Why 6x139.7 Matters
6x139.7 (also written 6x5.5) is the workhorse six-lug pattern behind countless trucks and body-on-frame SUVs, which is why LOCK OFFROAD carries so many of its silhouettes here. Every model in this group is a one-piece monoblock casting or forging, a construction style chosen for strength and simplicity under load. If you're cross-shopping by stance, you can also explore the 6x135 fitment or step over to heavy-duty 8x170 and 8x180 patterns.
Models & Finishes in 6x139.7
Most of the off-road lineup is offered in this pattern. Trail-and-rock favorites include the KRAWLER, LUNATIC, TRAIL, MOJAVE, and YOSEMITE. Aggressive concave styles like the 50CAL, BAJA, COMBAT, and COMMANDO round out the look, alongside the OLYMPUS and ONYX.

Finishes carried in this pattern span matte and machined tones, including Matte Black W Matte Black Ring, Matte Black W Gloss Black Ring, Matte Bronze W Matte Black Ring, Matte Desert Bronze W Matte Black Ring, Matte Grey W Matte Black Ring, Matte Silver W Matte Black Ring, Matte Blue, and Machine With Clear Coat. To shop by tone, see the black, bronze, gray, silver, and blue pages.
Fitment Coverage
Within 6x139.7, diameters run from a compact 17-inch up to 20-inch, making this pattern well suited to trucks and SUVs that share the popular six-lug hub. If your build calls for a different size, the 17-inch and 20-inch pages narrow things down, while 18- and 22-inch options appear in other patterns. Always confirm offset and width against your specific vehicle before ordering.
How to Choose
Start with the look: matte black rings deliver a stealthy stance, while bronze and desert bronze warm things up. The COMBAT 17x9 +1 and KRAWLER 17x9 -12 show how aggressive offsets change the fitment, and the 50CAL 17x9 +0 sits as a balanced choice. Rock crawlers should look at beadlock options such as the INVADER CASTING BEADLOCK or the forged INVADER FORGED BEADLOCK, while the GRIT 17x8.5 +25 suits milder lifts. Every order ships free, and financing is available through Affirm.
