    Zip Corvettes Direct Fit Corvette aluminum radiators are the finest high performance aluminum radiators available for your Corvette. Each radiator is designed to fit into the factory mounting, without any modifications. This true "Direct Fit" aluminum radiator is designed for 1973-1976 350/454 4-speed Corvettes. Featuring the correct 27.5" core, factory type upper channels, stock hose connections, and press formed tanks.

    Direct Fit radiators are completely manufactured and assembled right here in the United States. Along with that comes the quality that you would expect from a company that takes pride in turning out Corvette radiators. Each Direct Fit Corvette radiator begins life as an aluminum core with two 1" wide cooling tubes. This configuration more than doubles the cooling capacity by increasing the "tube to fin" contact area over the stock 4-row copper radiator. This can only be achieved with an aluminum radiator since the aluminum material does not dramatically affect the radiators weight. Tanks are press formed and inlet/outlets are correctly configured for a drop-in installation. Each core is then brazed in a controlled atmosphere furnace; which eliminates the need for epoxy, ensuring leak free, and trouble free service for many years to come. Direct Fit radiators include GM style top-hat channel and factory style tanks for a radiator that not only drops-in place but also looks OEM.

    Dewitt's has also solved the problem of ill fitting radiator cushions and support brackets. Direct Fit radiator can be installed with a newly designed rubber mount cushion that has been molded to fit both the GM "U" style radiator support bracket and the "top-hat" channel found on Direct Fit radiators. These cushions provide for a perfect mount - much better than stock rubber. To complete the installation of your Direct Fit radiator - Zip suggests purchasing (4) molded rubber cushions ( Zip # RA-240). Check out Zip # RA-240 for a picture of the molded cushion that fits the Direct Fit radiator like a glove!

    Direct Fit radiators are available in your choice of natural or black ice coated. Black Ice is an OE-style epoxy finish designed to turn an aluminum radiator into a factory look-alike without affecting cooling performance. Specify radiator finish when ordering. Additional costs will be incurred for black ice coated.

    Dewitts Direct Fit aluminum radiators are warrantied to be free from defects in materials and workmanship for as long as you own the Corvette in which it was originally installed. This warranty is extended only to the first retail purchaser of any such radiator. Proof of purchase must be provided from an authorized dealer. If the radiator is used in any racing application this warranty is considered null and void. Radiators used without an adequate proportion of premium quality antifreeze coolant and distilled water are not covered by this warranty. DRI radiators require a correct proportion of quality coolant, which contains aluminum corrosion inhibitors in the formula and distilled water. All Corvette cooling systems must include a radiator pressure cap with the proper pressure rating. Distilled water and premium antifreeze must be used with all Corvette aluminum radiators!
