well the final verdict is in......I didn't lose anything.......the rear netted me absolutely nothing, the measurements are literally identical (+/- 1/16")......the middle of the jeep (center of rock rails) are is 3/8" higher and the front bumper is 3/4" higher.
The funny thing is just looking by eye, it doesn't look any different but the tape measure doesn't lie. Never noticed if I may have had a slight rake before, as it looked pretty level. And even now post lift it still looks just as level as it was.
Overall I am happy I went ahead and did the lift without leaving the spacers in. One thing I did notice, is I can really feel the difference in the rear with the axle side rear trackbar bracket installed. It centered the rear axle nicely, and just seems to have tightened things up back there....hard to explain.
Really looking forward to hitting the trails with it over the weekend!!!
