It is a grease-lubricated hub kit, meaning the bearing cavity is packed and sealed for grease service rather than an oil-bath design, and the kit includes the cone nuts needed to secure the wheel to the hub. This kit is compatible with hub part number 008-393-04, making it a straightforward match for trailers already built around that hub.\u003c\/p\u003e\u003cp\u003eBecause it is sized for 7,200 lb capacity axles, this kit suits mid-to-heavy tandem and single-axle utility, boat, and cargo trailers running 9\/16 inch stud hubs. The grease lubrication design simplifies routine maintenance compared to oil-bath hubs, since service only requires repacking rather than monitoring an oil level or seal integrity for leaks. Installers replacing worn hub hardware or servicing a hub that takes 9\/16 inch studs at a 4.75 inch pitch diameter can use this kit to restore the wheel-mounting hardware to factory-rated capacity.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Dexter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 008-393-91\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad Capacity:\u003c\/strong\u003e 7,200 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStud Size:\u003c\/strong\u003e 9\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch Diameter:\u003c\/strong\u003e 4.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLubrication Type:\u003c\/strong\u003e Grease\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Cone nuts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 49.3 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eCompatible with hub part number 008-393-04\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the load capacity of the Dexter 008-393-91 hub kit?\u003c\/strong\u003e The Dexter 008-393-91 hub kit is rated for a 7,200 pound capacity.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat stud size does this hub kit use?\u003c\/strong\u003e This kit is built for 9\/16 inch wheel studs on a 4.75 inch pitch diameter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 008-393-91 kit grease or oil lubricated?\u003c\/strong\u003e It is a grease-lubricated design, so the hub is packed and sealed for grease service rather than running as an oil bath.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the kit come with cone nuts?\u003c\/strong\u003e Yes, cone nuts are included with the Dexter 008-393-91 hub kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat hub is the 008-393-91 kit compatible with?\u003c\/strong\u003e The 008-393-91 kit is compatible with hub part number 008-393-04.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Dexter 008-393-91 hub kit weigh?\u003c\/strong\u003e The kit weighs 49.3 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size trailer axle is this hub kit suited for?\u003c\/strong\u003e Rated at 7,200 pounds capacity with 9\/16 inch studs, the 008-393-91 kit suits mid-to-heavy duty trailer axles built around that stud size and capacity.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does the pitch diameter matter when ordering this kit?\u003c\/strong\u003e The 4.75 inch pitch diameter of the 008-393-91 kit must match your existing hub so the studs and cone nuts line up correctly with the wheel bolt pattern.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this kit be used on an oil-bath hub?\u003c\/strong\u003e No, the 008-393-91 kit is designed for grease lubrication, not an oil-bath hub, so it should be matched to a hub built for grease service.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the Dexter 008-393-91 kit?\u003c\/strong\u003e The kit includes the hardware needed for a 9\/16 inch stud, 4.75 inch pitch diameter grease hub, including cone nuts, at a 7,200 pound capacity rating.\u003c\/p\u003e","brand":"Dexter","offers":[{"title":"Default Title","offer_id":48991256871131,"sku":"DEX-008-393-91","price":488.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/dexter-8-on-6.5-7.2k-hub-drum-kit-post-1999-008-393-91__30616.1747363836.500.750.jpg?v=1785329093","url":"https:\/\/www.goodvibesmarina.com\/products\/7-200-lb-trailer-hub-and-drum-kit-8-on-6-50-bolt-pattern-9-16-studs-grease-lube-mpn-008-393-91","provider":"Good Vibes Marina","version":"1.0","type":"link"}
