Ok so in my future i will be buying a 3 or 4.5 lift but my stock rear leaf springs are sagging. So the new lift will even everything out but it will probably sag again because i have a 12 inch sub in the back and a custom tool box that take up basically the whole cargo area so that, im assuming that the weight of that over time will make the rear sag again so i can go with like 1 inch blocks in the back but what would i use for my new u bolts? Who has them long enough use for the lift and the blocks?

 

To answer your question the blocks will come with them... Or they can be had at napa...

However your toolbox and sub aint gonna make a difference... Maybe buy a steel front bumper... Thatll level u back out...
