About This Wheel

Pick up a DIAMONDHEAD and the first thing you notice is how the face is machined — tight, angular spoke geometry that earns its name. The diamond-cut profile catches light in hard lines rather than broad sweeps, which plays especially well in matte black because the contrast stays subtle, almost industrial. On a blacked-out F-150 or a dark-gray Expedition, this wheel disappears into the build in the best possible way. On a white or silver truck, it creates a sharp tonal break that reads intentional rather than accidental.

Fitment

This wheel runs the 6x135 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 Finish

KG1 Forged operates out of the performance wheel segment with a focus on flow-formed and fully forged construction. Their wheels are engineered to meet or exceed SAE and JWL structural standards, which matters more than marketing language when you're running a loaded F-150 or a heavy Lincoln Navigator. KG1 isn't trying to be everything to everyone — they build a focused lineup and back the fitment engineering with real data.

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 fitment-verified for a wide range of Ford and Lincoln platforms, including the F-150 (2004–2027 across most trims), Ford Expedition (2003–2024), Lincoln Navigator (2003–2027), and the Lincoln Mark LT (2006–2008). All share the 6x135 bolt pattern this wheel is built around. If your specific trim isn't listed, confirm your OEM bolt pattern and hub bore before ordering.

Do lug nuts come included?

Lug nuts are not included with the wheel. For a forged wheel at this offset, you'll want conical-seat lug nuts in the correct thread pitch for your application — Ford F-150 and Expedition platforms typically run 14x1.5 thread. Using the wrong seat style can cause improper torque retention, so don't reuse factory lugs without verifying compatibility.
