As with many low riding vehicles, C4 Corvettes are prone to getting cracks and chips in the lower air dam. Though most of the damage goes unnoticed it can have a direct effect on the performance of your Corvette’s Cooling System (http://www.zip-products.com/Zip/dept.asp?dept_id=3796).

The purpose of a C4 Corvette Lower Air Dam (http://www.zip-products.com/Zip/dept.asp?dept_id=272) is to direct air flow into the radiator cavity which begins the process of cooling your Corvette’s engine. If the first stage of the cooling process is interrupted by a cracked or chipped lower air dam the engine will not perform like it should. The reason for this is simple; lower air dams are designed a specific way causing the air flow to move smoothly into your Corvette’s engine. As many of us know; more cool, smooth air means more horsepower. Without a correct lower air dam less air will be directed into the engine ultimately leading to horsepower decreases.
At Zip Corvette we have everything needed to replace the lower air dams for all C4 Corvettes. Our 1984-1990 reproduction air dam kits are available in both the first and second designs. The first design air dams came without stiffening ribs and were used on 1984-85E and 1987-90 W/O Z51 Corvettes. The second design air dams came with stiffening ribs and were originally used on 1985L-86 and 1987-90 w/Z51 Corvettes. All 1991-1996 Corvettes used the same lower air dams.
When replacing your Corvette’s Lower Air Dams (http://www.zip-products.com/Zip/dept.asp?dept_id=272) take notice of the lower outer retainers, the lower center retainer, and the air dam mounting hardware. If any of these components look a little beat up we have reproduction retainers and hardware kits to mount original style air dams on 1984-1996 Corvettes.
