Springs drop at full flex

At full flex my bumpstops connect but I notice that my spring has separated from the body. Is this something I should fix?

4" rough country lift

Looks like you need longer bumpstops to match your taller springs.

I think I see bumpstop extensions bolted to the spring pad...which is where they should be for the front....

as for the spring unseating, this is normally caused by springs that have too short an unloaded length, or shocks that are too long.

the amount of unseating there isn't too bad, as long as you have the retaining clamps installed to hold the spring in place. if you want, you can add limiting straps to prevent the shocks from busting under droop.

Just keep in mind an unseated spring is useless for traction & weight distribution. I prefer the spring to be slightly loose but still contacting the spring isolator, or maybe 3/4"-1" unseated at the most.

I have a 2" puck on the axle for the bumpstop. On the compressed side the bumpstops meet so I don't think that is the issue.

UnlimitedLJ04. I was thinking exactly all of your points today. No traction.
I have the spring retainers on the axle if that is where you meant.
I was also thinking about the JKS ACOS (I'm about to add a winch, so concerned about the rake).
Then I thought, hell why not just get some longer springs?? Then i can be finally rid of this rough rough country. Thoughts?

That's not even close to fully compressed. The yellow jounce bumper will completely compress into the cup. So the bumpstop could be an issue for a different reason...not enough, causing shocks to bottom out. You need to check that with the springs removed. Nothing to do with the spring unseating under droop though.

Bingo. Adding a spacer doesn't solve an increased weight problem, it just reduces the space the spring has to compress into and makes things look more level, while the Jeep is sitting still. Swapping to springs of the proper rate and length will compensate for increased weight due to armor/winch/cargo.

oh ok. thanks, I didn't realize the yellow bumper can collapse.

How do I determine rate and length, and manufacturer?

Call manufacturer of springs and ask them what the spring rate and unloaded length is. Spring rate should be in lbs/in. (Pounds per inch) Unloaded length should be in inches.

Figure out what you have now. Determine the ride height you want. Do the math to figure out what spring rate you'll need to support the added weight. Buy a spring that fits your needs...from whichever manufacturer makes it, regardless of the advertised "lift".
