Data check: the bolt pattern and center bore on this page have not yet been confirmed by a second independent source. Measure your hub or ask us before ordering. How we verify
| Configuration | Wheel Size & Offset |
|---|---|
| Factory (OE) | 18x9J ET30 |
| Flush Fitment | 18x9.5J at ET12 offset |

Use these two references before ordering: the left diagram shows where each spec (PCD, center bore, offset, width and diameter) is measured on the wheel; the right diagram shows how positive, zero and negative offset shift the wheel face relative to the hub centerline.


Off-road platforms put real, repeated impact loads through the wheel that street-only vehicles never see, so the factory strength margin on the Hennessey VelociRaptor 500 Bronco isn't a formality — it's load-bearing in a literal sense. Forging matches that margin at a lower rotational weight than an equivalent cast wheel, which matters both on the trail and on the highway miles between trailheads.
The Hennessey VelociRaptor 500 Bronco ships from the factory on a 6x139.7 bolt pattern with a 93.1mm center bore and a 18x9J ET30 wheel. Our flush reference for the Hennessey VelociRaptor 500 Bronco is 18x9.5J ET12.; our maximum aggressive reference is 20x10J ET0. — beyond that, expect clearance issues against the fender liner without further modification.
The Hennessey VelociRaptor 500 Bronco ships from the factory on 6x139.7 bolt pattern wheels with a 93.1mm center bore. The stock wheel size is 18x9J ET30, offering a balanced ride that suits most owners without any rubbing or clearance concerns.
Why the factory spec works for most owners:
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Hennessey VelociRaptor 500 Bronco (2023) we drill the 6x139.7 pattern and cut the centre bore to 93.1mm on our own CNC line, so the wheel hub-centres on the car with no spacer rings, in whatever diameter, width and offset you specify.
Converting these ET figures to backspacing? Use the wheel offset and backspacing calculator.
The figures on this page are part of our open wheel fitment dataset — 10,093 vehicles, free to download, CC BY 4.0.
Backspacing ≈ width/2 + ET/25.4 + 0.5 in. "Inward" means closer to the suspension; "outward" means closer to the fender lip.
| Setup | Size | ET | Backspacing | Inward vs OE | Outward vs OE |
|---|---|---|---|---|---|
| Factory (OE) | 18x9J | ET30 | 6.18 in (157 mm) | — | — |
| Flush | 18x9.5J | ET12 | 5.72 in (145 mm) | −12 mm | +24 mm |
| Maximum | 20x10J | ET0 | 5.50 in (140 mm) | −17 mm | +43 mm |
In our database, 30 other vehicle entries from 4 makes use exactly the same 6x139.7 bolt pattern and 93.1 mm center bore. Factory wheels from these cars bolt on and center on the hub without rings; offset and width still have to be checked.
6x139.7 is used by 4.0% of the vehicle pages in our English fitment guide (258 of 6,503); 12.0% of those also use a 93.1 mm center bore.
A wheel with a center bore larger than 93.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 100.1 mm | 100.1 → 93.1 mm |
| 106.1 mm | 106.1 → 93.1 mm |
| 108.1 mm | 108.1 → 93.1 mm |
| 110.1 mm | 110.1 → 93.1 mm |
ANKUSI forged wheels are bored to exactly 93.1 mm for this vehicle, so no ring is needed.
