Alright, I'm planning on lifting the front of my 91 trooper another 1.5-2" by "cranking" the torsion bars, problem is I have no idea how to do this. I've done the search and there is a lot of talk about cranking them but I don't know what exactly you would be turning to achieve this? Is it the large nut beside the torsion bar under the driver door area? After doing this is it recommended to do a ball joint flip? This will be the only front suspension adjustment I'll be doing. I know this is a stupid question but I just don't know. My expertise is airplanes, not troopers...

yes. there is a bolt next to the torsion bar under the driver's side AND the passenger's side.

You have to turn them both exactly the same amount. You also need to make sure not to turn them so tight that the suspension loses all of it's droop, else it will feel like you are driving a jet ski.

I ran mine all the way to full droop and then let them back down 25 half-turns. That worked well and it drove fine.

Yes, I definately recommend a ball joint flip to go along with this. Also, use the search function and search for "T-bar Crank...

Good luck.

I went through a ton of different posts on the search looking for exactly how to do this. I actually didn't even know this was an option until I was browsing through some lift searches. I am aware that there is a nut for the passenger side as well, but thanks for being clarifying. So is it when you tighten the torsion bars that you gain lift? I was planning on jacking the front end up so the wheel was about 1.5 inches off the ground, and cranking the torsion bar until the wheel was touching, repeat on the other side. Drive it around for a bit then measuring the make sure they were both the same. Does this sound good? What's the max you can do this? With out having a horrible ride?

Thanks for all the advise!

Can't do it that way. When you jack up the truck, the suspension will droop until it is maxed out. Just measure up to the fender, crank some, measure again until you get it where you want it. Turn the bolt heads clockwise to gain lift. Each turn will equal roughly 1/4" of lift; but you will have to do a bit of fine tuning. The bolt heads are 27mm, btw.

[edit]If you do 2" of lift, you may benefit from flipping the ball joints. Shouldn't need a spacer with that much, though.

Thant makes sense. Thanks for the help.

Of course, I should say that this isn't the "right" way to do a lift, and it can affect your ride and give you undesired results, so try it out before you spend a lot on tires and such. That way, you can always put it back. The most important thing is to keep track of how many turns you go with the bolt so you CAN put it back if needed.

The ball joint flip corrects the suspension geometry from turning up the torsion bars. If you find that your suspension is bottoming out when you drive, check your bump stops to see if you need to trim them up a bit.

Also, make sure you are not stressing the brake lines with your new height.

Just so u know, when u turn up the torsion bars, you will mess up the alignment. The wheels will tip in on the top like this /---\ looking from the front of the vehicle. I believe this is called positive Camber. it may also create a negative Toe and make the wheels pull out to each side \---/ looking from the top down...

Ya, I was planning on taking it in to get an alignement after I adjusted and tweaked the torsion bars, goal is to get about 1.5" of lift. Thanks for all your help. <img src="/forums/images/graemlins/cheers.gif" alt="" />

Make sure you get an alignment shop that can adjust your camber, not just toe. The camber will be out because of the suspension lift. It CAN be adjusted by a good shop. Incompetent shops will tell you the camber can't be adjusted because you "took it out of factory specs."

alright, good to know. I didn't think they would be able to adjust the camber after. Thanks.

This site is great for advise. I hope to be able to offer my own soon too.
