Thumbs up Boomerang Shackles...


Anyone else running these..?

Ok - So these came from Virginia 4X4 and are made from Waterjet cut A36 Structural Steel and they are 1" lift for YJ Jeeps! Uhhhhhhhh! Jeep parts on a Chevy Blazer, Say it ain't so!

So the Boomerang shape helps to kick the spring back quicker(flattening) at the end of the compression and helps to let it dangle a little more at full extension. Along with providing an inch of lift.

You can see in the pick that the straight shackle does have the chance to contact the structure underneath.

I did a lot of homework before buying such a thing and I hunted long and hard and the result paid off.

Just thought I would share!

Also, I've updated a few pics and built a Garrage Profile here as well - Check it out! I don't think my rig looks too bad for 205,500 miles!

Do they make the boomerangs bigger than 1 in? I was looking for a 2-3in shackle

Stock Shackle is 4"... These are 6" eye to eye. To get 2" lift they would have to be 8" long... Too Long in my opinion.

You really shouldn't go any higher than 1" lift/2" longer - You then have to adjust the pinion angle and the thrust angle on the front wheels too if you do...

If you don't know what any of that is, just get a 2" Body Lift - It's A LOT easier!

If they cost the same as a regular shackle, go for it, but a properly designed shackle will do the same thing as that. It doesn't cause the spring to lay any flatter. It doesn't move things any differently than a regular shackle would. It just is bent. In the end, it swings in the same arc as a straight shackle.

The only benefit I can see is that with the bend in it, the support point tying the two side plates together has more room between it and the frame. If it were welded together, I would like it more.

But again, a properly designed straight shackle can do the same thing. Just move the support to the front edge of the shackle

Want some flex? Try these. Pricey, but nice. They do require regular maintenance due to the moving parts.





Z-Box style...

Yeah - those are for the serious off-road looking to get every bit out of their rig. I was more worried about driveability to be honest, so things are kind of mild on my end!

And I was worried about contact between the frame and shackle as well.

Swartlkk - I was told it had a lot to do with the angle out of the shackle of the leaf spring as well. The spring moves up into the two elbows and is supported by the shackle. That's why they are 3/8" thick. Supposed to be less bucking around and for the jeeps they are made for, nearly impossible to force the shackle over center offroading.
