Front ABS Wheel Speed Sensor Pair (Left + Right) Replaces 15037208 19181873 19300584 for Chevy Silverado Tahoe, GMC Sierra Yukon, Cadillac Escalade, Hummer H2

Replace both front sensors in one job — and save. This set includes two front ABS wheel speed sensors (left + right) for Chevrolet, GMC, Cadillac and Hummer trucks and SUVs, replacing GM numbers 15037208, 15112378, 15112379, 15233108, 15716191, 19181872, 19181873 and 19300584. Both front corners use the same sensor, so doing them as a pair keeps brake response even and saves you a second disassembly later.

What you get: 2 × front ABS wheel speed sensor, each with its wiring harness.

Drivetrain: Fits both 2WD and 4WD models. For 2005 and later Silverado / Sierra 2500 HD & 3500 (8-lug HD platform), please match your original part number before ordering — message us your VIN and we'll verify for you.

Why Replace Both Sides

• Both front sensors see identical road conditions and corrosion — if one has failed, the other is usually close behind
• Avoids the "ABS light came back a month later" second repair
• Costs less than buying two sensors separately
• One jack-up, one set of tools, both wheels done

Installation (about 1 hour per side)

1. Loosen the lug nuts, raise and support the vehicle, remove the wheel.
2. Unplug the sensor connector and remove the mounting bolt.
3. Pull the old sensor out and clean the mounting hole and hub surface.
4. Install the new sensor, routing the harness exactly like the original.
5. Reconnect, refit the wheel, torque the lug nuts to factory spec.
6. Repeat on the other side, then drive a short distance — the ABS light should clear on its own.

FAQ

Are these two different sensors?
No — on these vehicles the front left and front right use the same part number, so you receive two identical sensors, one for each side.

Can I buy just one side?
Yes, see our single-sensor listing for the same part.

My truck takes 19300584 — same part?
Yes — 19300584 is GM's current service number for this sensor and replaces all the older numbers in the list.

Will it fit my 4WD truck?
Yes — fits both 2WD and 4WD. Message us your VIN if you'd like confirmation.

Do I need a scan tool?
No. The ABS module re-learns the signal on the next drive.
