Does the work "gimmick" mean anything to anyone [img]/wwwthreads_images/icons/wink.gif[/img]
Seriously, I have to laugh at their claims of like 10" of added droop - hooey!
Just like with a lift shackle, the actual lift is only half of the total extended length. This means that if the shackle opens up 10" over stock, then you are only getting about 5" more droop at the axle.
I personally don't like either Revolvers or Hypershackles because they incorrectly use the folding shackle design. Sure, they can be bolted on stock - which is their main advantage, but a folding shackle if done right works like the "Missing Link" design on samurai's... The upper part shoudl rest on the frame, letting the lower link work like a normal shackle and the upper link only comes into play when the droop is really needed.
And contrary to some people's claims, Hypershackles and Revolvers DO open up when they are not supposed to, and DO NOT always open up when you want them to. Since the Hypershackles are made here local to me, I have seen about a million sets on vehicles. I had a friend come over and I stood around while I made hin drive his rear Hypershackle equipped 4Runner on several obstackle behind the house. For 15 minutes I watched them do things I just would not be comfortable having happen on my vehicle. Most of the people I know who had Hypershackles on have now taken them off (including the 4Runner mentioned above).
The reason so many people like them is they are a modification that looks "cool" and require no permanent modifications so anybody can bolt a set on in the driveway and be done in no time. Sure, they offer some additional suspension droop, but there are better ways to get the flex that are a heck of a lot cheaper and work better overall.
If you have 'em - run 'em [img]/wwwthreads_images/icons/smile.gif[/img] I am just offering up my opinion
on why I don't like them...
