Speedway Motors Universal Aluminum Crossflow Radiator for Chevy Applications with High Pressure 29–31 PSI Cap, Lightweight Furnace-Brazed 2-Row 1-Inch Tube Core, 31 Inch Width

Our line of universal crossflow aluminum Compatible with Chevy radiators make 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 single pass design uses two rows of 1” wide aluminum tubes which have more surface area than copper radiators, cooling the same as five rows of copper tubes. 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. Features A professional quality, lightweight, all-aluminum racing radiator at any budget. Furnace-brazed construction is more durable and improves performance vs. epoxy and gasket construction

• High Efficiency Cooling: Features two rows of 1-inch aluminum tubes, providing heat dissipation comparable to five-row copper radiators for improved temperature control.
• Durable Furnace-Brazed Design: All-aluminum construction eliminates epoxy and gasket joints to enhance strength, heat transfer consistency, and long-term reliability.
• Performance-Ready Radiator Cap: Includes a 29–31 PSI high pressure cap that raises the coolant boiling point and helps reduce overheating in demanding conditions.
• Optimized Crossflow Layout: Single-pass, crossflow configuration with a 2.25-inch core increases airflow efficiency and cooling surface area.
• Universal Compatible with Chevy Configuration: Designed with 1.5-inch driver-side upper inlet and 1.75-inch passenger-side lower outlet to fit a wide range of Compatible with Chevrolet engine setups.
