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

This product is a game-changer for anyone looking to upgrade their suspension. As my tests showed, the Hyperco CS100 Length Helper Spring provided a noticeable improvement in handling and overall performance. The easy installation and durability were also huge pluses. However, the price point may deter some buyers from taking the plunge. Overall, I highly recommend this product for those serious about optimizing their automotive suspension.

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!

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.
