Do I need my bump stops?.... my spacers won't fit over them without some fab.... or do I just have to fab it up lol

 

are you talking about the bump stop tower up top? yes, you need that.. not sure why the spacers wouldn't fit over them, they should be designed to do so

 

Yeah were grinding down some un necessary metal we got one on already thanks man

 

If they are the stock bump stops. Just unscrew them install spacers and swrew them back on.

 

Just finished installing my 4.5 inch lift.. when driving it makes a noticeable humming noise once I let off the gas it makes a nasty grinding sound... is this normal

 

does it vibrate?

 

Yeah a little bit. Could it be my pinion angle?

 

it could. did your leafs come with a pinion angle shim?

 

No its an add a leaf kit... I added drop shackles and spring spacers to make my 3 inch kit a 4.5

 

you need a pinion angle shim and more than likely a sye. a 1" tc drop should hold u up for now.

Ok ill check em out this week. How do I get more flex capability?....

 

front or rear?

 

more so the front but both in the end.

 

longer brake lines, actual 4.5" shocks (although my buddy had better luck with 6" shocks on 4.5" lift), longer lower control arms.
and not specifically for flex, but just to keep things from over-stressing during flexing, get a drop pitman arm and a track bar drop bracket.
