991B Assault

Raceline 991B Assault: Rugged Monoblock Truck Wheel

The Raceline 991B Assault is a monoblock wheel built for trucks, SUVs and off-road rigs that need a strong single-piece design and an aggressive face. Its deep, split-spoke pattern reads mean without going busy, and the wide range of lug counts means it works on everything from mid-size trucks to full-size heavy-duty haulers. It sits alongside the rest of the Raceline lineup as the go-to for owners who want a durable, no-nonsense wheel.

Sizes and fitments stocked

The 991B Assault comes in 16, 17, 18 and 20-inch diameters, in 8 and 9-inch widths. Offsets run from a deep -12 up through +00, +12, +18, +20, +25 and +30, so you can dial in anything from a tucked stance to a poke.

Bolt patterns cover a lot of ground: 5x114.3, 5x127, 5x139.7, 5x150, 6x135, 6x139.7, 8x165.1 and 8x170. For hard-lug applications, the 8x165.1 20x9 -12 and the 8x165.1 17x9 -12 are both stocked. On 5-lug rigs, look at the 5x114.3 16x8 +0, the 5x127 17x9 +18 or the taller 5x127 18x9 +25. Browse the full Raceline 5x127 and Raceline 8x165.1 selections if you want to see the sizes side by side.

Finishes

The Assault is offered in dark, workmanlike finishes. See the black Raceline options for the classic murdered-out look, or the gray Raceline shades for something a touch softer against a colored truck.

Price and who it suits

The 991B Assault runs from $229 to $413 per wheel depending on size and fitment. That puts it squarely in reach for daily-driven trucks, weekend trail rigs and towing setups that want a tough monoblock wheel without a specialty price tag. If you like the look but want to compare, the RT951B Ryno and RT291M Ryno are more off-road-focused Raceline patterns, the RT260M Avenger takes a different spoke approach, and the 146B Matrix and 145M Encore BMF lean toward a more street-styled face.
