1963-1977 7 Leaf Steel Heavy Duty Rear Spring - 2.25 Inches Wide

Our Corvette OE Style Heavy Duty 7 Leaf Steel Rear Springs are a direct replacement for your 1963-1977 Corvette's original equipment. 7 Leaf Heavy Duty Leaf Springs were standard equipment in all Big Block equipped Corvettes and Small Block cars with F41 or FE7 Gymkhana Suspension options. Manufactured to exceed OEM specifications, these springs offer exceptional ride and handling characteristics.

  • Heavy Duty 7 Leaf
  • 307 lbs per inch rating
  • 2 1/4" wide
NOTE: 1977-1979 Corvettes using this 2.25" wide spring require spacer shims to fill the 2.5" width between the mounting bolts that secure the spring to the differential cover. In addition, many 1977-1979 Corvettes have been updated with heavy duty differential covers that will not accept a 2.5" wide spring.
