002RBK Modular Dually

Ultra 002RBK Modular Dually: Built for Dual-Rear-Wheel Trucks

The Ultra 002RBK Modular Dually is a monoblock dually wheel engineered specifically for dual-rear-wheel one-ton trucks. Its clean, modular-look face carries the deep negative offsets a dually front-and-rear stagger demands, so both the steer and drive positions sit correctly under heavy 8-lug pickups and cab-and-chassis rigs. This is part of the Ultra truck lineup, and it is aimed squarely at work-and-tow duty rather than street show.

Sizes and Fitments Stocked

The 002RBK Modular Dually runs in 16-inch and 17-inch diameters, in 6- and 6.5-inch widths. Offsets are deep by design at -125 and -140 to set the correct inner and outer dually spacing. Bolt patterns cover 8x165.1, 8x170 and 8x200, the three most common heavy-duty 8-lug layouts.

Concrete examples in stock include the 8x165.1 16x6 -125 Gloss Black for GM and Dodge duallys, the 8x170 16x6 -125 Gloss Black for Ford Super Duty, and the taller 8x200 17x6.5 -140 Gloss Black for late-model F-450/F-550. If you want to confirm the numbers work on your dually, the fitment calculator lays the offset and width against your setup. The Ultra 8x165.1 wheels page groups more options in that pattern.

Finish

The 002RBK Modular Dually comes in Gloss Black - a durable, low-maintenance look that suits work trucks and hides road grime. It sits alongside other black Ultra wheels if you're matching a fleet or a build already running dark trim.

Price and Who It Suits

Pricing runs from $358 to $417 per wheel depending on diameter and pattern. This wheel suits owners of 8-lug dual-rear-wheel trucks who need a correct-offset dually wheel for towing, hauling or fleet use - not lifted-truck styling. If you run a single-rear-wheel truck or a lifted rig, look at the 258SB Prowler Truck or its 258SB Prowler Lifted version, while the 254U Carnivore gives a more aggressive off-road face. For work vans, the 450BM Toil Van and 470SB Judgement Van cover those load ranges, and the simpler 51K steel-style is a budget alternative.

We are an authorized Ultra dealer selling 100% genuine wheels, with free shipping on all orders and 30-day returns on unmounted wheels. Flexible payment through Affirm, Katapult, Klarna, PayPal Credit and Snap Finance is available at checkout. For dually spacing questions, call our fitment team at 813-535-5801.
