I have a 95 wrangler with a 4" lift and straight shackles, I noticed this weekend there is not much downward travel, almost like the sway bars were still connected. Do you think the "Boomerang shackles " will help and are worth it?? ...pros??.....cons??...

I have homemade boomerang shackles on the front of my Samurai. It works great for giving lots of droop.
 
maybe someone can explain my flawed thinking, but with boomerang shackles the effective connection is still a strait line, so not sure how they can give more droop? I can see them allowing more uptravel in a situation where the shackle is limited by frame/body components.

Are you still running a panhard bar? Any pics of the suspension might help diagnose.
 
I had Teraflex Revolver shackles on the 95 YJ I had. Those allowed more downward travel. I won them in a raffle, I can't say that I would spend money on them if I had another YJ.

Your thinking is completely accurate. Shape doesn't matter except for extra clearance.
 
I read boomerang but was thinking revolver for some reason, LOL. I don't have boomerang shackles on the front of my Samurai. I have home made revolver or hinged shackles.

Revolvers I get completely. Toyota guys use boomerangs to clear the body mounts when doing RUF. If your shackles were contacting the front bumper on your yj, they might help get a few more inches of uptravel, but not down.

I bet it's a panhard, shock, or stiff spring issue that's limiting travel.
 
Will try to upload pics in a min. To me it seems like the front shackles are only swung forward a little bit and they more or less go straight on a down travel and then that is it. I an going to see if I can attach a video link, it is the first jeep an you can see where the tire comes off the ground.....

If the "Panhard bar" is the one that goes from the frame to the passenger side axle, then yes it is on there. I am new to jeep always had toyota. I daily drive the jeep quite a bit, would taking off this "Panhard bar" drastically decrease it's drivability?
 
Totally off subject , but PLEASE buckle your kids up
 
Removing panhard can have some side effects but many ppl run them on the street without the panhard.

I would check to make sure the shackle bolts aren't super tight.

Do you have a hoist or something to cycle the suspension ?
 
I'd try loosening the spring clamps up front some. Not remove them, but let them flex a little more freely. Other than that, checking shock lengths and spring eye tension.

They are, I run a set of lap belts for them. Thanks for looking out...


Ok thanks for all the input, I have some new bushings for the springs so I will install and check all the above.
 
Post a picture of the rig front the side.
 
Are you running a front sway bar and if so is it still connected.
Im looking at it on a 4" phone screen but when it carries the R front it looks like I see a sway bar end link screaming as it does its job. I cant zoom in enough and maintain image integrity to be sure.
 
Lap belts aren't worth shit. There's no good reason that your kid should be able to put his head out of the door opening while the vehicle is in motion.

It articulates more when both tires are on the ground than in the brief moment when it lifts the RF. Hard to tell from the video, but I'm betting there isn't much weight on the front end at that moment. At least there isn't enough weight to compress the left front and force the right side down to the ground.

How much droop is there under normal circumstances? If you support the vehicle by the frame, how far do the front tires fall away? How far is there between the axle and the bump stop at ride height?
 
Pics that were asked for...

That Panhard end in single shear with a fender washer on it is very... ...interesting. That's a double shear bushing and should be used in that manner. You could turn that heavy plate into a lighter duty double shear bracket and fix that though...

So again I have always been a toyota guy, this is my first jeep. Can you explain it a little more? How "should" it be mounted? What exactly is "double shear"??....thanks..
