421B X

Focal 421B X: a compact monoblock wheel for tuner and daily builds

The Focal 421B X is a monoblock wheel built around a tidy, multi-spoke face aimed at small-diameter street and tuner setups. It comes in modest diameters and widths with conservative offsets, so it sits cleanly under stock and lightly modified fenders rather than chasing an aggressive poke. If you run a hatch, sedan or compact and want a clean, one-piece look, this is the shape it takes. It sits alongside the rest of the Focal lineup as one of the brand's smaller-diameter offerings.

Sizes and fitments stocked

The 421B X is stocked in 15, 16 and 17 inch diameters, in widths of 6.5, 7 and 7.5, with offsets of +38, +42 and +48. Bolt patterns cover 4x100, 5x100, 5x108, 5x112 and 5x114.3, including several dual-drilled combinations. A few concrete examples of what that means:

Browse by size and pattern through the 16 inch Focal and 17 inch Focal pages, or by pattern via 5x100, 4x100, 5x108 and 5x114.3.

Finish

The 421B X is offered in Satin Black with a Satin Clear Coat, a low-gloss dark finish that suits most colors. See it grouped with other black Focal wheels, or if you want a warmer tone from another model, the bronze Focal range.

Price and who it suits

Pricing runs from $191 to $223 per wheel depending on size. It suits daily drivers and clean tuner builds that want a compact monoblock look without a big spend. If you want a different face in the Focal family, the 456 F-56 and 455U F-55 take a different spoke design, the 452SB F-52 and 451SB F-51 offer other satin-black styles, and the 449SB F-14 is another compact option to compare.
