2008-2011 ABS/ Advance Trac Question....

[RK Racing]

I have a 2011 2wd with coils.
I was talking to Fab tech today about their 5.5" 2wd lift for up to a 2008.
I asked why do they not list it up to a 2011?
They stated they tried to put it on a 2009 and up and had ABS/ Advance Trac problems/codes show up so they do not offer it for a 2009 to a 2011 just for that reason but not a fitment issue.

Any advice?

I can't think of anything that changed in that time frame. It makes me wonder how hard they tried to diagnose those issues and if they screwed something up.

According to Fab tech the 2009 and up have a Avance Trac sensor issue.
According to Doetsch the 09 and up does have that problem but the dealer can reset it.

If you have dealt with this issue PLEASE chime in, Thank You!

speculation,, perhaps the raised center of gravity, thus changed pitch and roll are something the stock system can't handle???
