If they do end up making them for the newer trucks, I would consider only 4.56's. Reason I say that is i'm pretty sure the newer trucks have the 6 speed tranny not requiring an ultra low gear. With the older 4 speeds a tad lower gear helps.

IMO 4.88s is too much for just 37s and even my 38s now, 4.56s would work well but this is also on a 09

Thanks for all your input. I guess I'll keep my eye out for a release of the 2011+ gearing.
