Great springs, and give about 1" of lift over the default 600# springs (assuming stock weight),
With the weight of a stubby bumper, winch, AL skids and steel sliders, I ended up having about a half an inch of lift ontop of the circlip reference chart.
E.G. clip7 (1.4") + .5" lift = ~2inch
I do however second guess whether I should have compensated for the driver's side lean using a spacer instead of preload as even though my driver's side sits statically level with the passenger side, there is a nominal difference in dynamic response and handling between the sides that is fairly noticable on uneven terrain, braking and throttle.
