On the springs, talk to outlaw about what rates they're using. They've got more time on that kit than anyone.
H&m's rates are likely set up around having a full engine cage (more weight).
Yes they told me to call them on monday, because the person who knows about lts kit wasnt there.
h&m told me to open all the way long tube and short tube comp and go tested.
Yes, offcourse their truck is heavier than stock because of the gussets, cages and fiberglass hood.
They will be sending me a 700 spring rate.
You note how firm is that spring when you see the pre load ring all the way on the top and truck still nose high.
