1963-1982 Hyperco Composite Rear Spring - 200 lb/in

Our performance tuned 1963-1982 Corvette Hyperco Composite Rear Leaf Springs allow you to select the suspension performance level and ride quality you desire. Hyperco's HPS (High Performance Street) series provides improved cornering ability, road feel and initial response while maintaining a quiet and comfortable ride.

This EZ Ride spring features the same 200lb/in rate as the stock 9 leaf spring as well as the OE 1981-1982 composite spring. The reason for the low spring rate is because of the springs high arch. Other composite spring need to have a higher spring rate because the arch is very low. This spring is an excellent choice for everyday cruiser.

  • Fit All 1963-1982
  • 200 lb/in Rate 
  • Reduce Unsprung Weight
  • Cycle Tested to OE Standards
  • Configured to "Optimize" Severe Stress Points
  • Made in the USA
