C4 Corvettes are susceptible to lower air dam damage due to parking lot stops and road curbs. Damaged or missing lower spoilers will not direct air flow needed into your C4 Corvette's radiator, robbing your Corvette of power through an improperly cooled engine. Zip has new reproduction lower air dams to help return your 1991-1996 Corvette to its original condition. Reproduction front spoiler kit includes both LH and RH side plus the center spoiler. 1st design without stiffening ribs. Requires fastener kit ZSF-471 to mount.
