So just stopped by local off-road shop, Truckin Up, and let me say he was very helpful. (Jrobson can relate). After hearing about j's truck he gave me alot of tips.
First my truck is 2010 and has vsc. He said dont go over 2.25" b/c bad on cv angles even with diff drop. He said no 3" lift either cause bad cv damage. But if you decide to go 6" it voids your warranty. He also said I would have to get 18" wheels w/ lift for proper clearance b/c of the newer suspension geometry. So after all is said and done he convinced me to go with 2.25" readylift. This way with diff drop, no cv damage and still under warranty. Sorry for the long post but just wanted to help out anybody thinking of lifting a 2010 taco. Also Jrobson, your truck is gonna look sweet! According to Truckin Up, he almost blew a cv joint with the Toytec ultimate lift, ouch. Sorry jrobson for using your info, but I thought it was helpful
