RT231 Monster

Raceline RT231 Monster: Truck and Off-Road Monoblock Wheel

The Raceline RT231 Monster is a 17-inch monoblock built for trucks and off-road rigs that need a strong single-piece wheel with an aggressive face. Its deep, spoked design and machined outer ring give it presence on lifted and stock-height platforms alike, and the range of bolt patterns means it works on both light-duty and heavy-duty applications. It sits within the wider Raceline lineup as one of the brand's off-road-focused models.

Sizes and fitments stocked

The RT231 Monster comes in a single 17-inch diameter, offered in two widths: 17x8.5 and 17x9.5. The 8.5-inch runs a 0 offset, while the wider 9.5-inch runs an aggressive -32 offset for a pushed-out, planted stance. Bolt patterns cover 5x127, 5x139.7, 6x139.7 and 8x165.1, so it suits Jeep, Ram, GM and heavy-duty Ford and Dodge trucks.

Concrete examples in stock: the 8x165.1 17x8.5 0 for HD diesel trucks, the 5x127 17x8.5 0 for Jeep Wrangler and Gladiator, and the wider 6x139.7 17x9.5 -32 for full-size half-tons. There is also a 5x139.7 17x9.5 -32 for classic Ram and Jeep JK setups. You can cross-check spacing on our fitment calculator, and browse the full Raceline 8x165.1, 6x139.7 and 5x127 ranges.

Finish

The RT231 Monster ships in Black and Machined Ring — a satin black face with a machined outer lip for contrast. If you want more black options across the brand, see the black Raceline wheels page.

Price and who it suits

Pricing runs from $525 to $552 per wheel depending on width and bolt pattern. It suits truck and off-road owners after an aggressive monoblock at a working-man price, whether you're on a lifted HD or a daily half-ton. Flexible payment options — Affirm, Katapult, Klarna, PayPal Credit and Snap Finance — are available at checkout via financing.

Other Raceline models to consider

If the Monster isn't quite the look, the RT951M Ryno and RT951B Ryno offer a different off-road spoke pattern, the RT260M Avenger brings a bolder mesh face, and the RT291M Ryno is another rugged option. For a cleaner street look, the 146B Matrix takes a more refined direction.
