Rear Sway Bar Question

[dagnabbitt]

I've read numerous threads on the efficacy of rear sway bars in our trucks... and as usual when I do that, I am not sure what to believe. The most informative threads are 10+ years old and are authored by former members, and I see no point in resurrecting them, so bear with me please.

I have two questions:

1. Is there any particular reason to NOT put a rear swaybar on a truck. Never mind a person's budget - lets say it is unlimited - or if it does little to improve handling vs the time and effort. Is installing a rear swaybar on a 2dw - stock or lowered, 1/2 or 3/4 - generally a good idea... or a bad idea.

2. There seems to be some disagreement over the efficacy of a rear swaybar in a coil spring truck vs a leaf spring truck. Is this a consideration, or a red herring. Is it a handling upgrade, regardless of the type of rear suspension?

I'd love to hear from you, thanks.
