A radiator is a heat exchanger. It’s there that the heat absorbed by the coolant in your engine is transferred to the air, enabling the engine to operate within its optimal temperature range. But if you modify the engine, with high compression, forced induction or other means, it will make more horsepower but also create much more heat in the process, more heat than the factory cooling system was engineered to handle. To keep your engine cool, make sure a performance radiator is included in your mods.

Performance radiators are an upgrade over factory units in several ways. They’re constructed from lightweight aluminum, and although aluminum is used for the majority of today’s OE radiators, they often have plastic tanks, which can leak. Our aluminum radiators have aluminum tanks brazed or welded to the core. And while copper has better thermal conductivity, it’s not as strong as aluminum, so copper radiators have to be made thicker and heavier, which negates the material’s heat conducting capabilities.

In addition to superior materials our performance radiators incorporate advanced design gained from knowledge of thermal and fluid dynamics. While specific features will vary according to radiator application, in general performance radiators have larger and/or more tubes than factory radiators to increase coolant flow, along with greater fin density to increase the surface area to which coolant and air are exposed, which results in better heat transfer and a cooler running engine. We offer both crossflow and downflow radiators in direct fit versions that will bolt on in place of your OE radiator, as well as universal radiators for custom applications.

Our direct fit performance radiators will substantially improve cooling, and come with OE size inlets and outlets in the original factory locations, and mounting brackets that provide a hassle-free installation. When even greater cooling capability is needed, direct fit radiators with larger cores are available for some applications, but may require slight modifications for mounting. Our universal radiators are ideal for street rods, custom cars, and race cars, and we offer radiators designed specifically for drag racing and circle track. Many of our radiators are available as combos that include one or two electric cooling fans and all the necessary mounting hardware.

A component as large as a radiator that occupies such a prominent location in the engine bay has to look right on your hot rod, and our performance radiators fill the bill, but if you’re looking for the ultimate finishing touch for under the hood, consider our mirror polished radiators that include a polished recovery tank and radiator cap. In addition to our performance radiators, we also offer many related products including custom fan shrouds for single and dual fans and diversion plates for select applications, to ensure air is properly channeled through the radiator for maximum cooling, and radiator caps, available in custom finishes or with integral temperature gauges.

    Hot Under The Hood? Performance Cooling Fans Chase Away Excess Heat
    Auxiliary fans are great for providing a boost to your vehicle's original cooling system if you've encountered overheating conditions. For those who live in climates that see high temperature and humidity, excessively high coolant temperatures can be a major problem - one that will not go away if ignored. Aluminum engine blocks and cylinder heads found on most of today's cars are much more sensitive to overheating than traditional engine blocks made of iron. All it takes is one stretch of time with parts reaching excessively high temperatures to cause permanent metal warpage, leaks, and damage to a myriad of moving parts.

    Servicing Your Vehicle's Cooling System
    Everyone knows that your vehicle's engine needs its oil and filter changed at regular intervals. Most folks also know that there are other items which need regular servicing and replacement, such as the air and fuel filters. But what about the cooling system? The fact is, a modern vehicle's cooling system does such a great job at preventing an engine from overheating that we all but ignore it. The reality is, all vehicle manufacturers have a recommended interval when the coolant should be replaced.
