Spring Rate Table

[don2510]

Are the spring rates that are installed in the varies Jeep models listed anywhere or are the spring rates listed by part number and pounds per inch shown anywhere? I am installing a winch and bumper on my 2021 2 door rubicon and would like to change the front springs instead of using a spacer.

Spring rates gathered over time. Not a complete list, and some of this may or may not have changed as years progressed. Data on Clayton and Synergy are listed on their pages so they are accurate. JKS data is from a recent enquiry I made with them as I was shopping for a 2.5" coil spring (fall-2023)

Good info. Should be added as a sticky / pinned thread.
