One thins to remember, if you have 20 years on a spring and it snaps, you don't necessarily need a larger one. You just need a new one.

Our t-bars are holding up much better than most leaf and coil springs in the very same trucks are. Don't worry if one gives, just get another and enjoy an other 20 years.

As Abecedarian stated, and I'll paraphrase, you only need a stiffer t-bar if you need less flex. That is the only reason. In fact, when flexed to the bumpstops, the stiffer bar is under more stress, (equal strain) than the stock.

True, you don't necessarily need a larger one, but you might. If your bar broke because it repeatedly was stressed passed its yield strength then the bigger bar would help. If it broke because of 20 years worth of corrosion or fatigue then you just need a new one, springs do wear out. Would you agree with that Frank?

Oh certainly. The spring will strain harden over time which will make it more brittle. That will lead to failure. It's not really that big of a deal, it just what happens to metal that is flexed even within its elastic limits.

Since many of our trucks are approaching the 2 decade mark it is not suprising some springs are starting to fail. In almost all cases, the rears have been swapped out long ago. Just get new ones if you were happy with the old one before they failed.

I concur

mine broke from a big ass pothole and 14 years of rust. i put my new ones in 26mm and its def a stiffer ride but nothing to bad although offroad it would be pretty rough
