{"product_id":"kg1-forged-knox-8-lug-8x180","title":"KG1 Forged KNOX - 8 LUG","description":"\u003cp\u003eWhen you hold a KNOX face-to-face, the first thing you notice is how deliberate the spoke geometry is — these aren't generic five-spokes stretched to fill a 12-inch width. The deep negative offset of -44mm pushes the face out aggressively, giving that flush, filled-fender look that wide-body HD trucks are built to carry. The milled pockets cut into the gloss black face catch light at sharp angles, creating a layered contrast between the raw aluminum and the dark background. On a white or silver Silverado, that contrast reads clean and purposeful. On a blacked-out Sierra, the milled edges provide just enough break to keep the wheel from disappearing into the truck's bodywork.\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\u003e20\" x 12\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBolt Pattern\u003c\/th\u003e\n\u003ctd\u003e8x180\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOffset\u003c\/th\u003e\n\u003ctd\u003eET-44mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHub Bore\u003c\/th\u003e\n\u003ctd\u003e124.30mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConstruction\u003c\/th\u003e\n\u003ctd\u003eForged\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\u003eGLOSS BLACK MILLED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer Part Number\u003c\/th\u003e\n\u003ctd\u003eKF008201288GM\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 8x180 bolt pattern, which covers a range of half-ton trucks and SUVs depending on hub bore and offset. ET-44mm 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 GLOSS BLACK MILLED Finish\u003c\/h3\u003e\u003cp\u003eKG1 Forged operates as a forged-specific brand, which means their entire manufacturing focus is on the forging process rather than splitting attention across cast or flow-formed lines. Forged construction at this diameter and width matters for HD truck applications — the material density and grain structure handle the torque loads and payload dynamics that a 2500 or 3500 series truck actually generates under real working conditions.\u003c\/p\u003e\n\u003ch3\u003eAbout KG1 Forged\u003c\/h3\u003e\u003cp\u003eKG1 Forged produces wheels distributed nationally through trusted vendor channels.

That said, always confirm your specific year, model, and trim against the fitment guide before ordering — hub bore, brake caliper clearance, and suspension lift height can all affect final compatibility.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo lug nuts come included?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eLug nuts are not included with the wheel. For an 8x180 application on these GM HD trucks, you'll want to verify seat type — most factory and aftermarket lug nuts for this bolt pattern use a 14x1.5 thread pitch with a conical or bulge-acorn seat depending on the lug nut style. We can advise on compatible hardware when you're ready to order.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I finance a set?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eYes, financing is available through multiple options including \u003cstrong\u003eAcima\u003c\/strong\u003e, \u003cstrong\u003eAffirm\u003c\/strong\u003e, and \u003cstrong\u003eSynchrony Car Care\u003c\/strong\u003e, so you can spread the cost of a full set across manageable payments.
