60-62 GM Truck Low Tunne l Full Insulation Kit

The 60-62 GM Truck Low Tunnel Full Insulation Kit from FLATLINE BARRIERS is designed for classic Chevy and GMC truck owners seeking enhanced sound deadening and thermal protection in the transmission tunnel area. This kit addresses a common issue in vintage GM truck interiors, where the low tunnel section lacks factory insulation, allowing transmission heat and road noise to infiltrate the cab.

Utilizing closed-cell foam and barrier material, this full insulation kit is specifically engineered to fit the low tunnel geometry of first-generation square-body Chevy trucks. The custom-cut pattern ensures a precise fit, making installation straightforward with pre-scored sections that align with factory contours. This insulation kit aims to improve cabin comfort during extended drives.

Restoration enthusiasts and classic truck builders will find significant benefits from this insulation kit, whether restoring a stock 1960–1962 Chevrolet C10 or upgrading to modern performance standards. Its lightweight design, at 6.83 pounds, adds minimal weight while providing essential acoustic and thermal performance enhancements.
