Just had the torsion bars adjusted and he told me all he could get out of them was 1 1/2". That's all I wanted but from what I've read here shouldn't there be at least 2" of adjustment, or does it vary from truck to truck? Oh by the way I love the new look and it didn't hurt the ride one bit. :)

From what I've read and heard they can vary slightly from truck to truck! Some guys say that one side was cranked more than the other! Just depends! But 1 1/2 to 2 is about average!

It does vary from truck to truck. Look under your truck and see if you can see threads between the bolt head and the nut.

definately varies from truck to truck as well as side to side. Me and my buddy just cranked the bars on his '97 dakota. Went up quite a bit to start (impatient). got a good 3" on one side but only about an inch and a half on the other.

it does vary truck to truck. i only got 1.5" out of my truck as well, i added green keys and im up to 2.5" and could go alot higher than that if needed.

If you crank up the torsion bars, you really need to get shock extenders or you will break shocks. Other alternative is get the longer shocks offered by bilstein, made for cranked bars. I am speaking from experience. When they are cranked, you are expanding the shock and the piston is no longer in the center position. When you hit a dip the down stroke has more distance now but the return stroke is reduced and the piston hits the bottom of the cylinder and will, over time, break.

mine cranked 1 3/4" . the day i did it, i was driving home where my neighborhood has speed bumps, and definitly felt the front end got stiff and didnt handle bumps as well as before. so i ordered shocks from kennedy vendor, and it gave me a good ride back to my vehicle. so i definitly advise everybody........if ya crank the t-bars, get shocks!!!

I've never broken my shocks. I do have have Bilsteins on one truck, but imo they make the ride a bit rougher. It's more controlled over large bumps, but you'll feel every seem in the concrete on the highway.

Will cranking the t-bars for only 1" of lift require extenders too??

Thanks.

Probably not notice anything just driving around. But, as soon as you hit a good rut/pothole...your risking either a jarring effect or shock breakage. I'd do the extensions just to know I have full suspension travel not impaired by the shocks. Cognito and/or Norcal has nice ones for $30.

One side should be cranked more than the other. The driver's side carries the fuel tank as well as the transfer case. If you measure on a flat surface and the truck is level, the drivers side adjusters will have less threads showing. All trucks vary-ie: it's easier to get the front end of a single cab to go higher than a cc lb. It's all about weight transfer, whether the bars are stronger or not. Same goes for a gas vehicle-they are much lighter in the front end.

I just cranked mine 1 1/4''. Driver's side sat 1/4 lower with a full tank of fuel. Ride hasn't suffered too much--but sure does look better.

If you crank the bars 1" do you need to have an alignment??

Everyone I've talked to (dealer, mechanic's) say no.
