The traction bars made a big difference in several ways.
Firstly, they eliminate the axle wrap. Now, I'm not a dragracer, but when coming to a quick stop, like when a traffic light unexpectedly turns yellow, and you have to whoa it down pretty quick, it builds up some tension in the rear springs. Then when you take off once it turns green, it felt like the rearend had slid backward or something. That's the axle wrap. Well, it's GONE! The traction bars take any stress and deliver it right into the frame instead of into the springs, which shouldn't really have to deal with it.
Secondly, it corners better. It almost feels like I've got a rear sway bar on it now. I noticed this right away, and oddly enough, so did my passenger. It's more "point and shoot" now. There's no wander or loping and the side-to-side motion is all but eliminated. I think the truck stays more level around corners and that's translating into what I feel.
Third, as I said the sidesway seems to have gone away. You know how you rock side to side when you come out of a parking lot and cross that little raised dropcurb at an angle? You and your passenger slap your shoulders off the windows? Well, that's GONE! All you feel is a little vertical drop when you go over it now. No more swaying and rocking.
All in all, I really like how the traction bars make the truck ride and drive. It's a lot more direct control now and I don't think I even need a rear sway bar now. It's allowing the springs to do their job and the new shocks to do theirs... without having to make them multitask.
Well worth it IMO.
