Fitment, Shipping & Product Support
The Axiom Wheel Speed Sensor (SKU AX19300584) is an OEM-grade direct-fit replacement wheel speed sensor for 2001–2007 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD trucks in Classic body style (GMT800 platform). The wheel speed sensor delivers precise wheel-speed data to the ABS module, traction control system, and stability control system. A failed or corroded sensor causes ABS warning lights, erratic braking behavior, traction control faults, and disabled stability control. This sensor restores accurate signal output and correct system operation. Direct plug-and-play connector — no wiring modification required. Corrosion-resistant housing for heavy-duty truck environments.

GM HD Wheel Speed Sensor Platform Guide
| Platform | Years | SKU |
|---|---|---|
| Classic Body (GMT800) (this listing) | 2001–2007 | AX19300584 |
| New Body Style (GMT900) | 2007.5–2010 | AX22873507 |
| K2XX/T1XX | 2011 and newer | Different sensor — confirm separately |
Symptoms of a Failed Wheel Speed Sensor
- ABS warning light illuminated
- Traction control or stability control warning light illuminated
- ABS activating at low speeds or on dry pavement
- Erratic or pulsating brake pedal feel
- Speedometer or odometer inaccuracy (on some configurations)
Installation Notes
- Body style confirmation required. Confirm your 2007 truck is the Classic body style (GMT800) before ordering. The 2007 model year includes both Classic (GMT800) and New Body (GMT900) trucks — they use different sensors with incompatible connectors.
- Replace in pairs. When diagnosing ABS faults, replace sensors in pairs (both front or both rear) for best results. A marginal sensor on the opposite side can cause continued ABS faults even after replacing the failed unit.
- Connector inspection. Inspect the wiring harness connector for corrosion, broken pins, or damaged wiring before installation. A corroded connector will cause signal faults even with a new sensor.
- Torque specs. Torque sensor mounting hardware to OEM specification for 2001–2007 GM 2500HD/3500HD. Do not overtorque — sensor housing can crack.
- Code clearing. After installation, clear ABS and traction control fault codes with a scan tool. Drive above 15 mph to allow the ABS module to relearn wheel speed signal and confirm the warning light clears.

Common Questions
How do I know if my 2007 truck is Classic or New Body?
The 2007 model year was a split production year. Classic Body (GMT800) trucks were built through early 2007, before the New Body (GMT900) launched mid-year. Check your build date or VIN, or confirm with us before ordering — the connectors are not interchangeable between the two body styles.
Do I need to replace both sensors on an axle, or just the failed one?
For best results, replace both sensors on the same axle (both front or both rear) when diagnosing ABS faults. A marginal sensor on the opposite side can continue causing faults even after the failed one is replaced.
Does this fit my 2008 Sierra 2500HD?
No. The 2008+ generation uses a different sensor and connector entirely.
Do I need a scan tool after installing this?
Yes. Clear ABS and traction control fault codes with a scan tool after installation, then drive above 15 mph to let the ABS module relearn the wheel speed signal and confirm warning lights clear.
The Obsidian Take
The AX19300584 is for the 2001-2007 Silverado/Sierra 2500HD/3500HD Classic Body (GMT800) owner dealing with ABS, traction control, or stability control warning lights traced to a failed wheel speed sensor. OEM-grade signal accuracy, plug-and-play connector, corrosion-resistant housing.
The one check that matters most: confirm your 2007 truck is specifically Classic Body, not New Body — this was a genuine split production year, and the two body styles use different sensors with incompatible connectors.
Non-Returnable Notice: Once installed, this unit is non-returnable. Confirm body style (Classic GMT800 vs. New Body GMT900) before ordering.
