Fuel Mono 6x139.7 Wheels: One-Piece Monoblock Style for Trucks and SUVs
Fuel Mono 6x139.7 wheels bring the brand's aggressive, deep-concave monoblock styling to one of the most common six-lug truck and SUV bolt patterns. The 6x139.7 fitment is carried across several Fuel Mono designs, with diameters reaching from the street-friendly 20-inch range up to bold 26-inch sizes depending on the model you choose. Every order ships free, and financing is available through Affirm.

Within the broader six-lug family, 6x139.7 covers a huge swath of popular hauler and lifted-truck platforms, which is why so many models in the full Fuel Mono lineup are offered in it.
Why Fuel Mono Stands Out
Fuel Mono designs are built as one-piece monoblock wheels, meaning the spokes, barrel, and lip are machined from a single casting rather than bolted together. That construction is a defining trait of this lineup and lends itself to the chunky, concave profiles the brand is known for. Pair that with milled-accent and polished finishing and you get a face that reads aggressive at a glance, whether on a daily-driven half-ton or a built show truck.
Models & Finishes Available in 6x139.7
Several designs carry the 6x139.7 pattern directly. The DD37 FF37 is offered in 22-inch Gloss Brushed Polished, while the DD71 FF71 covers the 20-inch slot in Matte Black Milled. The flexible FF109, FF110, FF111, FF112, FF115, and FF117 styles span 20- through 26-inch diameters in Gloss Black Milled and Polished.
Across the wider 6x139.7 selection you'll find finishes including Gloss Black Milled, Matte Black Milled, Gloss Brushed Polished, High Luster Polished, Polished, and a Custom Finish option. If you want a darker, stealthier look, browse the black Fuel Mono wheels. A standout ready-to-ship option is the DD37 FF37 6x139.7 22x10 -25 Gloss Brushed Polished, and the DD71 FF71 6x139.7 20x9 +1 suits a tucked, daily setup.
Fitment Coverage
This page focuses on the 6x139.7 bolt pattern, a six-lug standard found on many full-size trucks and SUVs. If your vehicle runs a different pattern, the lineup also spans options like 5x139.7, 6x135, 5x114.3, 5x135, 8x165.1, 8x170, and 8x180 for heavy-duty rigs. By diameter, you can shop 20-inch, 22-inch, 24-inch, and 26-inch Fuel Mono wheels.
How to Choose
Start by confirming your bolt pattern is 6x139.7, then pick a diameter that clears your brakes and matches your stance goals. A 20-inch fitment like the DD71 FF71 keeps sidewall and ride comfort, while 22- to 26-inch sizes deliver a more dramatic face. Match the width and offset to your fender line and any lift or leveling, and choose a finish that fits the build: polished and brushed faces pop, while milled-black faces ground the look. When in doubt, the FF109-FF117 designs offer the widest size flexibility in this pattern.
