Porche - there's a difference between lean, and rollover..and I understand what you're saying, but I've seen analogous situations where the amount of flex can let you whack a tree, etc...

I had a buddy in his TJ whack a tree I cleared on an offcamber section...he had 6" of lift and two live axles, and a shit load more wheel travel than I had....same line (Had to be the same line, it was a tight squeeze...)

I guess the best way to summarize it, as I took ALOT of measurements, etc...before running these on trails....is its about as flexy as a 4.5" SL.

My X, loaded for work, etc...is about 5,800 lb...and it would lean more than a lighter one for sure.

So, if the 4.5" Sl'd X leans into the tree, so might the Revolver shackled X, etc...and your buddy who had that accident perhaps fell victim to that principle.

Meaning, it has nothing to do with the Revolvers per se, just that a more flexy rig leans more...like the Jeep, it was a lot more flexy, had a lot more clearance, and leaned over into the tree, bashing its window/door frame (Didn't break though, very slow approach...)

People with a SAS for example have maybe 5" - 6" of SL, and I expect more total wheel travel than I have (Especially up front of course, but I'm talking about the butt end right now...)

So - if you get off camber with the SAS...you can lean more than I could with the Revolvers.

Maybe that will put it into perspective.

As for the leaf flex, I checked it, and as the axle twists the leaf...no other force is twisting the leaf but the axle...the two end points are anchoring it, but the leaf's twist is definetely coming from the middle.

When the axle drops and twists the leaf, if the hanger is fixed, like the front, a torsional force is applied to it.

If the rear hanger essentially CAN swivel, it can MOVE when the torsional force is applied, and rotate with the direction of force, relieving the tension.

Now, if you are talking about that with the Revolver, the FRONT hanger gets twisted harder, because the axle is drooping further...due to the Revolver, yes, but the amount is roughly equivalent to having another 1.5" of SL...a few degrees more is all that happens...the axle is a long lever, with the dropped tire's end pretty far from the leaf being twisted...

(Like the amount of twist with a 4' long lever moving 2 more inches down...the amount of additional twist is minimal.)

A front Orbit Eye would address that if you were going for more massive flex. I simply set up my travel to stay within the driveshaft travel and leaf flex limits...so I didn't need to make other arrangements for hangers....I did add longer shocks with 29" extended length....that's all I needed.

I've seen PLENTY of X's with broken leaf springs...None had revolver shackles. Is it POSSIBLE to break a spring ...sure, if you could do it w/o longer shackles, you could also do it with longer shackles.

I HAVE seen (Jeeps mostly..) not sweat the details, and install revolvers, and drop drive shafts, etc...because they did not compensate for the extra travel....and a jeep's rear shaft is like a foot long...not much to play with there.

This is just like the one's who mounted tires that were too large, and blew their drive trains.

Is there a flaw in large tires, or is that some people don't set up their rigs intelligently to handle it?

So - to clarify - Revolvers work great, and sure, just like doing an SL, or adding larger tires, or a locker, etc...it can open new issues..., like a locked diff can blow more easily, etc...but, the design itself works.

If you think the wheel travel of a 4.5" SL with the ground clearance f a 3" SL is nutz/too dangerous, get a 3" SL, and don't get revolvers.

If you want a bit more wheel travel w/o raising the COG as much/being able to still fit into some garages, the Revolvers are a practical option.



Some people are reacting to these things like your tires fall off... its only a few inches more of droop, there's people w/o the revolvers with new flexy leaf packs with just as much travel.

Your tires stay on the ground longer...that's about it.
