With all things being equal (same bushings, end links and solid construction) would a 1.25" factory F41 front sway bar have any disadvantage compared to an equal size aftermarket front sway bar?

Weight may be the only factor. Depends if the aftermarket bar is hollow or solid like the factory bar. Hollow bars are more susceptible to break, but if it's a well made bar, you probably won't.

USUALLY hollow bars are just slightly less stiff than the equivalent sized sold bar, but not by much. Not enough to notice on a G-body with a big block anyway.

I was comparing solid to solid.

OOps. My bad. I didn't read it well the first time...never mind. Depending on the steel, if it's about the same, diameter is the only real factor on stiffness. You probably won't notice any difference if the bars are solid and the same size.

If there was a significant difference, one would think the Aftermarket companies would advertise it... like: 15% Stiffer than the Factory 32mm Bar!!!

Because they don't seem to advertise the difference, the difference may not be very much.

This measurement would be super easy for MFG's to do with some weights and a caliper, so they probably have done it.

the chrome-moly ones are a stronger bar because of the heat treatments alone,compared to the standard oe bar of the same size that's merely annealed..they're bound to last longer than the 30+ year old ones most of us are currently running.
