T-bar crank

I read somewhere that on a T-bar crank the most lift you can get after it settles is 1.75". And that with the 33" tires i have I would have to have the allinement checked and put cambers on to set the tires right...is this true? How high can I get on a t-bar crank

sounds about right, every truck is different. depends on alot of variables. you could get an alignement but dont have too.

Get it aligned...when cranking the t-bars your creating an off camber situation. It may not look like its that extreme, but it doesnt take much to crap out a set of tires.... your camber when aligned should look like this: |_|----------|_| <----That being your tires from a head on view..... When you crank your t-bars you cause a slight camber problem in which it will make your tires look like this (now rememeber this can be as little as .025" 's of a difference, it will ruin your tires over time.) /_/-----------\_\ or it may look like this \_\------------/_/ either way your gonna regret it if you dont get an alignment. Plus IIRC you were talking about installing a lift here shorty, I would wait on crankin your t-bars until you install the lift because after lifting your going to need to get an alignment any ways....so I say kill two birds with one stone!

Im guessing it's the same if you wanted to lower it, anybody know how much of a drop you can get from cranking on your torsions?

Actually it's the opposite THREE, if you lower it it would be likt this /_ /_____\ _\ and if you lift it, like this \ _\ _____ /_ /. Reason being: when you tighten the bolt to lift it, it puts more pressure on the torsion bars which in turn puts more pressure downward on the front suspension/control arms. When you do that it pushes them not only down but in as well, because the controls the same length would end up being shorter (not as wide from the front view) if pushed downward. Either way, get the alignment checked!

This is true for Twin I-Beam or Twin Traction Beam suspensions used on Rangers through 1997, not for 98+.

For 98+ Rangers with either of the SLA front suspensions, it doesn't matter whether you raise it or lower it. Either would push the wheels to negative camber (tires tilted inward at the top).

i jus cranked em on my 02 XLT, and the alignment shop said the alignment was perfect....your mileage may vary.....i got the print out so if/when it eats my tires i can go back and complain.
definatley at least get it checked after crankin either way.
if you loosen them to lower a truck, buy some wicking lock-tite. loosenin the bolts puts you in a treaded range that has no lock-tite from the factory.

ehh whatver...all that matters is you'll need an alignment no matter what if you lower it.

Probably not that much before you would run out of adjustment. Here is a How-to for a torsion bar drop but it requires reindexed torsion bar keys:

I've cranked my bars over a year ago, and went to get it aligned soon after, the shop said the alignment was perfect.
Because of the crank, at least I believe, my ball joints got worn out; I had to get all 4 replaced ( I only have 45k miles ). I wheel it hard though (prerunner stuff and jumping it) when I do wheel, which isn't much at all.
