Why the 8x165.1 pattern matters
The 8x165.1 (8x6.5") bolt circle is the workhorse pattern behind many three-quarter and one-ton trucks, so getting the right wheel means matching load capacity, hub clearance, and the deep negative or positive offsets that dually and lifted setups demand. Ultra's eight-lug designs in this pattern are built as monoblock castings, a one-piece construction that keeps things simple and strong for towing and hauling duty. Because the offsets here run the full spread — from deep positive fronts like +129 to aggressive rear figures near -140 — pairing the correct front and rear is essential on dually applications.
Which Ultra models & finishes come in 8x165.1
Dually-specific designs lead the way. The 002FBK Modular Dually and matching 002RBK Modular Dually arrive in Gloss Black, while the 003FBM Hunter Dually wears Gloss Black with Milled Accents and the 022FU Scorpion Dually adds a Gloss Black with Diamond Cut Face. Polished fans can look at the 02P Modular Dually, and the 025SB Phantom Dually brings a Satin Black with Machined Accents look.
Beyond duallies, single-wheel eight-lug options include the 124BK Commander in Gloss Black, the 231BM Butcher in Gloss Black with Milled Accents, the bronze-lipped 236BZM Apocalypse, and the 208P Badlands in Polished. If you want to shop strictly by color, see Black Ultra wheels, Bronze Ultra wheels, Chrome Ultra wheels, or Silver Ultra wheels.
Fitment coverage & related patterns
In this eight-lug pattern, diameters run from 16-inch dually faces through 17-, 18-, and 20-inch fitments depending on the design — browse the 16" Ultra wheels, 17" Ultra wheels, 18" Ultra wheels, and 20" Ultra wheels for size-first shopping. Many of these same models also offer neighboring eight-lug circles, so if your truck actually runs a different pattern, check Ultra 8x170 wheels for late-model Ford Super Duty or Ultra 8x180 wheels for newer GM HD trucks. Half-ton and SUV owners can cross-shop the six-lug Ultra 6x135 wheels and Ultra 6x139.7 wheels, or the five-lug Ultra 5x150 wheels.
How to choose your set
Confirm your bolt pattern first, then decide between a dually and single-rear-wheel design — dually trucks need matched front and rear part numbers because the rear sits at a deep negative offset to span the wider axle. The 002FBK Modular Dually 16x6 +102 in Gloss Black pairs with the 002RBK Modular Dually 16x6 -125 in Gloss Black as one example of a front/rear set. If you're stepping up to 17-inch dually fitment, the 002RP Modular Dually 17x6.5 -140 in Gloss Black and the 022FBK Scorpion Dually 17x6.5 +129 in Gloss Black are good reference points. Choose the finish last: Gloss Black hides brake dust and trail grime, while milled and diamond-cut faces add contrast.
Frequently Asked Questions
What vehicles use the Ultra 8x165.1 bolt pattern? The 8x165.1 (8x6.5") pattern is the eight-lug fitment found on many heavy-duty trucks, including dually and single-rear-wheel three-quarter and one-ton applications. Always verify your truck's pattern before ordering.
Do I need different front and rear wheels for a dually? Yes. Dually designs here use separate front and rear part numbers with different offsets — for example the 002FBK front at +102 and the 002RBK rear at -125 — so the rear can clear the dual-tire axle.
What construction are these Ultra 8x165.1 wheels? The eight-lug models in this pattern are monoblock — a single-piece cast design suited to the towing and hauling loads these trucks see.
