The Allstar Performance Dual Pass Radiator (ALL30035) is designed for serious cooling performance in motorsports and street builds. This fully welded aluminum radiator features a dual-pass crossflow design that directs coolant through the core twice—significantly increasing heat dissipation compared to traditional single-pass units.
Equipped with two rows of 1" wide furnace-brazed tubes and a billet aluminum filler neck with removable overflow fitting, it is built for durability and efficiency. The inlet accommodates a wide range of fitting types, and the lower outlet is angled for installations requiring low chassis mounting.
