Progressive Rate Coil Springs are a great way to increase ride height and off road ability while improving ride quality. Unlike Single Rate coil springs, Progressive Rate Coil Springs are designed to have multiple rates built in. This means the load in your Wrangler JK will not affect their performance. Single Rate springs always respond at the same rate. This can cause a harsh bumpy ride, or unnecessary sag. Rubicon Expresss Progressive Rate Coil Springs can handle any terrain that comes your way no matter the load in your Jeep.
