Leveling the AT4

[Big_Kahuna]

Anyone done it? Let’s see some pics, let us know what kit you use , did you run in to any problems?

Get a kit with new UCAs. 

 

Stock AT4 arms are the same arms as a non AT4, and in AT4 configuration are at their limit.  GM has denied many a warranty on TB/AT4 trucks with a level for failed upper ball joints.  They rip out pretty good too.  Usually take the CV with it.

newdude is 100% correct! 

 

The UCA's are close to max'd out on the TB/AT4's and many people who try to level the truck with 1-1.5" puck lifts have experienced UCA failures that generally result in CV failures as well.  If you're going to level your TB/AT4, make sure you get upgraded UCA's as well, its not worth taking the chance considering how many failures are occurring in that manner.

can anyone confirm which ones done squeak as far as UCA goes ? Is it the Poly Urethane that makes them sqeek ?
