coil overs

i was reading that a member got some Monroe Sensa-trac Load Leveler shocks with coil overs. that it raised his payload capacity and when there was nothing in the blazer that it gave him an inch of lift. so if i got 4 all the way around would it give me a bit on height and some stiff shocks at the same time? would that work?

thanks

They are only made for the rear shocks.  The ride was worse with nothing in the bad.
