Ok next weekend im gonna install my spindles and in the rear imma have short AAL's and a 3 inch block...i already got the longer ubolt and i was wondering if this will be enough to get the *** end level to the front? Will i have to throw in the chevy lowering shackle?

 

The rear end is already higher then the front unless you cranked the t-bars up to level out with the back already....If you have done that, then you should be even when you put the front and rear lift on then!

I have the ProComp 3.5" Lift with 2" AALs and 4" Blocks along with 3" BodyLift and .5" T-Bar Crank...So I have 7" of total lift all around and is leveled out

 

I'd leave the shackle off. Sounds like you'll have enough already and if you leave it off you won't have to be concerned with possible pinion angle problems and drivetrain vibration.

Are you putting traction bars on now? With 4.88's and 35's you really need them.

 

I'm assuming you are referring to me..I have thought about that as well...I haven't had any problems whatsoever with it..My truck sees the master tech at Ford(A guy I have known for years and a good buddy of mine), don't get charged or written up for anything that I need done, does a check up on everything everytime I go in and he says all is good to go..

How much does it help though John, and actually what does it help/do...Thanks in advance man!
