Vehicle-specific dash kit for GM trucks

The Metra 87-99-3052 is a single-DIN or 2-shaft installation kit designed for 1973 through 1987 Chevrolet Blazers and Pickups as well as GMC Suburbans and Pickups. It provides the structural support the dashboard needs when fitting a DIN radio. The kit is built for older GM trucks where the original dash cannot hold a modern head unit on its own. Installers working on these specific models use it to secure the radio without modifying the factory opening.

Thermals noise and power draw

As a passive mounting accessory the kit generates no heat, produces no noise and draws no electrical power. It simply reinforces the dashboard structure around the radio cavity. Normal use therefore adds nothing to the vehicle's thermal load or electrical system. The only physical demand is the hardware tightening against the dash during installation.

Build quality and mounting implications

The kit is moulded to match the contours of the listed Chevrolet and GMC trucks so the radio sits flush with the surrounding dash panels. Included brackets and fasteners lock the head unit in place, preventing vibration or shifting over rough roads. Because it accepts both single-DIN and 2-shaft radios the same kit covers two common mounting standards. No wiring harnesses or electronic interfaces are included; those must be sourced separately for the chosen radio.
