Rockcrawler Torsion Bars

Be sure to drop it the rest of the way out.

Along with the A-Arms, etc etc etc.

You should be good to go.

Kidding...right. Ya wouldn't want to trash a 100 and make a POC buggy out of it. ;p

What am I missing?

 

[SINCITY100]

My suspension, up 2.75-inches works well though it takes a lot to stuff the wheel all the way which results in the rear-end picking up some slack or a quicker front wheel lift than normal.

I have to ask Shottz....How much down travel DO you have left with your t-bars cranked so high?...I cranked mine just under 3" during the installation of my OME kit, and I had close to ZERO droop..I could sqeel (spin) one the front tires by merely shifting the weight of the vehicle side to side under acceleration or on a slight bump....

And yes...that was the ONLY time I could get a front tire to break traction on dry pavement..(at least now I know what it sounds like on a 100 !!)

Just curious...Obviously larger tires will not affect droop or articulation, but are you (overall) pleased with the higher lift + big tires, or do you think its a trade off of sorts..? (I.E. more ground clearance is nice for some situations, but less lift/more articulation MAY help traction under extreme conditions ? )

I just want what is BEST for my baby !!

You have to have, have to have, have to have at least 2.5 inches of droop after a T bar adjustment or you are asking for a VERY unsafe vehicle on the road. Sin: I hope that you readjusted to get back to more of a 2 inch lift. I would hate to see you get into an emergency maneuver and flip your vehicle due to the lack of foot print.

I've never measured my droop, however the only time I can lift a front tire is under EXTREME high accelerated cornering and if there's an uneven surface.

At my setting I cannot agree to it being unsafe. Had I, I'd of changed it. I drive VERY aggressively and this thing is stable as can be. The stiffer spring rates help I'm sure. Even at 75MPH I can make quick lane changes andit tracks solid.

As far as off road, I need the neight I have if I want to take all the very aggressive lines. I won't give that capability up. IF ON THE OTHER HAND I wanted to run moderate trails I'd a kept to 33's, 2-inches lift and had been more than happy. I did run some quite difficult stuff that way before upsizing.

Why would these guys offer the T-bar in different lengths ? How would that effect the suspension ?

If you put a longer one in there, then you wouldn't have to crank them out so much to get the lift you wanted. I guess it makes sense, kind of like if OME would make one with the same spring rate they currently use but two inches longer. Then you would be able to use them without cranking them to their limit.

Oh..HECK YES ! I dropped the front end down to 2-1/4 in over stock because of the lack of droop AND the uneasy handling that (the overcranking) caused...(plus we couldnt even get the alignment in spec)....It was quite scary driving it even under "normal " conditions...I dont know how Shotts has a "safe" driving level when my experience was so different...unless the tire size his 35`s vs my stock 18`s make that much of a difference...

Hasn't been the case unfortunately.

There's only one length. One bat is for the V8 and the other is for the TD.

After reading this thread all I can think of is why the hell would you pay shipping from AU to US when you can choose from Sway-a-way and OME T-bars right here in the US?

Those big fat shocks may be worth shipping though Although, they are mfg. in Canada so you may find them in North America.

And the T-bars are offered in different lengths due to the Turbo Diesel IFS requiring a different length.

I am pretty sure those OME bars were shipped here at some point.

I tried a little googling but could not locate those shocks anywhere but AU.

Thanks for the answer on length.

Still, couldn't a longer T-bar be used to gain lift instead of cranking out a shorter one? When a shorter one is cranked out to give more lift, aren't you making it longer?

NO...The t-bars length has nothing to do with lift..its the twisting of the bar that
dictates height and spring rate..T-bars are consistant in length at all times...

Obviously, I don't have a good enough understanding of the T-bar and how it works. I'll have to go home and get under the 100 and check it out.

So, to get this straight, when the T-bar cycles, it doesn't change length externally, just internally? I definitely don't understand this concept yet. Sorry for my ingorance, all of my previous vehicles had SFA's. I'm new to the IFS scene.

Sin:

Just so he understands, Length (of the straight section in the T bar) has a lot to do with spring rate in a T bar. Actually, it one of the main variables in the spring rate formula-that and distance from anchor arm to center of wheel and the diameter of the bar.

Although the bars do not stretch, a longer or shorter bar will effect spring rate, which in the same index position as another bar, should affect lift.

 

[SINCITY100]

Sorry..correct..I was to referring to an individual model ( 100 ) or vehicle (only one length available for a particular L/C due to control arm/bracket limitations...) Thats why I said "length has nothing to do with "height" "... Is this right ?... I do realize that length would change rate, but only if you could actually install them on the same rig...

That's right, I'm a NOOB. But Schotts, you are the UBBER NOOB

And yes, the OME bars were shipped here in a big crate. Much cheaper than a little box And OME springs are fine, I just s*** talk their shocks!

Greg:

All a T bar does is provide countering force, in a simple (versus progressive) spring rate fashion to the A arm so that the weight of the vehicle is counteracted and the ride height is set to X. When you adjust the T bar it means to rotate the bar in a way-counter clock for DS and clock for PS so that when the vehicle weight (preload) is placed on the bars, the A arm goes to X position which is a lifted position in comparison from where you started. This does not give you more travel-only more ground clearance and tire clearance.

That's what I thought it did. OK, so then instead of rotating the bar to put more preload on it, can't you simply put in a longer one and not rotate it? This too, would give you lift because the longer t-bar would push down the A-arm causing a higher stance (also would reduce down travel). I'll look at it tonight, so that hopefully I don't sound like such a dumbass on later posts.
