158B Impulse

Raceline 158B Impulse: Monoblock Wheels for Cars and Trucks

The Raceline 158B Impulse is a monoblock wheel with a clean, multi-spoke split face that carries a modern, aggressive look across both car and truck fitments. Built as a single piece, it suits daily drivers, crossovers and light trucks that want a bold gloss black stance without moving into heavier off-road territory. It sits in the same Raceline lineup as the brand's other street and truck designs.

Sizes and fitments in stock

The 158B Impulse is stocked in 18, 20 and 22-inch diameters, in widths of 8, 8.5 and 9.5, with offsets of 15 and 35. Bolt patterns run broad, covering 5x110, 5x114.3, 5x115, 6x120, 6x132 and 6x139.7, so it works on a wide spread of import cars, SUVs and half-ton trucks.

For concrete examples: the 18x8 +35 in 5x114.3/5x127 is a common car spec, while the 18x8 +35 in 6x139.7/6x135 covers popular truck patterns. Stepping up, the 20x8.5 +35 and the deeper 20x8.5 +15 give a more filled fender and aggressive setup. You can browse all Raceline 6x139.7 wheels and Raceline 5x127 wheels if you're targeting those patterns specifically.

Finish

The Impulse is offered in Gloss Black - a straightforward, high-shine finish that reads clean on light and dark vehicles alike. More of the range lives on the Black Raceline wheels page.

Price and who it suits

Pricing runs from $285 to $447 per wheel depending on diameter, width and pattern. That puts the 158B Impulse in reach for owners who want a monoblock wheel with wide fitment coverage at a sensible price. If this face isn't quite your style, the 146B Matrix offers a different black spoke pattern, the 141B Mystique Black leans more intricate, and the 145M Encore BMF carries a machined black-and-milled look. Truck buyers may also want to compare the RT951B Ryno and the RT260M Avenger, both aimed at more rugged builds.
