Trimline Under Dash Louver Assembly

The Trimline Under Dash Louver Assembly by Vintage Air is a precision climate control component engineered for custom and classic vehicle builds. This assembly manages air distribution beneath the dashboard, directing conditioned air where it's needed most in your cabin. Whether you're restoring a muscle car, hot rod, or modern classic, this louver system ensures your air conditioning or heating system operates at peak efficiency without visible ducting running through your interior.

Built with the meticulous engineering Vintage Air is known for, the Trimline Under Dash Louver Assembly features a low-profile design that integrates seamlessly into tight dashboard spaces. At 32.85 inches in length with compact cross-section dimensions of 4.6 by 3.8 inches, it fits snugly behind trim panels and under existing dash structures while maintaining full airflow capacity. The lightweight construction—just 1.29 lbs—minimizes additional weight without sacrificing durability, making it ideal for performance-oriented restorations where every pound matters.

Technicians and enthusiasts choose this assembly when upgrading vintage HVAC systems or integrating modern climate control into classic interiors. The louver design allows adjustable air distribution, letting you control cabin temperature zones independently—a critical feature in vehicles with longer cabins or unconventional interior layouts. Installation pairs seamlessly with Vintage Air's complete under-dash kits and can be adapted to most American muscle cars, imports, and custom builds from the 1960s forward. For the serious modifier or restoration shop seeking OEM-quality air management without visible ductwork, this assembly delivers professional results.
