Owners who want a deeper concave face and more styling options than a monoblock allows, without moving to a full 3-piece. Popular on performance cars, luxury SUVs and show builds.

  4. Your wheels ship ready to mount, compatible with factory hardware whenever possible.

Duoblock FAQ

What's the difference between a duoblock and a monoblock?
A monoblock is one continuous forging. A duoblock uses a two-piece build around a forged center, which opens up deeper concave and more finish and hardware combinations.

Duoblock vs 2-piece vs 3-piece: which should I pick?
Duoblock is the styling step up from monoblock. 2-piece and 3-piece add the widest width and offset range and let a damaged barrel be replaced. See our construction guide.

Can I order a staggered set?
Yes. Give us front and rear width and offset in your quote request.
