Why the 6x139.7 pattern matters here
The 6x139.7 (6x5.5) pattern is a common full-size truck and SUV spacing, and KMC Powersports pairs it with rugged monoblock builds designed for hard use. A representative example, the IMPACT UTV BEADLOCK 6x139.7 15x7 +10 Satin Black, is a 15-inch monoblock wheel with a genuine beadlock ring, a 100.30 hub bore, and a 1,250 lb load rating — the kind of specs that separate a purpose-built off-road wheel from a street casting. You can compare the whole range on the full KMC Powersports lineup.
Which models & finishes are offered in 6x139.7
Four KMC Powersports models carry the 6x139.7 pattern: the KS239 IMPACT UTV BEADLOCK, the KS241 TORX UTV BEADLOCK, the KS242 AZTEC UTV BEADLOCK, and the forged KS436 IMPACT FORGED BEADLOCK. The IMPACT UTV BEADLOCK comes in Machined and Satin Black; the TORX and AZTEC add Gloss Black Milled and two-tone ring options, with the AZTEC offering a Matte Bronze with Matte Black ring; and the KS436 is offered in Raw Machined Forged.

Construction notes
Each of these four is a monoblock (one-piece) wheel. The KS436 IMPACT FORGED BEADLOCK is a forged monoblock, while the KS239, KS241, and KS242 are cast monoblock beadlocks — a strong, simple structure well suited to real trail abuse.
Fitment coverage
In this pattern the diameter offered is 15 inches, matching the UTV and off-road tire sizes these wheels are designed around. KMC Powersports also builds many of these same designs in other spacings, so if your machine runs a different bolt pattern, check 4x137, 4x156, or 5x114.3. The IMPACT, TORX, and AZTEC beadlocks, for instance, all cross over to 5x114.3 as well. Looking at diameters instead? See 15-inch and 14-inch options across the brand.
How to choose
Start with your confirmed bolt pattern and hub bore, then decide between a cast beadlock and the forged KS436 based on how hard you ride and how much weight savings you want. Match width and offset to your tire and fender clearance — the TORX 15x7 +38 sits differently than a wider +0 setup, so the +10 offset on the IMPACT beadlock splits the difference. Finish is the last call: Machined and Raw Machined Forged read bright and technical, while Satin Black and Gloss Black Milled keep things stealthy. If you're between designs, compare the IMPACT and AZTEC face styles side by side.
