ICON Alloys Alpha 20x9 8x180 +12mm Satin Black Wheel

The ICON Alloys Alpha is an aluminum alloy wheel sized 20x9 with an 8x180 bolt pattern, 12mm offset, and 5.5-inch backspace, finished in Satin Black. The 8x180 bolt pattern is specific to a narrow range of heavy-duty truck applications; confirm fitment against your vehicle's bolt pattern, offset requirements, and brake caliper clearance before ordering.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

Engineered Dimensions, Not Generic Sizing

The Alpha's 12mm offset and 5.5-inch backspace determine how far the wheel face sits inboard or outboard of the hub face, which directly affects caliper clearance, suspension travel, and steering geometry. A wheel with dimensions dialed for a specific bolt pattern and application avoids the rubbing, scrubbing, and binding that come from adapting a generic fitment.

Aluminum Alloy Construction

The Alpha is cast from aluminum alloy, which reduces unsprung weight and rotating mass compared to steel. Lower unsprung weight means the suspension responds more quickly to terrain changes; lower rotating mass reduces the inertia the drivetrain works against. Both matter on and off pavement. The Satin Black finish provides a low-glare appearance suited to work-truck and overland builds alike.

Features

• Aluminum alloy construction: strength suited for off-road use with reduced unsprung and rotating mass
• Application-specific offset and backspace: 12mm offset and 5.5-inch backspace optimize wheel position and caliper clearance
• 8x180 bolt pattern: matches a specific heavy-duty truck bolt circle; confirm vehicle fitment before ordering
• Satin Black finish: low-glare matte-satin appearance
• California Proposition 65: this product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm

Specifications

Who This Is For and Isn't

The Alpha in 20x9 / 8x180 / +12mm is for truck owners whose vehicle uses an 8x180 bolt pattern and whose suspension and brake setup is compatible with a 12mm offset and 5.5-inch backspace. Professional mounting and balancing of an appropriately sized tire before installation onto the vehicle is recommended.

This wheel does not fit vehicles with any other bolt pattern. No vehicle-specific fitment list (make, model, or model years) is confirmed in the available product data; buyers should verify bolt pattern, offset, and caliper clearance against their specific vehicle before purchasing.

Common Questions

What vehicles use an 8x180 bolt pattern?

The 8x180 bolt pattern is used on a specific range of heavy-duty trucks. No confirmed make/model/year fitment list is available in the current product data for the ICON Alloys Alpha 20x9 in this configuration. Buyers should verify their vehicle's bolt pattern, hub bore, and offset requirements before ordering.

What is the difference between offset and backspace?

Offset is the distance in millimeters from the wheel's hub-mounting face to its centerline: positive offset means the hub face is toward the street side of the wheel. Backspace is the distance from the hub-mounting face to the inner lip. The Alpha carries a +12mm offset and 5.5-inch backspace; both figures affect caliper clearance and how far the wheel sits inboard or outboard.

Is professional installation required?

ICON Alloys recommends professional mounting and balancing of an appropriately sized tire before the ICON Alloys Alpha wheel is installed onto the vehicle. An installation guide is available from ICON Alloys.

Does this wheel carry a Proposition 65 warning?

Yes. The ICON Alloys Alpha contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm, as required to be disclosed under California Proposition 65.
