This is a quote from an old thread; I did a search, but have a question?

The codes for Torsion bars are b-L is that correct ? L being the stiffest? How do I find out which ones I have?

Closest to "A" is stiffest, also I think with "1" and "2".

As far as I know, the two stiffest T-Bars out there are the "1" rated bars, which come from the Sport Trac, and the "B" rated bars, which where the heaviest available in the 4 Door Explorers. The "1" Bars are slightly stiffer than the "B" Bars.

Yea, is that stamp somewhere? Are they interchangeable so I could swap mine for the stiffest one availabele?
