Built from premium-grade aluminum, this Severe Heavy Duty radiator is constructed to meet OEM form, fit, and function while delivering enhanced cooling performance under the most demanding conditions. Each unit is individually pressure tested and features cadmium-plated tubes inside and out to help prevent premature failure and extend product life.<\/p>\n<p>Unlike many aftermarket alternatives, OSC maintains OE integrity by utilizing stainless steel plate or copper and brass concentric coolers where originally equipped, never substituting with aluminum. A precision die-cut gasket ensures a secure, leak-free seal, while all necessary hardware, fittings, clamps, and bushings are included for a complete installation.<\/p>\n<p><span style=\"color: #ff0000;\"><strong>Beyond OE.
