ICON Alloys Hammer PRO 17x8.5 5x5 -6mm Charcoal Wheel

The ICON Alloys Hammer PRO is a 17×8.5 aluminum alloy wheel with a 5×5 bolt pattern, -6mm offset, and 4.5" backspace in a Charcoal finish, built for truck, Jeep, and SUV owners who run low tire pressures off-road and need bead retention without sacrificing DOT compliance. The patented InnerLock system holds the tire bead under extreme side loads while remaining fully street-legal, unlike traditional bead lock wheels. Load rating is 3,650 lb per wheel.

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.

Bead Retention Without the Bead Lock Trade-Offs

Traditional bead lock wheels clamp the tire bead mechanically, which works off-road but brings real costs: frequent re-torquing, specialty mounting tools, added rotational mass, and a hard ban on public roads in most jurisdictions. The Hammer PRO's InnerLock technology uses hardened alloy retention pins (thermochemically treated for corrosion resistance and sealed with SAE J1926 O-rings) to keep the bead seated under load without any of those drawbacks. The pins are removable, reusable, and replaceable, so the system can be serviced with standard shop equipment. ICON validated InnerLock through the FMVSS No. 139 Tire Bead Unseat Resistance Test (modified to 10 psi); independent lab testing exceeded the machine's mechanical limits at over 7,600 lb of load without a de-bead event.

Dimensions Engineered for Suspension Clearance

The Hammer PRO's -6mm offset and 4.5" backspace were developed specifically to maximize caliper clearance, reduce scrub radius, and keep the wheel positioned for full suspension travel and steering function. Buyers who have already invested in a lift or performance suspension system benefit from a wheel that does not compromise the geometry that system was tuned to deliver.

HALO Wheel Armor Included

Every Hammer PRO ships with HALO Wheel Armor, a high-grade aluminum ring that protects the outer face from trail rash. The armor is segmented into 90° sections, so a single damaged quarter can be replaced without swapping the entire ring. Sections are also available in different finishes, allowing the look to be changed independently of the wheel itself.

Features

• Patented InnerLock bead retention (U.S. Patent No. 11,090,976): keeps the tire bead seated at low pressures; fully DOT compliant
• 3,650 lb load rating: strength-tested aluminum alloy construction
• Hardened retention pins: removable, reusable, replaceable; SAE J1926 O-ring sealed; thermochemically treated for corrosion resistance
• Included HALO Wheel Armor: high-grade aluminum outer-face protector, replaceable in 90° segments
• Caliper-clearance geometry: offset and backspace developed to reduce scrub radius and preserve suspension travel
• No shims or special tools required for tire mounting with a wide variety of tire sizes

Specifications

Who This Is For and Isn't

The Hammer PRO suits truck, Jeep, and SUV owners running a 5×5 bolt pattern who air down for off-road traction and want bead retention that is legal for daily street driving. The -6mm offset and 4.5" backspace make it a strong match for lifted builds where caliper clearance and scrub radius are a concern.

This wheel may not be compatible with all TPMS sensors that use rigid valve stems; flexible rubber valve stems are recommended for InnerLock pin clearance. No vehicle-specific fitment list is available for this product: confirm bolt pattern, offset, and hub bore against your specific vehicle before ordering. Professional tire mounting and balancing is recommended prior to installation.

Common Questions

Is the Hammer PRO legal for street use?

Yes. Unlike traditional bead lock wheels, the Hammer PRO with InnerLock technology is fully DOT compliant and legal for on-road use. The bead retention system works through internal alloy pins rather than an external clamping ring, which is the design element that makes conventional bead locks street-illegal in most jurisdictions.

Will this wheel work with my existing TPMS sensors?

The Hammer PRO may not be compatible with all TPMS sensors that use rigid valve stems. ICON's Application Note #211 recommends flexible rubber valve stems to clear the InnerLock retention pins during tire mounting. Confirm your sensor type before ordering, or plan to switch to flexible stems.

What is included with each Hammer PRO wheel?

Each Hammer PRO wheel ships with HALO Wheel Armor, a high-grade aluminum outer-face protector that mounts to the wheel and is replaceable in 90° segments. The InnerLock retention pins are part of the wheel assembly. Tires, lug nuts, and TPMS sensors are not included.

Can the InnerLock pins be replaced if damaged?

Yes. The hardened alloy retention pins in the Hammer PRO's InnerLock system are designed to be removable, reusable, and replaceable. Each pin uses a SAE J1926 O-ring seal and is thermochemically treated for corrosion resistance, so individual pins can be swapped without replacing the wheel.

Does this wheel require special tools or shims for tire mounting?

No shims or special tools are required to mount a wide variety of tires on the Hammer PRO. ICON recommends professional mounting and balancing prior to installing the wheel on the vehicle, and flexible rubber valve stems are recommended to clear the InnerLock pins.
