{"product_id":"us-mag-1pc-u120-roadster-5x120","title":"US Mag 1PC U120 ROADSTER","description":"\u003cp\u003eThe Roadster face runs a set of broad, tapered spokes that fan outward from a compact hub — a silhouette US Mag has been refining for decades on street machines and show floors alike. At 18 inches the proportions stay honest: the spokes are thick enough to read as structural, not decorative. That 1mm offset places the face almost flush with the hub centerline, so you get a pronounced lip without pushing the wheel dangerously outboard. Gunmetal here reads as a mid-tone charcoal with just enough metallic grain to catch overhead light differently than flat dark finishes. It layers well against black, dark silver, and deep blue body panels, and it doesn't fight burgundy or oxblood paint the way a high-polish wheel often does. On a square-body or G-body application especially, this wheel lands exactly where it should visually.\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\u003e18\" x 8\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBolt Pattern\u003c\/th\u003e\n\u003ctd\u003e5x120\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOffset\u003c\/th\u003e\n\u003ctd\u003eET+1mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBackspacing\u003c\/th\u003e\n\u003ctd\u003e4.54\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHub Bore\u003c\/th\u003e\n\u003ctd\u003e72.56mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLoad Rating\u003c\/th\u003e\n\u003ctd\u003e1900 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\u003eGUNMETAL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer Part Number\u003c\/th\u003e\n\u003ctd\u003eU12018806145\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 5x120 bolt pattern, which covers a range of half-ton trucks and SUVs depending on hub bore and offset. ET+1mm 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 GUNMETAL Finish\u003c\/h3\u003e\u003cp\u003eUS Mag has been producing American-styled cast wheels since 1965, and the U120 Roadster sits squarely in that heritage lineup. The brand built its reputation on the muscle car and hot rod market and has stayed consistent there rather than chasing trends. Construction is cast aluminum, which keeps the price accessible while delivering adequate strength for street and occasional track use.\u003c\/p\u003e\n\u003ch3\u003eAbout US Mag 1PC\u003c\/h3\u003e\u003cp\u003eUS Mag 1PC produces wheels distributed nationally through trusted vendor channels.

Always verify your vehicle's bolt pattern, hub bore, and clearance requirements before ordering, since offset and width tolerance vary significantly by application.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo lug nuts come included?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eLug nuts are not included with this wheel. US Mag wheels typically require a seat type that matches your vehicle's factory lug specification — conical, ball, or mag-style seat — so it's worth confirming that before purchasing hardware separately. We can help you identify the correct lug nut when you order.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I finance a set?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eYes, financing is available through several options including \u003cstrong\u003eAcima\u003c\/strong\u003e, \u003cstrong\u003eAffirm\u003c\/strong\u003e, and \u003cstrong\u003eSynchrony Car Care\u003c\/strong\u003e.
