Replacement RD31080040 Front ABS Wheel Speed Sensor with Harness 2WD

The Replacement RD31080040 is a front ABS wheel speed sensor designed as a direct-fit OEM-quality replacement for Ram full-size pickup trucks. This sensor fits both the driver and passenger side (RH=LH) and is engineered specifically for 2WD applications. It includes the wiring harness for a complete, plug-and-play installation.

How It Works:

The ABS wheel speed sensor continuously monitors how fast each front wheel is spinning and transmits that data to the ABS control module. If the module detects a wheel is about to lock up during hard braking, it rapidly modulates brake pressure to that wheel, helping maintain steering control and preventing dangerous skidding.

Key Features:

• Direct OEM Replacement — engineered to match original equipment specifications for precise fit and function
• Includes Wiring Harness — complete sensor assembly with integrated harness for plug-and-play installation
• Dual-Side Fitment — single part number fits both driver (LH) and passenger (RH) front positions
• 2WD Applications — designed specifically for rear-wheel-drive Ram full-size pickups
• OE-Style Sealed Connector — protects against moisture, corrosion, and harsh under-vehicle conditions

Cross-Reference Part Numbers: 70790, 532691, 726707, 2411223, 2ABS2291, 5179964AA, 5S8492, ALS2242, AB2046, SS11588

Replacing a faulty ABS speed sensor will extinguish the ABS warning light and restore proper anti-lock braking function. After installation, any stored fault codes can be cleared with an OBD2 scanner or by briefly disconnecting the battery.
