Biltein 5100's on a non TRD

I’ve got a 95.5 Taco 4x4 non TRD and am thinking about getting the 5100's. I recently put an add a leaf in the back to alleviate the rear end sag and axle wrap, but now the rear sits higher than the front. Truck has Rancho shocks on it now and rides rough as hell, but the back is a little bit better now that there is a little arch back in the springs. I want to get the 5100 so that I can level the front out. I have no lift and am running 31" tires. What kind of ride can I expect from the 5100's with this set up? Thanks in advance
