Review on 🔵 Hyperco CS100 Blue 2.50" I.D. 4" Free Length Steel Helper Spring: Enhanced Performance and Durability by Aaron Cruz

Serves its purpose well. I bought these to complete my front coilover kit so that the mainspring doesn't have any free play when my car is jacked up or when the wheel goes down past the extension of the mainspring. All is well! Don't forget to get a spring spacer when you add them!
