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

I have lowered and beefed up my car's suspension to the point where, at full sag, the springs were several inches shorter than the distance between the spring lugs . I used a HyperCo assist spring along with an Eibach spring clutch to keep my spool over the suspension throughout the range of motion. The Helper springs were high quality with durable powder coating and constant spring rate on all four springs I installed.
