Universal SBC Double Pass Radiator Kit w/Mechanical Fan, 24 Inch

Our line of universal Chevy radiators makes it easy for budget-minded racers to get a professional-quality, no compromises aluminum racing radiator. 

Performs Under Pressure

Constructed of lightweight, 100% aluminum, we furnace braze the radiator assembly for maximum durability and performance, no epoxy and gaskets here! Epoxy acts as an insulator, causing radiators to heat unevenly, and this stress combined with the vibration from racing can break epoxy seals and leak or separate over time. Furnace-brazing minimizes fatigue from the rapid heating and cooling cycles. Since all the metal parts are fused together with a metal joint, they conduct heat evenly between the tanks and the rest of the assembly, preventing uneven expansion between the fused pieces, keeping the joint strong. 

We welded a billet filler neck for a strong seal under high pressures that will outperform cast filler necks with an industry standard 1-5/8” inner cap diameter and a 1/8” NPT overflow port. 

Maximum Cooling Performance

Our double-pass design uses two rows of 1” wide aluminum tubes, cooling the same as five rows of copper tubes. The double-pass design flows the coolant twice through the radiator, allowing longer time in the airflow and lowering your coolant temperatures by 10-20 degrees. Learn more about how radiators work and selecting the proper radiator for your vehicle by reading our tech article. Radiator Cooling Performance.

A dense fin structure adds an additional layer of strength to the support tubes, better directs air flow and has more area to transfer heat. The core is 2.25”, a perfect balance of maximizing directed airflow and heat transfer. The cross-flow design allows the radiator cap to be mounted on the low-pressure (suction) side of the system, minimizing pressure on the neck assembly, especially in high-RPM usage. This radiator is built for one purpose, cooling your engine. No transmission cooler maximizes cooling efficiency.
