EXT Z55 Autoride lift

[SlickA70]

I imagine this has been asked 100x but I hear some conflicting info.

I have a 2007 Escalade EXT AWD/Z55, I want to buy the RC 3.5" lift for an 07 Avalanche 4WD.

I will have to:
- Extend front ride control sensor wires or notch the spacers to make the plug fit
- Extend level control rods all around, either with the threaded rod or with a coupler to maintain level/ride control
- The kit comes with rear shock extneders so that should keep the shocks where their meant to be.

Few questions:
- Will the RC upper control arms work for the EXT if they are meant for an Avalanche?
- The kit will lower the transfer case, will this effect the AWD? If so I could need a new driveshaft?

I want to get this all right before I do anything, don't want do spend for a Skyjacker kit either (wife lol).

I also have 100% new Z55 suspension at all 4 corners (shocks, springs, bump stops) and would hate to mess something up.

I think your first concern is that AWD. I looked at the same kit for the sierra, it specifically says does not fit AWD

I've asked a few people with lifted AWD and they said 3" or less it should be fine but may need to be replaced if old, 3"+ swap for a different style CV driveshaft instead.

rc sells a driveshaft that will make the kit work
