Upgrade your cooling system with Allstar Performance Dual Pass Aluminum Radiators, designed for maximum heat dissipation and durability in racing and street performance builds. Each unit features a fully welded all-aluminum construction with two rows of 1-inch furnace-brazed tubes and a billet aluminum filler neck with a removable overflow fitting for superior reliability.

The dual-pass design routes coolant through the top half and back through the lower half, doubling cooling efficiency compared to traditional radiators. A 1-3/4" angled lower outlet makes these radiators ideal for applications where the unit is mounted low in the chassis, and the universal 1-5/8"-12 ORB inlet allows for multiple fitting options (sold separately).

Built to handle the demands of motorsports and high-performance street use, these radiators are available in multiple sizes to suit your setup. For best results, use with a radiator cap rated at 28 psi or less.
