The Dual-Flex progressive design handles both the low-speed idle vibration common to diesels and the higher loads at cruise without needing a different mount for each condition.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon issues:\u003c\/strong\u003e The most frequent ordering mistake is confusing the DF-2207-1 with the \u003cstrong\u003eDF-2207-2\u003c\/strong\u003e. The two mounts share the same footprint and weight rating but use different stud sizes — 1\/2 in. versus 5\/8 in. — and are not interchangeable. Check the existing stud with a thread gauge or measure the wrench flats before ordering. The second common issue is selecting by engine model name rather than confirmed installation weight: an engine may fall in the DF-2207 range without its transmission, but exceed it once the full powertrain is accounted for. Always weigh or look up the combined engine-and-transmission weight before specifying the mount.\u003c\/p\u003e","brand":"BUS","offers":[{"title":"Default Title","offer_id":43563780210724,"sku":"DF2207-1","price":155.74,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/fcad74a3-710a-4140-8a75-649a0352433c.png?v=1788824004","url":"https:\/\/marisolmarine.com\/products\/bushings-inc-df-2207-1-dual-flex-marine-engine-mount","provider":"Marisol Marine Company","version":"1.0","type":"link"}
