HYPCS600 Hyperco Hypercoils SPECIALTY SPRINGS(6"F.L.X2.50"I.D.)

Serves its purpose well. I bought these to complete my rear coilover assemblies so that the main spring would not have free play whenever my car was lifted or if the wheel dropped beyond the main spring's extension. All is good! Don't forget to get a spring spacer if you're adding these!

Exactly what i needed at the right price. Have had zero issues out of them and they haven't rusted out.

Fit is good on koni yellow shock with ground control sleeve and ground control adaptor. No more loose springs when the car is lifted.
