Standard Ignition ALS3446 ABS Wheel Speed Sensor - Rear

ABS Wheel Speed Sensor for Rear Applications

Standard Ignition ALS3446 is an ABS wheel speed sensor for rear wheel mounting on select Chevrolet Express 2500 and Express 3500 vans, as well as GMC Savana 2500 and Savana 3500 models. It uses a bolt-mount design with a female connector, male blade terminals, and an oval connector shape for a direct-style electrical connection.

This ABS wheel speed sensor is built for rear axle applications that require a wheel-mounted sensor without a harness or dust shield. Standard Ignition ALS3446 cross-references 533836 and ABS3446 for the same application.

• Brake control issues tied to missing wheel speed input
• Diagnostic trouble codes associated with rear ABS sensor performance

Installation Notes

Verify rear axle ratio and vehicle application before installation, especially on Chevrolet Express 3500 and GMC Savana 3500 models with 3.54 axle ratio notes. Confirm the connector style, terminal count, and bolt-mount location match the original sensor before replacing the part. Standard Ignition ALS3446 is a wheel-mounted sensor and does not include a harness, so inspect the vehicle wiring and connector condition during service.

Quality Assurance

Standard Ignition supplies replacement electrical and sensor components for service applications, and ALS3446 is listed with OE-style interchange references for the same rear ABS wheel speed sensor use.
