Confirming Steps to Replacing RAS with Coils

[Pekoe1111]

The rear air suspension gave out on my 2008 Limited so I’m having my mechanic replace with coils. Can anyone confirm the approach? Am I missing anything?

I bought Icon rear 2” lift coils because I have 2” coil spacers up front. I also bought the MetalTech kit with coil top isolators and coil bottom seat bracket. So the plan is to replace the air bags with coils and pull RAS 10A fuse and RAS relay.

I also have XREAS that seems to be working fine, so I’ll ask my mechanic to be careful of those lines. When it craps out, I’ll be looking at Bilsteins or Eibachs.

Is that it?

Thanks

Not for sure but I think you may need bump stops to keep the suspension from bottoming out because I don't think the air suspension has bump stops, hopefully someone can confirm if this is correct.

Sounds like it’s a pain to get the retaining clips off the airbags. Any tips?

Sorry to revive a dead thread but how did your truck sit after you did this? I'm about to do mine but I'm not sure which size lift coils to get as I've heard the kit itself gives 0.5" of lift and my front end has 2.5" spacers up front.
