stance help

hey everyone. i was looking for some advice and opinions on an idea i have. i want to lower my 99 gmc jimmy a couple of inches. i found a block kit for the leaf springs in the back. and i believe there is a way to unload the tortion bars. and eventually i need new shocks. is this safe to do? and how will the ride be? thanks everyone, -slopez

so the Jimmy is a 4x4?

well, about that. it is a 4x4, but it dosnt kick into 4wheel right now. i noticed some hoses hanging under the truck one day, and i was told they were vacume lines for the transfer case. they melted. but ya, its 4x4. i dont use it much in the winter, i have my pick up for that
