The front springs are wound from 5160 chrome silicon premium wire with a linear 530 lb\/in rate, and the rear springs are wound from 9254 chrome silicon premium wire with a linear 130 lb\/in rate. Ride height is engineered for a 2 inch drop with a standard small block, Pontiac 400, or aluminum head and intake big block Chevy as well as LS power, though lightened cars may require spring trimming. The front springs also suit full weight big block applications when a quarter inch nose down rake is desired. The kit works well for Auto-x, Pro-Touring, corner carving, and cruising, carries a durable black powder coat finish, and is made in the USA.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePosition: Front and rear\u003c\/li\u003e\n\u003cli\u003eLowering: 2 inch drop\u003c\/li\u003e\n\u003cli\u003eFront spring rate: 530 lb\/in linear (5160 chrome silicon)\u003c\/li\u003e\n\u003cli\u003eRear spring rate: 130 lb\/in linear (9254 chrome silicon)\u003c\/li\u003e\n\u003cli\u003eMaterial: Steel\u003c\/li\u003e\n\u003cli\u003eFinish: Black powder coat\u003c\/li\u003e\n\u003cli\u003eSold as: Kit (front and rear springs)\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003cli\u003ePart number: 4051\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1967 Buick Gran Sport\u003c\/li\u003e\n\u003cli\u003e1967 Buick Skylark\u003c\/li\u003e\n\u003cli\u003e1968 Buick Skylark\u003c\/li\u003e\n\u003cli\u003e1969 Buick Skylark\u003c\/li\u003e\n\u003cli\u003e1970 Buick Skylark\u003c\/li\u003e\n\u003cli\u003e1971 Buick Skylark\u003c\/li\u003e\n\u003cli\u003e1972 Buick Skylark\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\u003e1968 Chevrolet Chevelle\u003c\/li\u003e\n\u003cli\u003e1969 Chevrolet Chevelle\u003c\/li\u003e\n\u003cli\u003e1970 Chevrolet Chevelle\u003c\/li\u003e\n\u003cli\u003e1971 Chevrolet Chevelle\u003c\/li\u003e\n\u003cli\u003e1972 Chevrolet Chevelle\u003c\/li\u003e\n\u003cli\u003e1967 Chevrolet El Camino\u003c\/li\u003e\n\u003cli\u003e1968 Chevrolet El Camino\u003c\/li\u003e\n\u003cli\u003e1969 Chevrolet El Camino\u003c\/li\u003e\n\u003cli\u003e1970 Chevrolet El Camino\u003c\/li\u003e\n\u003cli\u003e1971 Chevrolet El Camino\u003c\/li\u003e\n\u003cli\u003e1972 Chevrolet El Camino\u003c\/li\u003e\n\u003cli\u003e1970 Chevrolet Monte Carlo\u003c\/li\u003e\n\u003cli\u003e1971 Chevrolet Monte Carlo\u003c\/li\u003e\n\u003cli\u003e1972 Chevrolet Monte Carlo\u003c\/li\u003e\n\u003cli\u003e1967 Oldsmobile 442\u003c\/li\u003e\n\u003cli\u003e1968 Oldsmobile 442\u003c\/li\u003e\n\u003cli\u003e1969 Oldsmobile 442\u003c\/li\u003e\n\u003cli\u003e1970 Oldsmobile 442\u003c\/li\u003e\n\u003cli\u003e1971 Oldsmobile 442\u003c\/li\u003e\n\u003cli\u003e1967 Oldsmobile Cutlass\u003c\/li\u003e\n\u003cli\u003e1968 Oldsmobile Cutlass\u003c\/li\u003e\n\u003cli\u003e1969 Oldsmobile Cutlass\u003c\/li\u003e\n\u003cli\u003e1970 Oldsmobile Cutlass\u003c\/li\u003e\n\u003cli\u003e1971 Oldsmobile Cutlass\u003c\/li\u003e\n\u003cli\u003e1972 Oldsmobile Cutlass\u003c\/li\u003e\n\u003cli\u003e1967 Oldsmobile F85\u003c\/li\u003e\n\u003cli\u003e1968 Oldsmobile F85\u003c\/li\u003e\n\u003cli\u003e1969 Oldsmobile F85\u003c\/li\u003e\n\u003cli\u003e1970 Oldsmobile F85\u003c\/li\u003e\n\u003cli\u003e1971 Oldsmobile F85\u003c\/li\u003e\n\u003cli\u003e1972 Oldsmobile F85\u003c\/li\u003e\n\u003cli\u003e1967 Pontiac GTO\u003c\/li\u003e\n\u003cli\u003e1968 Pontiac GTO\u003c\/li\u003e\n\u003cli\u003e1969 Pontiac GTO\u003c\/li\u003e\n\u003cli\u003e1970 Pontiac GTO\u003c\/li\u003e\n\u003cli\u003e1971 Pontiac GTO\u003c\/li\u003e\n\u003cli\u003e1972 Pontiac GTO\u003c\/li\u003e\n\u003cli\u003e1967 Pontiac Grand Prix\u003c\/li\u003e\n\u003cli\u003e1968 Pontiac Grand Prix\u003c\/li\u003e\n\u003cli\u003e1969 Pontiac Grand Prix\u003c\/li\u003e\n\u003cli\u003e1970 Pontiac Grand Prix\u003c\/li\u003e\n\u003cli\u003e1971 Pontiac Grand Prix\u003c\/li\u003e\n\u003cli\u003e1972 Pontiac Grand Prix\u003c\/li\u003e\n\u003cli\u003e1967 Pontiac Tempest\u003c\/li\u003e\n\u003cli\u003e1968 Pontiac Tempest\u003c\/li\u003e\n\u003cli\u003e1969 Pontiac Tempest\u003c\/li\u003e\n\u003cli\u003e1970 Pontiac Tempest\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat vehicles does this spring kit fit?\u003c\/h5\u003e\u003cp\u003eThe 4051 kit fits 1964 to 1972 GM A-Body models including the Chevrolet Chevelle, El Camino and Monte Carlo, Buick Skylark and Gran Sport, Oldsmobile Cutlass, 442 and F85, and Pontiac GTO, Grand Prix and Tempest.
