what kind of truck do you have -- you can lower the front as well..depends on what you have upfront..
a lot of people remove the rear blocks. I think it would look kinda goofy if its stock and sitting low..not much of a prerunner look just not level and small tires..but i dunno what you got..so it might be nice
ive thought about something similar. but going to maybe a 1" block or something instead my bars are near cranked all the way and the truck barely sits level. i can only imagine in another year or so after it sags ill have the same stock looking rake
if you were to do it, id say flip the shackle hangers, and keep the blocks, you get 2 inches lower in the back and gain some travel, if you have the right shocks i mean. i havent done it to my truck yet but im thinking about doing in the next couple months or so.
