A fully threaded shock body sets the ride height for the desired stance and helps fine tune weight balance, while the lightweight billet aluminum coil-over shocks offer single adjustable valving. The specially designed high travel springs use fewer coils and a smaller wire diameter for added travel, reduced unsprung weight and faster response. Each system installs with basic hand tools, is 100 percent dyno tested and serialized, and can be serviced and rebuilt by QA1 authorized service centers. Made in the USA and sold in pairs.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: GM front Pro Coil coil-over system\u003c\/li\u003e\n\u003cli\u003eAdjustment: single adjustable\u003c\/li\u003e\n\u003cli\u003eShock material: lightweight billet aluminum\u003c\/li\u003e\n\u003cli\u003eSpring: 9 in, 550 lb rate\u003c\/li\u003e\n\u003cli\u003eCompressed length: 9.63 in\u003c\/li\u003e\n\u003cli\u003eExtended length: 14.5 in\u003c\/li\u003e\n\u003cli\u003eMounting: stock mount, bolt-in\u003c\/li\u003e\n\u003cli\u003eSold in pairs with mounting hardware\u003c\/li\u003e\n\u003cli\u003eMade in the USA\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\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat vehicles does this QA1 Pro Coil system fit?\u003c\/h5\u003e\u003cp\u003eIt is designed for 1963-1982 Corvette applications listed in the vehicle applications section of this listing.\u003c\/p\u003e\u003ch5\u003eIs this coil-over system adjustable?\u003c\/h5\u003e\u003cp\u003eYes.
