KM556 CRUX

KMC KM556 CRUX: A Monoblock Wheel Built for Trucks and SUVs

The KMC KM556 CRUX is a monoblock wheel with a bold, split-spoke face that reads clean and aggressive on modern trucks, Jeeps and SUVs. As a single-piece monoblock, it keeps the look tidy while covering a wide spread of truck and off-road fitments. It sits alongside the rest of the KMC lineup as a street-and-trail all-rounder rather than a dedicated beadlock crawler.

Sizes and Fitments in Stock

The CRUX is stocked in 17, 18 and 20 inch diameters, in widths of 8.5, 9 and 10 inches, with offsets of -18, 0, +1, +18 and +25. Bolt patterns run wide: 5x127, 6x114.3, 6x135, 6x139.7, 8x165.1, 8x170 and 8x180 — so it fits everything from a Wrangler to heavy-duty diesels.

The 17x8.5 sizes are the volume sellers. You can grab the popular 6x135 17x8.5 +0 or 6x139.7 17x8.5 +0 for common half-ton trucks, the 5x127 17x8.5 +0 for JK/JL Jeeps, or step to a tucked 6x114.3 17x8.5 +25. Not sure which offset clears your build? Run the numbers through our fitment calculator.

Finishes

Three finishes are stocked: Gloss Gunmetal, Blackout and Gloss Silver W/ Machined Face. See the darker options with other black KMC wheels or the brighter face among silver KMC wheels.

Price and Who It Suits

The KM556 CRUX runs from $370 to $590 depending on size and fitment. It suits truck, Jeep and SUV owners who want an aggressive monoblock look and a huge choice of bolt patterns without the price of a forged beadlock. If beadlocks are what you're after, KMC has a full run of those instead — the KM233 HEX Beadlock, the desert-focused KM234 Grenade Desert Beadlock and the forged KM444 MESA Forged Beadlock. For a simpler street wheel, the KM102 Signal and KM301 Turbine are lighter-styled alternatives, while the KM446 MESA Forged Monoblock is a forged step up.
