I have had 33 inch duratracs, old man emu shocks, and the teraflex leveling kit (2in front, 1in back). I already did the grade 8 bolt replacement on the control arms.
My tires are inflated at 35 psi, I did the chalk test and frankly it looks the same to me at 30 psi and 35 psi...except I get better gas mileage at 35, although my ride feels a bit rough. I WILL LOWER MY PSI TO 30, EAT UP THE MILEAGE DIFFERENCES, to see whether or not that solves the roughness issue. I have kept psi at 35 for 1 year so I forget how 30 psi feels.
I have money to spend. Fox shocks look enticing...but what else should I do? The simple teraflex leveling kit does not warrant adjustable trackbar/control arms I feel.
