Calling all shackle flippers

I have always liked the idea of flipping the shackles as a easy, cheap to gain a few inches of lift. I have never done it, but considered it many times.

BUT, after doing a lot of research about linking the rear axle for my "Molasses Project", I'm not so sure. I always wondered why the leafs are angled up at the back on the stock setup. It would appear that they did it for "roll steer" (or lack of it)

So what I'm asking is anyone who did the flip, did you notice oversteer on the highway after the flip? This would be like turning a little and having a little body roll and then feeling more turn. The actual numbers of the "roll axis" I have not figured out yet. But they must change a little. Maybe not enough to notice.

Curious to hear first hand.

I didn't notice anymore then I already had with the lift.

I did notice that the whole suspension seemed to get stiffer.

I ran the jbg shackle flip on the stock springs and gained about 5in in the rear. Ride was soft and flex was excellent. Lifted broncos handle like shite anyway but i noticed nothing out of the ordinary. I have since added to my spring pack and am now at nine inches of lift. Still no real problems to speak of. I say go for it. Only real issue ive found is the front hanger could stand to be moved about 1.5 inches to the rear. As far as oversteer or rearsteer issues who knows. 9in of lift and swampers makes for a new adventure everytime i hit the highway.

I didn't notice any handling diffrence on my f250 but it handles a lot better than my Bronco anyway. I do agree with japhethwar about it shifted the axle a bit forward. It looks funny once you notice it.
