I have the 3" TeraFlex system and have not had any issues.

 

3" FT Economy with adjustable track bars. Once I got the steering wheel centered almost no problems. It still kicks in when on a turn with an incline. Not very many hills where I live so I don't stress it much. I am finally getting my new tires tomorrow so I will have an alignment done at the same time and see if it gets it perfect.

 

no issues on my 3" tera flex once i added adjustable lower front control arms and front track bar.
before that ....
it was like a giant SPERM on meth and the damned esp lit up like my Mom when she caught me .... well errmmm ...

 

I have the FT 3" Ultimate, and really like it. But the ESP started acting up right away. It was a professional install, and they work well with my dealer. So they got me in today for a flash, the steering wheel was centered. I went for a test ride with the tech and everything was fine. Drove to the office with no issues, then on the way home it started again. It kicked in at 25mph on an onramp. The installer and the dealer are working on a solution. Keep your fingers crossed.

 

i have procomp 4" and no problems what so ever....

 

2.5" TF HD BB, 33's, no problems, been installed one week now.

 

All lifts should effect ESP the same.
