About This Wheel

When you hold a KNOX face-to-face, the first thing you notice is how deliberate the spoke geometry is β€” 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.

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-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.

About the GLOSS BLACK MILLED Finish

KG1 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 β€” 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.

About KG1 Forged

KG1 Forged produces wheels distributed nationally through trusted vendor channels. Catalogs are stocked, MAP-pricing is enforced, and warranty coverage is honored at the manufacturer level.

Questions We Get

Will this fit my truck?

This wheel is spec'd at 8x180 bolt pattern with a -44mm offset, which fits a wide range of Chevrolet Silverado 2500 HD, Silverado 3500 HD, GMC Sierra 2500 HD, and Sierra 3500 HD models from 2011 through 2027 depending on trim. That said, always confirm your specific year, model, and trim against the fitment guide before ordering β€” hub bore, brake caliper clearance, and suspension lift height can all affect final compatibility.

Do lug nuts come included?

Lug nuts are not included with the wheel. For an 8x180 application on these GM HD trucks, you'll want to verify seat type β€” 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.

Can I finance a set?

Yes, financing is available through multiple options including Acima, Affirm, and Synchrony Car Care, so you can spread the cost of a full set across manageable payments. Approval processes vary by lender and are handled at checkout β€” applying doesn't require a hard credit pull with all options, though terms differ.
