Detailed Description

Standard Ignition ALS3638 is an ABS wheel speed sensor made for the rear right position on Ram 3500 trucks from 2019 through 2025. It is used to report wheel speed to the ABS control system, helping the brake electronics interpret wheel rotation accurately during braking events. The sensor uses a bolt-mount installation style, a 2-terminal connection, and a 57.25-inch harness for proper routing on the wheel end of the vehicle. If you are replacing a failed rear wheel sensor on a Ram 3500, ALS3638 provides the correct fitment and connector style for this application.

Common Issues This Part May Address

• ABS warning light caused by a failed rear wheel speed sensor
• Loss of wheel speed signal at the rear right wheel
• Brake system fault codes related to wheel speed input
• Intermittent ABS operation from damaged sensor wiring or connector wear
• Incorrect sensor readings from corrosion or physical sensor damage

Installation Notes and Tips

Verify rear right fitment before installation on 2019-2025 Ram 3500 models. Inspect the mounting surface, bolt holes, and connector condition before transferring the new sensor into place. Route the harness away from moving suspension and wheel components, and confirm the connector seats fully after installation. This part cross-references 534026 for the same application.
