Ive seen some other blazers around town and they look like they are sitting alittle bit higher than mine, and i understand if i crank up the torsion bar it should be me like another inch or so, i jus want a few more inches, nothing huge, if i were to crank it up, would it do any damage to the suspension or anything? and also how do you "crank" the torsion bar??

There will be two bolts on the torsion bar, one on each size. To lift it simply drive the bolts in, to lower you loosen the bolts. No you aren't doing any damage to the suspension thats what the torsion bar is there for. Depending on how cranked up yours are will depends on the amount of lift you will get.

from your other post about the squealing belt, it appears you have a 98. however, i dont know if its 4wd or 2wd (put your truck info in your signature ).

assuming its 4wd,
if you look at the lower control arms on your truck, there will be a large bar (outlined in red, pic below) about 4ft long running the length of your truck (one for each side)

if you follow the bars as far back as they go, you will see a crossmember that runs perpindicular to the frame where the bars attach. there are two bolts sticking out of the crossmember. turning the bolts clockwise will lift the truck and turning them counter clockwise will lower the truck.

as far as suspension wear, yes, cranking the bars affects the front suspension. cranking the bars effectively lowers the LCA's away from the frame, the CV shaft angles will increase and can put more stress on the ball joints...  as to how much damage will actually be done depends vastly on the way you drive it.

there are quite a few threads that go into more detail so searching will answer wuite a few questions too.






damn, brett beat me to it while i was looking for pics.

I would like to clarify the statement that Brett made.  You will shorten the life of suspension and drivetrain components in the front end with too much lift.  You can safely lift it around 1.5" before you will potentially damage the ball joints and front halfshafts.  Pushing it to 1.75" may work, but trying to get to 2" is where many, many people have had major issues, stock or aftermarket keys.

And that isn't mentioning the change in ride quality that will happen.

Just do it!  If you change your mind you can just let the bolts back out.  But I went up 1.25'' or so and after about 70 miles blew out my passengers side CV half shaft.  Could be from the 100k miles already on em, but who knows!  Also speed bumps are an absolute PITA.  Once I replace my shocks I'm sure the ride will be bit better.  The extra height is real nice, and the level appearance is great too!  That's why I say just go ahead and do it now

quick question off of this one, how many times do you have to turn the bolts to get an inch or so of lift? and dont you need to get an alignment after?

1 full turn is supposed to yield .25'' of lift. 

Depends on a few other factors though, a few people have gotten an inch out of 3 turns..Me with my brush guard up front took 5 turns to get an inch.

And definitely get an alignment afterwards.

Stupid question, but do you have to have the vehicle off the ground to adjust the t-bars?

not a stupid question. and you only have to have the front suspension off the ground, for the side you were doing, or just both at the same time.

Mine looks like the back is actually lower than the front. The new shackles should take care of that though.
