About This Wheel
Pick one up and the first thing you notice is how the mass is distributed β forged construction pulls weight out of the barrel without thinning the spokes where stress actually lives. The OKTO runs eight spokes in a clean, symmetrical layout that reads as purposeful rather than busy. At a 0mm offset, the face sits flush and assertive in the wheel well, which suits the wide-body stance of the 2500HD and 3500HD trucks this wheel is approved for. The milled cuts across the spoke faces catch directional light differently than the gloss black surround, giving the wheel a two-tone contrast that holds up at highway speed and in a static show stance equally well. Darker truck colors β midnight blue, black, dark gray β let the milled highlights do the heavy lifting.

Fitment
This wheel runs the 8x180 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.
About the GLOSS BLACK MILLED Finish
KG1 Forged focuses specifically on flow-formed and fully forged aluminum wheels for the truck and SUV market. Their forged lineup goes through a die-forging process that increases grain density compared to cast alternatives, which matters on heavy-duty applications where load ratings and long-term durability are real concerns. They're not the oldest name in the space, but their engineering approach is straightforward and verifiable.

Questions We Get
Will this fit my truck?
This wheel is spec'd at 20x9 with a 0mm offset and an 8x180 bolt pattern, which is correct for a wide range of Chevrolet Silverado 2500HD and 3500HD trucks from 2011 through 2027, as well as GMC Sierra 2500HD and 3500HD models across the same general span. That said, always verify your specific trim and model year before ordering β hub bore, brake caliper clearance, and any factory lift or leveling kit can all affect final fitment.
Do lug nuts come included?
Lug nuts are not included with the wheel. The 8x180 platform uses a specific seat type and shank length that varies by truck generation, so it's worth confirming the correct lug nut spec for your year and trim rather than reusing whatever came off your factory wheels.
Can I finance a set?
Yes β financing options are available through Acima, Affirm, and Synchrony Car Care, giving you flexibility on how you pay for a set. Terms and approval criteria vary by lender, so it's worth checking which option works best for your situation at checkout.
