Icon Coilovers - How many miles till springs wear out?

I have Icon extended travel coilovers on my 2006 DCSB and was wondering how many miles can be expected from them before needing to replace coil springs? I have about 180k miles on them now, and they seem a bit softer than when new.

I have a plate bumper and full skids.

 

Rebuild them. Good rule of thumb is 2 years or 40k miles depending on how you use them.

 

I've had them rebuilt (seals, oil, etc.) what I am asking about is the coil springs.

 

Ahh gotcha. I'd say you are do for new coils at 180k.

 

That is what I am thinking.

Spring install by Icon during rebuild?

 

I would just send them to downsouth motorsports, they do excellent work and have rebuilt my kings before.
