Fitment

This wheel runs the 8x170 bolt pattern, which covers a range of half-ton trucks and SUVs depending on hub bore and offset. ET-24mm 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 POLISHED Finish

KG1 Forged operates as a specialty forged-wheel brand with a focused catalog — they're not trying to cover every price point. Their wheels are flow-formed or fully forged depending on the model, and the SEISMIC-KC sits in the forged tier. That means tighter grain structure, better strength-to-weight ratio, and dimensional consistency that cast wheels typically can't match at this diameter.

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 SEISMIC-KC in this configuration is spec'd for 8x170 bolt pattern fitment, which covers Ford F-250 and F-350 Super Duty trucks from the 1999 model year through current production, as well as the Ford Excursion from 2000 to 2005. Always confirm your specific cab, bed, and suspension setup before ordering, since lift height and brake caliper clearance can affect final fitment.

Do lug nuts come included?

Lug nuts are not included with the wheel. Ford 8x170 trucks typically require a 14x1.5 thread pitch lug nut, and because the SEISMIC-KC is a forged wheel with a specific seat angle, you'll want conical lug nuts matched to the wheel's seat type. We can spec the correct hardware when you place your order.

Can I finance a set?

Yes — we offer financing through Acima, Affirm, and Synchrony Car Care, so you have a few different structures to choose from depending on your preference. Acima works as a lease-to-own option that doesn't rely solely on traditional credit scoring, while Affirm offers installment loans with transparent terms. Apply at checkout and you'll typically get a decision in seconds.
