Carbhub Rear ABS Wheel Speed Sensor Pair for 2007-2013 Chevrolet Silverado 1500 & GMC Sierra 1500, Size 10384745, Left and Right D

If your ABS warning light is on, your traction control is acting inconsistently, or the vehicle's braking feels less predictable, the rear wheel speed sensors are often the cause. This Carbhub two-piece kit includes left and right rear sensors engineered as direct-fit replacements for the factory units, designed to plug into existing wiring and mount in the original locations. Built to match OEM fitment and electrical specifications, the sensors make a straightforward repair without cutting or splicing harnesses.

How will these sensors affect ABS and traction performance?

Wheel speed sensors provide the wheel rotation data the ABS and traction-control modules rely on. Installing properly functioning sensors stops erroneous readings that trigger warning lights and can restore normal ABS modulation and stability control behavior.

• Eliminates false ABS/TC warning lights by returning accurate wheel-speed data.
• Prevents unintended ABS activation from incorrect sensor signals.
• Improves brake modulation and traction interventions under slippery conditions.

Do these sensors fit my truck and which part numbers do they replace?

These rear sensors are made to fit 2007–2013 Chevrolet Silverado 1500 and 2007–2013 GMC Sierra 1500 models. They are intended as direct OEM-style replacements for several common factory and aftermarket part numbers.

• Compatible with OE references: 20938121, 20763148, 10384745, 15872664.
• Also replaces aftermarket identifiers: ALS1757, SU9441, 5S7975, SS11518.
• Kit contains two sensors for rear left and rear right installation.

How difficult is installation and what tools are required?

These sensors are designed for straightforward, plug-and-play replacement using the vehicle’s existing mounting points and connector. Most installations can be completed with common hand tools without any wiring changes.

• Factory-style connector eliminates the need for splicing or adapters.
• Typical tools: socket set, screwdrivers, and a torque wrench for hub hardware.
• Expect minimal disassembly of wheel or brake components on most trucks.

What are the durability and quality details to expect?

Carbhub sensors are manufactured to meet electrical and environmental tolerances similar to original equipment. Materials and sealing are selected to resist road grime, moisture, and vibration that commonly degrade sensor performance over time.

• Sealed housings to guard against water and contaminants.
• Robust connector and wiring jacket for long-term reliability.
• Precision mounting points for secure, vibration-resistant fit.
