178B Mongoose

Ultra 178B Mongoose Wheels

The Ultra 178B Mongoose is a monoblock truck and off-road wheel built for rigs that need a strong, no-nonsense face and a wide spread of fitments. Its aggressive split-spoke design carries a deep concave look that suits lifted trucks, Jeeps and heavy-duty haulers alike. It sits in Ultra's truck and off-road lineup as a dark, machined option for drivers who want presence without fuss.

Sizes and fitments stocked

The Mongoose comes in 15-, 16- and 17-inch diameters, with widths of 8, 9 and 10 inches. Offsets run from a deep -44 through -19, -06, +01, +10, +12, +20 up to +25, so it works on everything from lifted setups wanting poke to more conservative stances.

Bolt patterns are broad: 5x114.3, 5x127, 5x139.7, 6x135, 6x139.7, 8x165.1 and 8x170. That covers half-ton trucks, HD dually platforms and Jeep applications. For example, a 15x8 -19 in 6x139.7 tucks under classic mini-trucks, while a 16x8 -06 in 8x170 clears Super Duty axles. The 17x9 +01 in 8x165.1 and a matching 16x8 +10 in 5x139.7 round out the popular sizes. See more Ultra 8x165.1 wheels if you run a 3/4-ton GM or Dodge.

Finish

The Mongoose is offered in Gloss Black w/Machined Accents — a dark face with machined highlights that catch light on the spokes. It fits right in with the rest of the black Ultra wheels range.

Price and who it suits

Pricing runs from about $216 to $310 per wheel depending on size and bolt pattern. That makes the Mongoose a sensible choice for truck and Jeep owners who want an aggressive machined look across a wide fitment span without stepping into premium money. If you want a different flavor from the same brand, the 258SB Prowler Truck gives a lifted-truck stance, the 258SB Prowler Jeep is tuned for Jeep bolt patterns, the 263BM Sinister runs a darker mesh, and the 254U Carnivore adds a simulated beadlock ring. The 450C Toil is another split-spoke option worth a look.
