Bump stops and T bars

[Jukelemon]

I must be having a brain melt down becasue I cannot understand how a new set of T bars allows for a lift without doing the exact same thing as cranking up your OE's. In other words, your A arm in the 100 does not change in terms of location so all that can occur is a lowering of the A arm which results in 1- lift and 2- Cv angle. The diff drop kit will take care of two but nothing will take care of 1's consequence on travel or droop.

Am I right on in this? Has any of you with the new t bars adjusted your stops or are you just trying to solve the issue of stuffing the tire versus rubbing?

Thanks.

To further complicate the issue (my issue), I have read several articles where they are referencing cranking the T bars as a normal response to 1- sagging old suspension and 2- addition of a winch or plow.

WTF????

The torsion bar is a spring. If you put one in that is a stiffer spring, then when you lower the truck, it just won't lower as much, ie, won't twist the bar as much.

By cranking torsion bars you are pre-loading them and achieve lift that way. However you are putting yourself closer to overstressing the torsion bar.

So it is merely (not minimalizing the purchase) a matter of stress or rigidity inthe t bars. Lower arm is going to set in the same position either way.

Got you.

Thanks.

Slee:

Have you seen a stock T bar fail? I am just curious. I mentioned some time back that my 100 series t bars were significantly larger than my 2004 Dodge 1500 Quad 4x4 T bars.

Have not seen a factory set fail, but do know that trying to crank them up to compensate for extra weight makes it drive like crap. To soft of a rate.

 

[Jukelemon]

Yeah, I can see that.

Many factory T-bars have failed out there (again, mainly Aussies) when cranked and supporting ARB bumpers/winches.

 

[Jukelemon]

right, I can see that. But I would be curious to know about non winched/bumpered 100's. Hell with it, I am going to do it myself and test the waters by buying the lift (total) but go one piece at a time. I'll report back on it.

The reason why I am thinking the preload issue is OK is becasue the stock t bars are so soft anyway. I do not know the tinsil (sp?) strength of the bars so it is hard to say at what point they would be in danger of failure. Anyone on that one?

Its not so much overstrssing the T bar, ut creating an unbalanced vehcile with different spring rates that is the bigger issue.

When we had 80's everyone just got new front springs for a lift, which were matced to the rear to a degree, and a T bar is just a coil spring which isnt round [works same way] but because T bars have an adjustment to level the car, people thing overloading them, and keep winding is the answer, when it isnt.
