{"product_id":"kmc-km724-impact-ol-black","title":"KMC KM724 IMPACT OL — Black","description":"\u003cp\u003ePick one up and the first thing you notice is how solid the casting feels — no flex, no thin spots around the spokes. The Impact OL runs a multi-spoke face with a slight outward relief that gives the wheel depth without going overboard on complexity. At 17 inches it sits proportionally well under factory fenders and mild lifts alike. The \u003cstrong\u003eBlack\u003c\/strong\u003e finish absorbs direct light rather than bouncing it around, which keeps the wheel from competing with bodywork — it anchors the look instead. That quality pairs naturally with white, silver, charcoal, and darker body colors across trucks and full-size SUVs. The 6x120 bolt pattern targets GM full-size platforms specifically, and the 0mm offset keeps the face flush with the fender line rather than tucking it inward.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eDiameter x Width\u003c\/th\u003e\n\u003ctd\u003e17\" x 8.5\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBolt Pattern\u003c\/th\u003e\n\u003ctd\u003e6x120\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOffset\u003c\/th\u003e\n\u003ctd\u003eET+0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBackspacing\u003c\/th\u003e\n\u003ctd\u003e4.75\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHub Bore\u003c\/th\u003e\n\u003ctd\u003e66.90mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLoad Rating\u003c\/th\u003e\n\u003ctd\u003e2500 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConstruction\u003c\/th\u003e\n\u003ctd\u003eCast\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eAluminum alloy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eBLACK\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer Part Number\u003c\/th\u003e\n\u003ctd\u003eKM72478577700US\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eThis wheel runs the 6x120 bolt pattern, which covers a range of half-ton trucks and SUVs depending on hub bore and offset. ET+0mm offset is typical for stock-height fitments; leveled and lifted trucks may want different offset\/backspacing combinations to clear larger tires. A hub-centric ring is recommended when the wheel hub bore is larger than the vehicle hub.\u003c\/p\u003e\n\u003ch3\u003eAbout the BLACK Finish\u003c\/h3\u003e\u003cp\u003eKMC has been producing truck and off-road wheels since the late 1990s, and their casting quality control is consistent enough that we stock them with confidence. The Impact OL line sits in their value-to-performance range — not their flagship, but built to the same dimensional tolerances. If you want a dependable cast wheel without paying for a name you're just going to mud up anyway, KMC makes sense.\u003c\/p\u003e\n\u003ch3\u003eAbout KMC\u003c\/h3\u003e\u003cp\u003eKMC produces wheels distributed nationally through trusted vendor channels.

Always cross-reference your hub bore and check your trim level before ordering, since not every 6x120 application shares the same hub center diameter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo lug nuts come included?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNo, lug nuts are sold separately.
