Dual Pass Radiator 19x26 1 Row Lightweight Black

The Dual Pass Radiator 19x26 1 Row Lightweight Black from Allstar Performance is engineered for high-performance automotive cooling systems where weight savings and efficient heat dissipation are critical. Built for serious enthusiasts and mechanics upgrading street machines, race cars, and custom builds, this single-row radiator delivers dependable cooling while minimizing overall vehicle weight—a key advantage in both performance tuning and fuel economy applications. The dual-pass design ensures superior coolant flow management compared to traditional single-pass units, making it ideal for builds where engine bay space is constrained or weight reduction is a priority.

This lightweight black radiator measures 19 inches wide by 26 inches tall with a single-row aluminum core, optimized for efficient heat transfer across a compact footprint. The dual-pass flow path—where coolant enters and exits on the same side—maximizes residence time in the core while reducing turbulence, resulting in more uniform temperature management across the entire radiator face. At just 14.03 pounds, the unit's minimal weight is achieved through quality aluminum construction without sacrificing structural integrity or cooling capacity, making it especially valuable in bracket racing, street rod applications, and engine swaps where every pound matters. The all-black finish provides a professional appearance that complements modern engine bay aesthetics.

This radiator suits builders working with vintage platforms, compact engine bays, or modern muscle cars requiring efficient cooling in a tight package. Installation typically involves standard hose connections compatible with common cooling systems; verify your existing inlet and outlet hose sizes and radiator mounting provisions before ordering. The lightweight design pairs well with aluminum water pumps, electric cooling fans, and modern thermostat housings to achieve balanced thermal performance in custom and performance applications. Mechanics frequently specify this unit for street/strip builds where reliable cooling at highway speeds and track runs is non-negotiable.
