Search for 2009. Most kits are shown as fitting up through 2010 because the 2500 series trucks changed suspension designs in 2011, however the 2500 series SUVs stayed the same until their last model year of 2013.
I personally like the Cognito NTBD kit. It has the shortest track width increase without sacrificing turning radius, and it comes with the PISK kit included, that's a $200+ upgrade to add to other kits.
BDS was a close 2nd for me but they wouldn't tell me how much the turning radius would be affected with their narrow knuckle option, only that it would get larger.
