Bumpstops vs swaybar

[72k5mike]

Just thinking out loud here.

I have considerably soft front springs on the front of my '72, they are toyota lift springs with an advertised rate of 220 lb/in. They are great, but as you can guess they have some significant body roll. I have corrected that problem with a sway bar.

Just a thought, would I be able to replace my sway bar with a set of properly setup hydraulic bumpstops? I was thinking of getting a set of 4" hydraulic stops and setting them very close to the axle when the truck is at ride height. Would this control some of the body roll?

Again, just thinking out loud here, let me know what your thoughts are

It could reasonably be setup to kind of act like a swaybar but then they won't really be set like an airbump should be set.

2 different items with completely different jobs use either for a job it wasn't built for and performance will suffer

If the problem was corrected with a sway bar, what are you trying to accomplish now?

What is your complaint with the current setup?

I don't think it would be very effective, since they wouldn't affect droop at all.
And that's half of a swaybars job.
Get a swaybar disconnect instead is my advice.

not trying to accomplish anything in particular here, just a thought. I probably cannot afford bumpstops right now anyway.

Is body sway more of compression of the suspension, more of droop of the opposite side, or both?

Also, anyone care how to share how to postion bumpstops properly?

Body sway is when the chassis rolls to one side. This compresses one spring and lifts weight off of or sags the other springs.
An anti-sway bar keep both halves of the truck connected to both halves of the axles. In theory keeping the axle/body parallel and the weight of the axle keeps the truck upright. Sway bars are designed to twist/bend giving give.
Bump stops are there to prevent the axle and other components from slamming into hard object such as the frame and getting damaged.
Your idea of using the bump stop would basically to slow down the travel of the body till the bump stop bottoms out on one side. That could be rigged up with a short shock absorber. The downside I see is that you're only controlling one side at a time and it'll be an abrupt stop causing more harm than good.
As I've made a short story long. It seems as though it'd be much cheaper and effective to use disconnects.

I actually have an air locking and unlocking sway bar that I designed and have been testing for the past year, works very well. I was just wondering about the bumpstops, I just didnt know how my theory would work
