The THRET Offroad 901 Monarch is a cast aluminum wheel for the 2021, 2022, 2023, 2024, 2025, and 2026 Ford Bronco. THRET Offroad gives it an 8 split-spoke face with exposed lugs and a deep lip. It is built for big diameters, with 20-inch and 22-inch sizes and widths up to 12 inches. The wheel is drilled for the Bronco's factory 6x139.7 bolt pattern, so it bolts straight on with no adapters.

Two Finishes

The 901 Monarch is listed here in two finishes. Gloss Black is a shiny black across the whole wheel. Gloss Black/Milled keeps the shiny black face and adds cut metal accents along the spokes.

Not every size comes in every finish. Pick your finish first. The size menu then shows only the sizes that finish comes in.

Sizes and Offsets

The 901 Monarch comes in four size and offset combinations for the Bronco. The 20x10 and 22x10 each come with a -21mm offset. The 20x12 comes with a -44mm offset. The 22x12 comes with a -51mm offset and is available in Gloss Black/Milled.

Every size in the menu lists three numbers. The first is the wheel size, such as 22x12. That means a 22-inch diameter and a 12-inch width. The second is the offset. The third is the backspacing.

What Offset and Backspacing Mean

Offset is the distance between the center of the wheel and the face that bolts to your hub. It is measured in millimeters. Every 901 Monarch size has a negative offset, which moves the wheel out toward the fender. The -44mm and -51mm sizes push the wheel out the farthest.

Backspacing is the distance from the mounting face to the inner edge of the wheel. It is measured in inches. The 901 Monarch ranges from 4.5 to 4.8 inches on the Bronco sizes. The 12-inch-wide sizes add their extra width on the outside, so the tire sits well past the fender.

Fitment

The 12-inch-wide sizes are built for an aggressive stance. They stick out well past the factory fender flares. Most builds that run them also run a lift, wider flares, or trimmed or deleted fenders. The 10-inch-wide sizes sit farther in. Check your tire size, lift height, and fender setup before you order.

The 901 Monarch uses the 6x139.7 bolt pattern that Ford uses on every 2021 through 2026 Bronco. The center bore is 106.1mm, which is larger than the Bronco hub. That means the lug nuts center the wheel on the hub.

Each wheel carries a 2,500-pound load rating. The lug seat is a conical acorn and spline style. The wheel is DOT approved and works with factory TPMS sensors. A center cap is included with each wheel.

Wheels are not accepted for return once a tire has been mounted.

Installation

A tire shop mounts and balances your tires on the 901 Monarch. The wheels then bolt to the Bronco with lug nuts that match the conical seat. Plan on about two hours for a full set, including mounting and balancing.

Bronco Forge lists the offset and backspacing for every size right in the menu. That way you can match the stance you want before the wheels ship. THRET Offroad backs the 901 Monarch with a 2-year manufacturer warranty.
