The items I ordered were OEM parts. If alternatives are available they are always offered. The reason I continue to use Jacks Small Engines for my equipment needs is that they offer consistently high quality, hassle free service. I find the part number(s) I need from my operator/ service manuals, compare them to the parts look-up feature on the website for verification and place my order.Email notifications, secure packaging and prompt delivery follow almost automatically. If you are tired of receiving unidentified parts in a torn envelope you should give these guys an opportunity.
