\u003c\/p\u003e\u003cp\u003eTypical reasons to fit these are impact damage that has split a case, stripped bosses that no longer clamp the halves together, or a planned rebuild where it makes sense to start with a fresh housing rather than reuse a fatigued one. The included idler gear shaft covers one of the internal parts most likely to be worn by the time the housing needs attention.\u003c\/p\u003e\u003cp\u003eFitment note: these fit the Magnum 272 transmission only and will not fit the Magnum 272R. The two units are not interchangeable, so confirm which transmission your vehicle uses before ordering.\u003c\/p\u003e\u003cp\u003eSupplied as a left and right pair.
