Can you add blind-spot monitoring to Silverado?
Yes. You can add blind-spot monitoring to a Chevrolet Silverado either through a factory-installed option on newer models or by installing an aftermarket system. The available path depends on your model year, trim level, and whether you’re willing to pursue dealer enablement or third-party installation.
Blind-spot monitoring on the Silverado is typically marketed as Lane Change Alert with Side Blind Zone Alert, often bundled with other safety features. Availability varies by generation, trim, and whether the truck has the necessary hardware; this article lays out factory options, aftermarket paths, and installation considerations so you can choose the best route for your Silverado.
Factory-installed blind-spot monitoring
The Silverado’s blind-spot feature is usually offered as part of a Safety/Driver Assist package and is available on many recent trims. The core feature is Lane Change Alert with Side Blind Zone Alert (SBA), which uses sensors in the rear corners to warn you of vehicles in your blind zones; this is commonly paired with Rear Cross Traffic Alert (RCTA).
- On newer generations (roughly 2017–present), Lane Change Alert with Side Blind Zone Alert is typically available with the Safety Package or Driver Assist options on appropriate trims and body configurations.
- Rear Cross Traffic Alert is often bundled with SBA as part of the same package, enhancing awareness when backing out of parking spots or driveways.
- Availability can vary by trim level, cab configuration (Regular, Double, Crew), bed length, and optional technology packages; some models may require a software update or hardware sensors to be installed.
In short, if you own a relatively new Silverado, check the Safety/Driver Assistance packages for SBA and RCTA; dealers can sometimes enable features via software if the hardware is present.
Aftermarket blind-spot monitoring options
If your Silverado is older or your trim lacks factory SBA, aftermarket systems offer a viable alternative. These range from mirror-based units to radar sensor kits that install in the bumper or around the vehicle and connect to a display or your existing dash indicators.
- Mirror-based kits: Replace or augment the existing mirrors with a unit that includes integrated blind-spot indicators and turn signals; typically easier to install but may have limited integration with other vehicle systems.
- Bumper-mounted radar kits: Place radar sensors in the rear bumper/fascia, with a control module and an in-cabin display or indicator lights; often requires professional calibration.
- Display options and integration: Some kits offer standalone displays, while others integrate with the vehicle’s existing indicators; reliability and compatibility vary by brand and model year.
Costs vary widely: basic aftermarket hardware can start around $50–$150 for DIY installations, while professional installation with a more integrated display can run from $300 to $800 or more depending on the system and vehicle compatibility.
Bottom line: aftermarket systems provide flexibility for older Silverados or trims without SBA, but they may not perfectly mimic OEM functionality or interaction with other driver-assistance features.
Installation considerations and safety
Choosing between factory retrofit and aftermarket installation involves warranty implications, system integration, and calibration requirements. Factory-enabled SBA is designed to work seamlessly with other GM safety features and often includes dealer support and software updates. Aftermarket installations can deliver the functionality you want, but may require specialized installation, calibration, and may void certain warranties if not performed properly.
- Assess your Silverado’s model year, trim, and whether the hardware for SBA is present or needs to be added.
- Decide between a dealer-installed factory option (preferred for integration and warranty) and an aftermarket solution (more flexible, potentially cheaper for older models).
- If choosing aftermarket, select a reputable brand with vehicle-specific fitment and professional installation to ensure correct sensor alignment and calibration.
- Have the system tested after installation to verify accurate sensor readings, correct indicator operation, and proper cross-traffic alerts.
Overall, you can add blind-spot monitoring to a Silverado, but the best path depends on your model year, trim, and priorities for warranty coverage, integration with other safety features, and budget.
Summary
For many Silverado owners, the simplest route is to pursue the factory SBA option (Lane Change Alert with Side Blind Zone Alert) through a GM Safety/Driver Assist package on eligible trims. If your truck is older or lacks the hardware, aftermarket blind-spot monitoring systems provide workable alternatives, though they require careful selection and installation to ensure proper calibration and compatibility with other vehicle systems. Always verify exact availability for your specific model year and configuration before purchasing or installing any system.
