I saved a link to the 1st gen Hellwig sway bar offered by suspensionconnection.com for the time I had the $$$ to pick it up. They used to list it at $175. Now it is posted at $286.95!! Ouch...

"I finally found an honest mechanic. He honestly doesn't know how to fix anything."
If I have no plans to lift or lower my truck is there any advantage to the 7700 over the 7641?
Since I have no plans to lift or lower my truck would the 7641 be a better choice?
Also would a sway bar make a truck less likely to roll-over while on a hillside, kinda thinking out loud here?
The 7700 replaces the 7641 and is designed for stock vehicles as well. It is adjustable so that you can tune the sway bar to match your driving style. Roll over on a hillside depends on where the vehicle's center of gravity is located. Once the center of gravity is past the centerline of the wheel you are going to roll over whether you have a sway bar or not. The sway bar will make the vehicle more stable but will not prevent roll over if the angle of the hill places the vehicle's center of gravity outboard of the wheel.
Thanks Dave, I may have to get on this GB after reading the DIY thread, and thanks for the physics lesson.
Let me try to paint two different pictures
First, in your explanation we are on the side of a paved smooth hill that has a steadily increasing angle. At some point the center of gravity will be outboard of the wheels and roll-over occurs.
Second, we are on the side of a levee that has bumps. One of these bumps throws the center of gravity outboard of the wheels momentarily.
Does a sway bar lessen the chance of that happening.
This thinking out loud is coming as a result of reading Boosted27606's comment in the DIY thread.

That situation makes the rear suspension significantly softer yet more stable.
the HELLWIG REAR ANTI SWAY BAR.
although my truck say's it's a 05 toyota tundra double cab.
my truck feel's like a BMW or AUDI, now for almost a year now, since the install of the HELLWIG REAR ANTI SWAY BAR.
so far so good, all is tight, all bushing are mint, all hardware in place.
it's a dream come true! :-)
thankyou HELLWIG for the best product on the market!
you made my truck driving experience incrediable.
now,although i own a toyota it surely feel's like BMW or AUDI!
that's how awesome the truck handle's.

The sway bar will resist deflection from a bump on one side of the vehicle, however, there are a lot of variables - what side of the vehicle the bump is on, size of bump,speed, etc, etc. To generalize, a sway bar is great for street driving and moderate off-roading. But extreme off road (rock crawling) and off camber situations with bumps may not benefit from a sway bar.
Dave, the levee in question has been traversed previously during deer bow season and will be again this season. I was hoping to reduce my pucker factor this year.
It sounds like I would benefit from the sway bar, just not in the particular circumstance I was thinking about.
