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 double adjustable compression and rebound 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: double adjustable (independent compression and rebound)\u003c\/li\u003e\n\u003cli\u003eShock material: lightweight billet aluminum\u003c\/li\u003e\n\u003cli\u003eSpring: 10 in, 500 lb rate\u003c\/li\u003e\n\u003cli\u003eSpring end: tapered pigtail\u003c\/li\u003e\n\u003cli\u003eCompressed length: 10.13 in\u003c\/li\u003e\n\u003cli\u003eExtended length: 17 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: GD501-10500A\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1965 Buick Gran Sport\u003c\/li\u003e\n\u003cli\u003e1966 Buick Gran Sport\u003c\/li\u003e\n\u003cli\u003e1967 Buick Gran Sport\u003c\/li\u003e\n\u003cli\u003e1964 Buick Skylark\u003c\/li\u003e\n\u003cli\u003e1965 Buick Skylark\u003c\/li\u003e\n\u003cli\u003e1966 Buick Skylark\u003c\/li\u003e\n\u003cli\u003e1967 Buick Skylark\u003c\/li\u003e\n\u003cli\u003e1964 Buick Special\u003c\/li\u003e\n\u003cli\u003e1965 Buick Special\u003c\/li\u003e\n\u003cli\u003e1966 Buick Special\u003c\/li\u003e\n\u003cli\u003e1967 Buick Special\u003c\/li\u003e\n\u003cli\u003e1956 Chevrolet Bel Air\u003c\/li\u003e\n\u003cli\u003e1957 Chevrolet Bel Air\u003c\/li\u003e\n\u003cli\u003e1964 Chevrolet Chevelle\u003c\/li\u003e\n\u003cli\u003e1965 Chevrolet Chevelle\u003c\/li\u003e\n\u003cli\u003e1966 Chevrolet Chevelle\u003c\/li\u003e\n\u003cli\u003e1967 Chevrolet Chevelle\u003c\/li\u003e\n\u003cli\u003e1964 Chevrolet El Camino\u003c\/li\u003e\n\u003cli\u003e1965 Chevrolet El Camino\u003c\/li\u003e\n\u003cli\u003e1966 Chevrolet El Camino\u003c\/li\u003e\n\u003cli\u003e1967 Chevrolet El Camino\u003c\/li\u003e\n\u003cli\u003e1964 Chevrolet Malibu\u003c\/li\u003e\n\u003cli\u003e1965 Chevrolet Malibu\u003c\/li\u003e\n\u003cli\u003e1966 Chevrolet Malibu\u003c\/li\u003e\n\u003cli\u003e1967 Chevrolet Malibu\u003c\/li\u003e\n\u003cli\u003e1955 Chevrolet Nomad\u003c\/li\u003e\n\u003cli\u003e1956 Chevrolet Nomad\u003c\/li\u003e\n\u003cli\u003e1957 Chevrolet Nomad\u003c\/li\u003e\n\u003cli\u003e1955 Chevrolet Truck\u003c\/li\u003e\n\u003cli\u003e1956 Chevrolet Truck\u003c\/li\u003e\n\u003cli\u003e1957 Chevrolet Truck\u003c\/li\u003e\n\u003cli\u003e1955 Chevrolet Two-Ten Series\u003c\/li\u003e\n\u003cli\u003e1956 Chevrolet Two-Ten Series\u003c\/li\u003e\n\u003cli\u003e1957 Chevrolet Two-Ten Series\u003c\/li\u003e\n\u003cli\u003e1964 Oldsmobile 442\u003c\/li\u003e\n\u003cli\u003e1965 Oldsmobile 442\u003c\/li\u003e\n\u003cli\u003e1966 Oldsmobile 442\u003c\/li\u003e\n\u003cli\u003e1967 Oldsmobile 442\u003c\/li\u003e\n\u003cli\u003e1964 Oldsmobile Cutlass\u003c\/li\u003e\n\u003cli\u003e1965 Oldsmobile Cutlass\u003c\/li\u003e\n\u003cli\u003e1966 Oldsmobile Cutlass\u003c\/li\u003e\n\u003cli\u003e1967 Oldsmobile Cutlass\u003c\/li\u003e\n\u003cli\u003e1964 Oldsmobile Vista Cruiser\u003c\/li\u003e\n\u003cli\u003e1965 Oldsmobile Vista Cruiser\u003c\/li\u003e\n\u003cli\u003e1966 Oldsmobile Vista Cruiser\u003c\/li\u003e\n\u003cli\u003e1967 Oldsmobile Vista Cruiser\u003c\/li\u003e\n\u003cli\u003e1964 Pontiac GTO\u003c\/li\u003e\n\u003cli\u003e1965 Pontiac GTO\u003c\/li\u003e\n\u003cli\u003e1966 Pontiac GTO\u003c\/li\u003e\n\u003cli\u003e1967 Pontiac GTO\u003c\/li\u003e\n\u003cli\u003e1964 Pontiac LeMans\u003c\/li\u003e\n\u003cli\u003e1965 Pontiac LeMans\u003c\/li\u003e\n\u003cli\u003e1966 Pontiac LeMans\u003c\/li\u003e\n\u003cli\u003e1967 Pontiac LeMans\u003c\/li\u003e\n\u003cli\u003e1964 Pontiac Tempest\u003c\/li\u003e\n\u003cli\u003e1965 Pontiac Tempest\u003c\/li\u003e\n\u003cli\u003e1966 Pontiac Tempest\u003c\/li\u003e\n\u003cli\u003e1967 Pontiac Tempest\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 1955-1967 GM A-body and full size 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.
