1.08 torsion bars

72bluNblu, if your LCA is 14" Would that affect the bars rate? (keeping the same tire/rim between the 2 to reduce variables)

First, it's not changing the spring rate of the bar. It's changing the wheel rate.

And second, yes. Changing the length of the LCA, ie, the distance from the center of the torsion bar to the lower ball joint, does change the wheel rate.

Just look at the calculator. Torsion Bar Wheel Rate Calculator - Sway-A-Way | Racing Technology

For example, if you take a 1.08" bar, the same active length of 33.8, and use a 14" LCA instead of a 12.875" one, you get a wheel rate of 226.2 lb/in, instead of 267.4 lb/in like we calculated above with the stock length LCA.
