yes, they keep the truck more planted through turns, im not going to get into physic specifics or anything but yes they are needed unless you are on a track that is real loose and no jumps.

Did you take them off ? Most truggies already have them installed on there. Quick way to see the difference is drive around a track with then take them off.

Yes, you want them. And learning how to adjust them (position of endlink, which thickness of bar) is a great chassis tuning tool.

but on a rough track whouldnt a swaybar, not work as good on a rough offroad track? because when you hit the ruts,you can see the wheels come off the ground, with a sway bar on.

If you move the endlinks in, effectively shortening the bar, it makes it "stiffer," by both reducing the leverage and reducing the length of the "spring." (A swaybar is just a funny-shaped spring connecting the 2 sides together.) Moving the endlinks nearer the end of the bar softens it by both increasing the length of the spring, and increasing the leverage applied. Simple, right?

This is good to know, it sounds liek it will kepp you from having to change the sway bar size, if you want it to be a little stiffer just move it in a tad....thanks Domit for the valuable info.....

Losi swaybars are shaped different... I'm not even sure they have much room for adjustment due to the extra bend at the end. Maybe if you reverse the ball link that goes on the bar.

Sway bars are a great tuning tool, and these days it seems rare for a truggy or buggy to come without sway bars. However, depending on the vehicle, your track, your driving style, and overall setup, should dictate whether or not you need sway bars. For instance, on my Mugen MBX5T, it was pushing horribly in the corners because the rear end had all of the traction and was pushing the front around. I removed the front sway bar and went to a lighter oil and softer spring up front to allow the front end to move around a bit more and get some more traction, and problem solved, it turned in much much better off and on power. For some trucks, you would need to do the opposite for the same effect. Just depends really. But, in most cases, a sway bar is a must.
