I'm going with the motofab level but I'm torn. I'm thinking either the 2.0 front or the 2.5 front with the 1.0 rear. How level is your 2.5? I was afraid of mine being too nose high at that height.
It's pretty level, with about a quarter to half inch lower in the front.
Measuring before from ground to middle of fenders, 39" in back, 36.25" in front.
Measuring after; 40.75 in the rear, 40.25" in the front.
Stock tires were 31" mounted, new tires are 34.75" mounted.
I've read so many different pre-level fender heights and it varies truck to truck, model to model. I went with 2.5 because I had a lot of rake factory. 2.5" worked well for me.
