MG GS/ZS ABS Wheel Speed Sensor With Wire Harness

This sensor is designed for MG GS models from 2015 onwards, so your 2020 GS is compatible. You'll need to confirm whether you need a front or rear sensor, and if your GS is 2WD or 4WD, as rear fitment varies between these drivetrains.

The MG GS rear sensors come in three SKU variants: left and right options for 2WD models (which require separate left/right sensors), and a single 4WD variant that works regardless of side. If your GS is 2WD, you'll need to specify left or right when ordering. If it's 4WD, a single SKU covers both rear positions.

Yes, this sensor is compatible with MG ZS models from 2017 onwards, so your 2018 ZS will fit. We offer two SKU variants for the ZS: one for front wheel and one for rear wheel, so select based on which position you're replacing.

The package includes the ABS wheel speed sensor, integrated wire harness, mounting bracket, and a hardware kit with bolts and clips. For installation, you'll need standard tools to unbolt the old sensor and tighten the new one to manufacturer specifications, plus a socket set to disconnect the battery terminal.

Installation is straightforward with the pre-assembled wire harness and plug-and-play connector, typically taking 30–60 minutes per sensor depending on wheel access and corrosion on the mounting surface. The step-by-step process includes disconnecting the battery, removing the old sensor, cleaning the mounting area, installing the new sensor, and reconnecting the battery to verify ABS function.

The sensor features a high-sensitivity magnetic pickup design engineered to withstand extreme temperatures and road contaminants for long-term reliability. The OEM-quality construction ensures it maintains consistent anti-lock braking system performance over time, and the integrated wire harness is designed to resist corrosion and electrical degradation in harsh brake system environments.

This is an OEM-quality replacement part designed to restore your ABS system to factory specifications without modifications to your vehicle. For clarity on how replacement parts affect your specific warranty, we recommend contacting your MG dealer or consulting your vehicle's warranty documentation, as policies vary by region and model year.
