I also went with 2721 springs. See my quoted post below. I have about 0.75" of rake on setting #5.
Depending on how much rake front to back you have currently, may need more lift on the front to get it leveled.
Thank you for the info. Looks like u have a front bumper so that brings the expected value from 2.6" to 2.25". I am mostly stock so expect to be closer to stated. I was expecting the 2721 to be higher than 1.5" (Slee mentions 2" with 2721) but I guess if I go to 3rd perch I should be at ~1.75", so not too far from the rear. Since I am also upgrading the UCA I was planning on more of a 2" lift. How would one increase the rear to 2.0" within increasing spring rate, I assume some sort of a spacer but I typically don't like that route....
