DEI Custom-Cut Interior Insulation kits for 1988-98 GM Extended-Cab Pickups

On the heels of its successful Interior Insulation Kit release for 1973-’87 Chevrolet/GMC regular-cab truck models, Design Engineering, Inc. is following up with a custom-cut solution specifically for 1988-’98 extended-cab GM pickups.

Using a combination of proven 2mm damping material and Under Carpet Lite to control heat and block unwanted road, tire and engine noise, the kits are an easy, affordable way to cruise your classic truck in style.

“Pre-cut Interior Insulation Kits ensure the correct material to cover specific interior areas including floors, firewalls, headliners and more,” says Mike Buca of DEI. “Everyone knows how popular these older pickups are with consumers, and now DEI is making the ride even more enjoyable.”

For the quietest, most comfortable interior, first put down the damping kit to eliminate noise and vibration, and then follow with an insulation kit for superior thermal protection. Add the roof-specific part numbers for a total cab makeover.

DEI insulation kits are CNC-cut for a precise fit and easy installation:
