Upgrade your C4, C5, or C6 Corvette cooling system with a Direct Fit Aluminum Radiator:

With a 100% stock 1984-2009 Corvette, the factory radiator will work efficient enough to keep the car running cool. As soon as you begin modifying your Corvette, you are going to push the factory radiator beyond its limits. The reason for radiator failures in modified Corvettes is a result of the single row core design. The end tanks were made of plastic and held in place with small crimp tabs and a neoprene rubber gasket was used to seal the tanks to the core. Frequent end tank failures and gasket leaks are just a few of the common problems associated with factory radiators installed in modified Corvettes. For complete assurance that your next radiator will not fail, consider a Direct Fit Aluminum Radiator. They feature press formed end tanks that are tig welded directly to the double row core, providing a permanent seal.

Zip Corvette offers the best Direct Fit Radiators on the market for C4, C5, & C6 Corvettes. Our Corvette Direct Fit Aluminum Radiators are just what the name implies; a direct fit. Many companies offer replacement Corvette radiators that are considered “direct fit”, but in fact, most require some alterations. True Direct Fit radiators are designed to install into the stock mounting and use the factory connections without any modifications or adapters. Each Direct Fit Radiator starts with a USA made core that is furnace brazed in a force nitrogen furnace. They feature two rows of 1″ cooling tubes (which will help double the cooling capacity of stock radiators), a serpentine fin and are epoxy free. Each Direct Fit tank is manually tig welded by expert craftsmen, providing the ultimate in strength and appearance.

From the earliest C4 to the latest C6, Zip has a Direct Fit Aluminum Radiator to match your Corvette. If you would like to install a Direct Fit Radiator but you want to keep your Corvette looking as original as possible, then simply have the radiator coated with ”Black Ice”. This Black Ice paint is applied to the outer surfaces of the radiator only, so the cooling tubes and any other components inside the fin material are not affected. Tests show that the Black Ice Coat will not disrupt the cooling process therefore allowing the Direct Fit Radiator to continue to out-perform all of its competition.
