Pardon my ignorance. Can someone identify the parts in these photos? Thanks

I know one is a anti roll bar and one is an anti sway bar, but which is which.

Photo 1


Photo 2



Photo 3
I know this is a shock, but any idea what type or who makes it, its obvious its not factory.

 

1st photo is a sway bar.
2nd photo is just a crossmember.. its there to protect the transmissions... i threw mine away cause it would be dragging the ground now..
3rd photo looks to be a generic shock you can buy at Napa, Autozone, pep boys, Kragen... pick your flavor...

 

Thanks Domer! Photo 2, looks kinda like a anti-roll bar. Thats what threw me off. Is the Sway Bar stock on our trucks? Did they come like this from the factory, or is that something someone had to add on to it?

 

First a sway bar & anti roll bar are one in the same.
In the first photo the upper bar is a factory sway bar, & I think it was a option.
The lower bar in the first photo is a torsion bar. & the other a cross member,& almost everyone with a dropped truck ditches it!

 

how would it ride w/o the crossmember bar...

 

IV flattened. Two of those cross bars I never noticed a difference after i took it off these frames are pretty stiff. I did notice speedbumps are little easier

 

do these trucks come with factory anti-roll bars?
