@Rock Krawler Suspension , can you post the extended/compressed lengths of your springs along with the spring rates? I saw partial spring rate data in another thread, but couldn't find anything on lengths (net even on your website). It would be nice to have all of the info in one place. Providing the overall spring length when the tender portion is collapsed as well as the force to get there would be great.

I'll work on getting that added to the website.

At the 1:31 mark he states that the coil is a front then he states that the same coil is a rear after talking about it. Iā€™m confused.

That's a rear coil, Jeremy still gets nervous in front of a camera, sorry about that.

Bringing this topic back to life... I am looking at getting your 2.5 triple rate springs for a JL. Is the 2.5 lift based off a rubicon or a sport? I.e. will my sport actually be lifted higher then 2.5 since it was originally measured for a rubicon?

All of our 4 door JL lifts are based off of Rubicon height so, yes, your sport will gain 2.5" plus the height difference of a rubi vs a sport, which is roughly 3/4".

At what point do you stop designating the number of rates and just call it a progressive coil? Hex-rate? Oct-Rate?
Well, that's not how it works. A dual/triple/quad will have a defined rate change position and between those change positions, they are a single rate whereas a progressive simply gets more rate as it is compressed. Being able to define the transition points allows you to define how the vehicle performs between known points in the spring.
