Why 6x139.7 Black Rock wheels matter
Black Rock builds function-forward off-road styles with offsets, backspacings and bolt patterns aimed squarely at truck, Jeep and 4x4 duty. The 6x139.7 pattern (also written 6x5.5) is one of the most common six-lug truck standards, so these designs slot onto a wide swath of pickups and body-on-frame SUVs. The look here leans utilitarian and tough — think simple spokes and clean faces rather than show-polish flash.
Which models & finishes carry 6x139.7
Several Black Rock designs offer the six-lug 6x139.7 fitment. The 909B Type D Alloy is a 17-inch monoblock in Matte Black, seen in the 909B 6x139.7 17x8 +0 Matte Black. The 929B Blackjack and the 942B Black D-Window are both Matte Black monoblocks in smaller 15- and 16-inch sizes, with the D-Window also reaching 17 inches. The versatile 997B Soft 8 covers 15, 16 and 17 inches in Matte Black — the 997B Soft 8 17x8 is a good example of the classic eight-hole steel look.
For larger diameters, the 935B is a 20-inch monoblock offered in Gloss Black w/Milled Edges, shown in the 935B 6X135/6x139.7 20x9 +12. Its sibling 965B shares the 20-inch monoblock footprint in Matte Black. Across the six-lug wheels, the two finishes you'll find are Matte Black and Gloss Black w/Milled Edges.
Fitment coverage
Diameters in this bolt pattern span 15, 16, 17 and 20 inches. If your build needs a different lug spacing, Black Rock also covers 5x114.3, 5x127, 5x139.7, 5x120.65 and the heavy-duty 8x165.1 pattern. Prefer to shop by size? See the 15-inch, 16-inch and 17-inch pages. Always confirm the exact bolt pattern, diameter, width and offset against your vehicle before ordering.
How to choose
Match the six-lug pattern first, then pick a diameter for your tire plans: 15- and 16-inch fitments like the 929B Blackjack suit taller sidewalls and trail flex, while a 20-inch 935B carries a more modern street-truck stance. Choose Matte Black for an understated, stealthy build or Gloss Black w/Milled Edges when you want a touch of contrast on the spoke faces. Cross-check offset and width against your fenders and suspension to avoid rubbing.
