When you invest in a heavy-duty GM truck with advanced safety features like Blind Zone/Blind Spot Monitoring, you expect full functionality no matter how you upfit your vehicle. Yet when most service body builders change out the bed, those driver-assist systems can be lost or disabled — compromising safety and value.
What Is GM’s Blind Spot Monitoring and Safety Package?
Modern GM trucks like the Chevy Silverado and GMC Sierra use radar and sensor-based systems to help you avoid collisions when changing lanes or merging. These features — known commonly as Lane Change Alert with Side Blind Zone Alert and often bundled with packages that include rear cross-traffic and park assist — monitor areas you can’t see in your mirrors and alert you when a vehicle enters your blind spot.bommaritochevysouth.com+1
While these safety systems are designed around the factory pickup bed and bumper, service bodies pose a challenge. Without the right engineering and integration, those sensors can become unusable once the original pickup bed is removed.
The Diamond Difference: Full Blind Spot Functionality With Your New Service Body
On select builds — like this ST-Eliminator service body shown on a 2025 Chevy 3500 — we relocate and integrate the BLISS/blind spot system and other factory sensors right onto the new service body.diamondtruckbody.com
That means:
Your truck’s factory blind-spot alerts still work even after installing a service body
Sensors are carefully repositioned and calibrated so the system’s performance stays intact
Rear cameras and sensors are relocated for a clean, functional install that preserves safety
This isn’t a guess — it’s engineered and tested by our team
This level of integration requires skill and experience — and it’s something we don’t see offered anywhere else in the work truck industry.

Why It Matters for Fleets and Contractors
For commercial drivers, safety technology isn’t just about convenience — it’s about protecting your team and your assets on the road. Blind spot warnings reduce lane-change collisions and driver stress, especially in heavy traffic or tight jobsite conditions.
By transferring your GM truck’s safety sensors to a rugged service body, you keep features that:
improve visibility
reduce insurance risk
increase resale value
enhance driver confidence
That’s real value — and it’s part of why so many contractors and fleet managers choose Diamond for their truck builds.
