ICON Alloys Hulse 18x9 8x170 +6mm Silver Machined Wheel

The ICON Alloys Hulse is an 18×9 aluminum alloy wheel built for HD 8-lug applications, carrying a 4,000 lb load rating per wheel. Its motorsport-inspired concave profile, 12-spoke design, thick lip, and oversized ring bolts are finished in Silver Machined with a clear powder coat for corrosion resistance. Offset is +6mm with 5.25" backspace on an 8×170 bolt pattern.

Engineered Fitment, Not Just Styling

The Hulse's backspace and offset figures were developed specifically to reduce scrub radius on HD platforms. A tighter scrub radius keeps the tire contact patch closer to the steering axis, which translates to more predictable steering feel and reduced kickback over rough terrain on a heavy truck that already asks a lot of its front axle.

Caliper and Suspension Clearance by Design

Caliper clearance and wheel position are engineered into the Hulse's geometry rather than left to chance. The wheel works with the suspension's full travel range without rubbing or binding. This matters when the truck is loaded or the suspension is cycling hard on uneven ground. The Hulse is designed to complement ICON Vehicle Dynamics suspension systems, where the offset and backspace targets are already dialed in for those applications.

Construction Built for Off-Road Load

Aluminum alloy construction keeps unsprung and rotating mass lower than comparable steel wheels, which benefits both on-road ride quality and off-road suspension response. The machined surface is protected by a clear powder coat finish. Each Hulse carries a 4,000 lb load rating. Professional mounting and balancing of an appropriately sized tire before installation onto the vehicle is recommended.

Who This Is For and Isn't

The Hulse in this configuration suits HD trucks running an 8×170 bolt pattern where the buyer wants an 18×9 wheel with a +6mm offset and 5.25" backspace, particularly trucks already running or planning an ICON Vehicle Dynamics suspension system, where the geometry targets align.

This listing is for one wheel in Silver Machined only; the Double Black finish is a separate listing. The 8×170 bolt pattern does not fit vehicles with 6-lug or 5-lug applications. Professional tire mounting and balancing is required before installation.

Common Questions

What bolt pattern does this wheel fit?

This Hulse wheel uses an 8×170 bolt pattern, designed for HD 8-lug applications. It is not compatible with 6-lug or 5-lug vehicles. Buyers should confirm their vehicle's bolt pattern, hub bore, and brake caliper clearance before ordering.

What is the load rating for the Hulse?

Each ICON Alloys Hulse wheel in this configuration carries a 4,000 lb load rating, making it suited for HD truck applications where wheel load capacity is a consideration alongside fitment geometry.

Does the offset and backspace work with a lift kit?

The Hulse's +6mm offset and 5.25" backspace were engineered to reduce scrub radius and optimize wheel position for suspension travel and steering function. The geometry is specifically developed to complement ICON Vehicle Dynamics suspension systems; buyers using other lift brands should verify clearance with their installer.

Is professional installation required?

Professional mounting and balancing of an appropriately sized tire onto the Hulse wheel before installation onto the vehicle is recommended. Wheel and tire fitment on HD trucks involves torque, hub-centric fit, and brake clearance checks that are best confirmed by a qualified installer.
