About This Wheel

Pick up a GASCAN-KOB and the first thing you notice is the weight — or rather, the lack of it for a forged piece this size. The face carries a multi-spoke design with clean milled edges that give the spoke faces just enough dimension to stay interesting without going overboard. That black ring at the lip frames the whole face and creates a layered, almost two-piece look without the additional hardware. On a dark-colored Silverado or Sierra it reads aggressive and intentional. On a white or silver truck, the contrast between the matte face and the black barrel ring does real visual work. The -12mm offset pushes the face out toward the fender, which fills the wheel well on these HD trucks the way it should.

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-12mm 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 Matte Black Black Ring Finish

KG1 Forged focuses specifically on forged aluminum construction — their catalog isn't a mix of cast and forged options, it's forged-only. That narrow focus tends to produce consistent quality control. The GASCAN-KOB is engineered for fitment on heavy-duty platforms, which means the load ratings and offset tolerances are calculated for trucks that actually work, not just trucks that look like they do.

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?

The GASCAN-KOB in 20x9 with a -12mm offset and 8x180 bolt pattern is approved for a wide range of Chevrolet Silverado 2500 and 3500 HD trims from 2011 through 2027, as well as GMC Sierra 2500 and 3500 HD trims covering the same generation span. Always confirm your specific year, trim, and any lift or leveling kit before ordering — a small change in suspension setup can affect clearance at -12 offset.

Do lug nuts come included?

Lug nuts are not included with the wheel. For an 8x180 application on GM HD trucks you'll want to match the seat type and thread pitch — most of these trucks use a 14x1.5 thread with a radius or ball seat. We can point you to the correct lug kit when you're putting your order together.
