Alum DBL Pass 1.25in 19in x 27.5 GM Alum

The Alum DBL Pass 1.25in 19in x 27.5 GM Alum is a dual-pass aluminum radiator designed for General Motors applications that require efficient thermal management in various environments, including street, strip, and performance settings. This product is ideal for automotive enthusiasts and mechanics who need reliable cooling performance under sustained loads, whether for stock or modified engines.

Constructed from lightweight aluminum, this radiator features a 1.25-inch inlet/outlet neck configuration that maximizes heat rejection while minimizing weight. The dual-pass design enhances coolant circulation, effectively reducing hot spots and maintaining consistent operating temperatures during aggressive driving or towing. Its internal baffle system optimizes coolant flow for superior heat transfer rates.

This radiator is compatible with most full-size and mid-size GM trucks, SUVs, and passenger vehicles from the 1960s to modern platforms, making it an excellent choice for restorations, engine swaps, and performance builds where OEM cooling capacity may be insufficient. Installation is straightforward, requiring standard hose clamps and mounting hardware.
