I've got an 08 SCrew still stock. I wanted to add a leveling kit and AAL in the back. My end goal is to have the truck as level as possible. Any help on the size leveling kit I need would be greatly appreciated

 

Probably a 2 in spacer. Measure from the ground to the top of your fender well in the front and rear and subtract the two. I know on my 04 it took a 2.5 in spacer to get mine perfectly level without the rear blocks. I can't remember if the 08 takes the same or .5 in shorter. Someone with an 08 please speak up and help a brother out.

 

I have an 08 SCrew 4x4 and a 2.5 in spacer would make my truck sit perfectly level. It's going to be hard to get close to level with an AAL though as they add about 1-2 inches. If you can find a AAL that only adds 1 inch you would get close with a 3 inch spacer up front but it is generally considered a bad idea to go more than 2.5 inches up front due to the extreem angles it causes. You didn't mention if you had a 4x4 or 4x2, this is all for a 4x4, it's slightly different for a 4x2.

 

Mines just a 4x2. I found a guy last night with the same truck last night. He went with a 3" on the front and 1.5" aal on the back. The truck sits exactly how I want it to. He claims he's had his installed for 60,000 miles with no problems. Thanks for the help though

 

Go with that then...

 

This is exactly what I did. It sits perfectly level and 1" taller than a stock 4x4. Mine is 2x4

 

Could you post link to the aal you used.
