Race Pro Radiator 19 x 24 LS Configuration

The Race Pro Radiator 19 x 24 LS Configuration from Northern Radiator is purpose-built for LS engine swaps and high-performance street/strip applications where OEM cooling capacity falls short. Whether you're running a carbureted LS in a classic chassis or a fuel-injected LSx in a modern platform, this aluminum radiator delivers the thermal management required to keep peak horsepower and torque consistent under sustained load. Serious builders and weekend warriors alike rely on Northern Radiator's Race Pro series when factory units can't handle the demands of modified engines pushing aggressive timing and elevated boost.

This 19 x 24 inch core radiator features optimized fin density and tube design that maximizes heat rejection while maintaining efficient coolant flow—critical for sustained high-RPM operation and towing duty. The LS configuration mounting provisions align with GM LS engine bay layouts, reducing fabrication time and ensuring proper fitment in both original and swapped applications. Weighing 16 lbs with overall dimensions of 23.2 x 7 x 27.4 inches, the unit balances durability and weight efficiency. All-aluminum construction resists corrosion and withstands higher static pressures than copper-brass designs, making it ideal for pressurized cooling systems running electric fans or belt-driven mechanical units.

Engine builders upgrading LS-powered vehicles—from full restorations to complete swaps—benefit from Race Pro's reputation for reliability and heat-shedding performance. Installation is straightforward on LS-based platforms; confirm radiator hose routing and upper/lower tank orientation before final mounting to avoid clearance conflicts with adjacent components. Pair this radiator with a quality thermostat, hose clamps rated for high pressure, and a properly sized cooling fan for optimal results. Suitable for street, strip, and light competition use where consistent coolant temperatures support peak engine efficiency.
