Important ABS Sensor Information

2020–2026 GM HD 2500HD / 3500HD trucks use an ABS wheel-speed sensor mounted in the steering knuckle rather than integrated into the wheel bearing assembly.

When installing the Axiom Supply AX515208, retain and reuse the truck's existing ABS wheel-speed sensor and cable.

The wheel-speed sensor is not included with or integrated into this hub assembly.

Description

The Axiom Supply AX515208 Wheel Bearing & Hub Assembly is engineered for truck owners and professionals who demand dependable performance from their 2020–2026 Chevrolet Silverado HD and GMC Sierra HD.

Heavy-duty GM trucks place substantial loads on the front wheel bearings, particularly when towing, hauling, running oversized tires, operating with modified suspension, or spending extended time on rough terrain. The AX515208 is designed specifically to perform in these demanding conditions.

At the heart of the assembly is Axiom's precision tapered roller bearing system, combined with high-performance grease and a heavy-duty hub structure designed to manage radial, axial, and cornering loads while minimizing unnecessary friction and heat.

The proprietary bearing and hub structure is engineered to reduce hub-face deflection under load. Maintaining a more stable hub face helps support tighter steering response, consistent braking performance, improved wheel control, and long-term bearing durability.

Grade 10.9 cold-formed wheel studs provide the strength required for heavy-duty applications, while zinc plating helps protect the hardware against corrosion caused by moisture, road salt, and harsh operating environments.

The AX515208 installs as a complete bolt-in hub and bearing assembly and fits either the front driver or passenger side. No modification to the steering knuckle or suspension is required when installed on the correct application.

Unlike earlier GM hub assemblies, the 2020–2026 GM HD platform locates the ABS wheel-speed sensor in the steering knuckle. During installation, simply retain and reuse the truck's existing sensor and wiring.

Whether your truck spends its life pulling trailers, hauling equipment, running oversized tires, working every day, or exploring rough terrain, the AX515208 is built to provide the strength, precision, and longevity expected from an Axiom Supply wheel bearing assembly.
