I prefer them. Simply put, they'll allow your rear suspension to flex (read "ride better") when your Bump is unloaded. When your Bump IS loaded, they'll increase it's load carrying capacity.

Thanks. That is the answer I was looking for. I found a parts truck without it and was wondering if getting rid of it was a wise move. Looks like I'll rebuild whats there.

the only upside i see to the non flexo is that you can lower with shackles, but i even found a way around that so i say fom is good all around.

This along with the extra PITA bushings to change for a flexo! :lol: Seriously though...I'd stick with it for reasons mentioned above but I'm not looking forward to changing 2 trucks worth of bushings for just one truck! Going with some polys though and I can't wait to feel it when I'm done.
