RT233 Monster
Raceline RT233 Monster: Aggressive Off-Road Monoblock
The Raceline RT233 Monster is a monoblock truck and off-road wheel built for a bold, deep-lip stance. Its bold spoke face carries a machined finish that catches light across the barrel, and the negative offsets push the wheel out for that planted, wide-track look serious rigs are after. It sits within the wider Raceline wheel lineup as one of the brand's more aggressive fitments.
Sizes and fitments in stock
The RT233 Monster comes in a single, focused size: 17x9.5. You choose between two offsets, -19 and -32, both cut for a deep concave face and generous lip. What makes this model flexible is its bolt-pattern range, which covers everything from mid-size trucks to heavy-duty haulers.

Finish
The RT233 Monster is offered in a Machined finish. If you want to compare tones across the range, the silver Raceline wheels and black Raceline wheels collections show the alternatives.
Price and who it suits
Pricing runs from $525 to $599 per wheel, putting the Monster in reach for a full set on trucks, SUVs and off-road builds that need a wide, negative-offset look with real bolt-pattern coverage. If you're weighing other Raceline options, the RT260M Avenger is a different aggressive face, the RT291M Ryno and the machined RT951M Ryno offer alternate Ryno-family styling, and the 146B Matrix leans toward a blacked-out street-truck look. The 145M Encore BMF is another dark option worth a look.
