A premium build quality, lightweight, aluminum performance radiator for any budget. Furnace-brazed construction is more durable than epoxy and gasket construction. Black epoxy painted finish doesn't inhibit thermal transfer of radiator. Double pass style Compatible with Chevy 1.5-inch passenger side upper inlet, and 1.75-inch passenger side lower outlet. Two rows of 1-inch aluminum tubes cool better than 5 rows of traditional copper tubes. Double pass design lowers coolant temperatures 10-20 degrees with 2.25-inch core. Dense fin structure improves airflow and adds rigidity to radiator core. Billet aluminum filler neck guarantees a long-lasting seal under high pressures. Widths (outside tank-to-outside tank) of 22, 24, 26, 28, or 31-inch available. All radiator widths are 19 inches tall to fit a variety of street and race applications. Efficient, yet simple single-pass crossflow design with 2.25-inch core thickness. Basic design for DIY universal fit applications, with the focus on engine cooling. Radiator mounting brackets, insulators, radiator cap, and shroud sold separately. Performance Under Pressure, Lap After Lap, Mile After Mile Our line of universal crossflow aluminum Compatible with Chevy radiators makes it easy for budget-minded racers to get a professional-quality, no compromises aluminum racing radiator. Constructed of lightweight, 100 percent aluminum, each radiator assembly is fully furnace brazed for maximum durability and performance. Unlike lower cost or OEM radiators, there are no epoxy and gaskets used in the radiator's construction here! Epoxy acts as an insulator, causing radiators to heat unevenly, and this stress combined with the vibration from racing can cause epoxy seals to crack and leak or separate over time. Furnace brazing minimizes fatigue from the rapid heating and cooling cycles
