The fully threaded billet aluminum shock body sets ride height for the desired stance and helps fine-tune weight balance for improved handling, while the single adjustable valving dials in the ride. QA1's American-made lightweight high travel springs use fewer coils and a smaller wire diameter for increased travel, reduced unsprung weight and faster response. It installs as a bolt-in upgrade and is used in drag racing, street performance, autocross, road racing and street rod applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: front coil-over system (Pro Coil)\u003c\/li\u003e\n\u003cli\u003eAdjustability: single adjustable valving\u003c\/li\u003e\n\u003cli\u003eSpring: 9in high travel spring, 550 lb\/in rate\u003c\/li\u003e\n\u003cli\u003eSpring top: pigtail, large\u003c\/li\u003e\n\u003cli\u003eShock body: lightweight billet aluminum, fully threaded\u003c\/li\u003e\n\u003cli\u003eRide height adjustable\u003c\/li\u003e\n\u003cli\u003e100% dyno tested and serialized\u003c\/li\u003e\n\u003cli\u003eBolt-in installation\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003cli\u003eSold in pairs\u003c\/li\u003e\n\u003cli\u003ePart number: GS507-09550D\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1963 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1964 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1965 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1966 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1967 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1968 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1969 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1970 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1971 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1972 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1973 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1974 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1975 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1976 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1977 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1978 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1979 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1980 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1981 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1982 Chevrolet Corvette\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/9b6fbad111a2499d056e81f784a08e9e.PDF\"\u003eInstallation Instructions\u003c\/a\u003e\u003c\/p\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eIs this coil-over system adjustable?\u003c\/h5\u003e\u003cp\u003eYes.
