The 4x4 ratio is 3.62:1, the 2wd ratio is 3.64:1. It will run no bother, I am running the same set up in my Escos, if you want to ask someone else talk to Marco off here, as he knows all about this, but it will be fine! Plus then you can fit 108mm rear 2wd shafts instead of the 100mm 4x4 ones, the stubs are the same size so all slots in, just get meatier cv's and shafts, win win situation
